Additional Safety for Dust Collectors

1. MACHINE USE. Do not use this dust collec-

tor to pick up liquids and metal scraps, includ-

ing, but not limited to, nails and filings. Also,

do not pick up material which cannot safely

pass through the impeller such as solid wood

scraps.

6. AVOIDING FIRES. Do not allow steel to

strike against impeller—this may produce a

spark. Sparks can smolder in wood dust for

a long time before fire or flame is detected.

If metal contacts metal during operation,

immediately turn off the dust collector, flip

the disconnect switch and wait for all mov-

ing parts to stop. Remove collection bags

and empty the dust into an approved air tight

metal container in case of spark. Remedy

the metal to metal contact problem before

resuming operation.

2. KEEPING FINGERS SAFE. Do not place

your hands or tools near the open inlet during

operation. The moving impeller could cause

serious damage to body parts if touched

while spinning.

3. SAFE SERVICING. Disconnect power and

allow the impeller to come to a complete stop

before servicing or working on the dust col-

lector ducting system.

7. OPERATIONAL QUESTIONS. If at any time

you are experiencing difficulties perform-

ing the intended operation, stop using the

machine! Then contact our Tech Support

or ask a qualified expert how the operation

should be performed.

4. SUSPENDED DUST PARTICLES AND IGNI-

TION SOURCES. Do not operate the dust

collector in areas where explosion risks would

be high if dust were dispersed into the area.

Areas of high risk include, but are not lim-

ited to, areas near pilot lights and/or open

flames.

8. CLEANING AIR. Do not confuse this dust

collector with an air cleaner. This dust col-

lector is only designed to collect dust from

a machine, not clean dust suspended in the

air.

5. DUST HAZARD. Be aware that certain woods

may cause an allergic reaction in people and

animals, especially when exposed to fine

dust. Make sure you know what type of wood

dust you will be exposed to in case of an

allergic reaction. Always wear an approved

respirator during and for a short time after

machine operation!

9. EMPTYING DUST. When emptying dust

from the collection bags or drum, wear a

respirator and safety glasses. Empty dust

into an approved container and dispose of

properly.

No list of safety guidelines can be complete.

Every shop environment is different. Always

consider safety first, as it applies to your

individual working conditions. Use this and

other machinery with caution and respect.

Failure to do so could result in serious per-

sonal injury, damage to equipment, or poor

work results.

Like all machines there is danger associ-

ated with this dust collector. Accidents are

frequently caused by lack of familiarity or

failure to pay attention. Use this machine

with respect and caution to lessen the pos-

sibility of operator injury. If normal safety

precautions are overlooked or ignored, seri-

ous personal injury may occur.

Circuit Requirements

SECTION 2: CIRCUIT REQUIREMENTS

Serious personal injury could occur if you

connect the machine to the power source

before you have completed the set up pro-

cess. DO NOT connect the machine to the

power source until instructed to do so.

��

Circuit Requirements

Electrocution or fire could

result if this machine is

not grounded correctly

or if your electrical con-

figuration does not com-

ply with local and state

codes. Ensure compliance

by checking with a quali-

fied electrician!

We recommend connecting your machine to a

dedicated and grounded circuit that is rated for

the amperage given below. Never replace a circuit

breaker on an existing circuit with one of higher

amperage without consulting a qualiﬁed electri-

cian to ensure compliance with wiring codes. If

you are unsure about the wiring codes in your

area or you plan to connect your machine to a

shared circuit, consult a qualified electrician.

G0638 10 HP 220V 3-Phase...................40 Amp

G0638 10 HP 440V 3-Phase...................20 Amp

Phase Converter

When using a phase converter, the power from

the manufactured power leg (sometimes called

the wild wire) can fluctuate. Connect the manu-

factured power leg to the 3L/2 terminal to prevent

damage to the IC board or transformer. The wire

from this terminal can handle some fluctuation

because it goes directly to the motor. The power

going to the 1L/2 and 5L/3 terminals goes to the

IC board and transformer and must be consistent

to prevent damage.

Connection to Power

Have a qualified electrician hardwire this machine

to a dedicated locking shut-off switch (see Figure

2) that is connected to the main power source.

Site Considerations

Floor Load

Refer to the Machine Data Sheets starting on

Page 3 for the weight, footprint, and height speci-

fications of your machine. Some shop floors may

require additional reinforcement to support the

dust collection system.

Placement Location

Consider existing and anticipated needs, size of

material to be processed through each machine,

and space for auxiliary stands, work tables, other

machinery, and the operator when establishing a

location for your new machine. See Figure 9 for

the minimum clearance dimensions.

^��

��

^��

Figure 9. G0637/G0638 clearance dimensions.

Lighting

Lighting should be bright enough to eliminate

shadow in the working zones of the machine and

prevent eye strain. Follow local electrical codes

for proper installation of new lighting.

Children and visitors may be

seriously injured if unsuper-

vised. Lock all entrances to

the shop when you are away.

DO NOT allow unsupervised

children or visitors in your

shop at any time!

Figure 8. Model G0637/G0638 inventory Z-EE.

If any nonproprietary parts are missing (e.g. a

nut or a washer), we will gladly replace them; or

for the sake of expediency, replacements can be

obtained at your local hardware store.

Mounting to Shop Floor

Mounting to Shop

Floor

Clean Up

Some surfaces may be coated with a waxy oil to

prevent corrosion during shipment. Remove this

protective coating with a solvent cleaner or citrus-

based degreaser such as Grizzly’s G7895 Citrus

Degreaser. To clean thoroughly, some parts must

be removed. For optimum performance from

your machine, clean all moving parts or slid-

ing contact surfaces. Avoid chlorine-based sol-

vents, such as acetone or brake parts cleaner that

may damage painted surfaces. Always follow the

manufacturer’s instructions when using any type

of cleaning product.

We recommend that you mount your new dust

collection system to the floor. Because floor

materials may vary, floor mounting hardware is

not included.

Bolting to Concrete Floors

Lag shield anchors with lag bolts and anchor

studs (Figure 10) are two popular methods for

anchoring an object to a concrete floor. We sug-

gest you research the many options for mounting

your machine and choose the one that best fits

your specific application.

Gasoline and petroleum

products have low flash

points and can explode or

cause fire if used to clean

machinery. DO NOT use

these products to clean

the machinery.

NOTICE

Anchor studs are stronger and more per-

manent alternatives to lag shield anchors;

however, they will stick out of the floor,

presenting a tripping hazard if you decide

to move your machine.

Many cleaning solvents are

toxic if inhaled. Minimize

your risk by only using

these products in a well

ventilated area.

G7895—Grizzly Citrus Degreaser

This natural, citrus-based degreaser is a great

solution for removing export grease, and it’s much

safer to work around than nasty solvents.

Figure 10. Typical fasteners for mounting to

concrete floors.

NOTICE

Since your dust collection system will be

hardwired to the power source, we strongly

recommend securing your machine to the

floor. Consult with your electrician to ensure

compliance with applicable codes.

3. Use the (6) ⁵⁄16"-18 x ³⁄4" hex bolts and (6) ⁵⁄16"

flat washers to secure the intake cylinder to

the bottom of the blower housing (see Figure

16).

When using power lifting equipment dur-

ing the assembly, make sure the equipment

is safe, fully operational, and adequately

rated for the weight being lifted. The opera-

tor of the equipment must be experienced

and able to use safe methods during these

processes. Failure to heed these warnings

could result in serious personal injury or

death.

Note: Because the mounting bolts for the

intake cylinder are not accessible after

assembly is complete, consider using medium

strength (red) Loctite^©Threadlocker (Grizzly

Model H2509 or H2515) to ensure the fas-

teners will not come loose with operational

vibration.

Intake Cylinder and Blower Housing

1. Place the intake cylinder on the floor and

apply the 3 x 6 x 1800mm gasket to the

intake cylinder top rim, between the mounting

holes and the inside edge (see Figure 15).

NOTICE

Blower Housing and Intake Barrel

Assemblies

1. Apply the 3 x 6 x 2500mm gasket to the top

mating surface of the intake barrel assem-

bly.

When connecting parts that have a gasket

applied to the mounting surface, always

tighten the fasteners in a diagonal and rota-

tional manner to ensure the gasket does not

become crimped and compromise the seal.

2. Keeping the intake barrel assembly on the

floor, lower the blower housing assembly

over and approximately one inch away from

the intake barrel assembly.

designing the system

SECTION 4: DESIGNING THE

SYSTEM

Plastic duct is also a popular material for home

General

shops. However, be aware that there is a fire or

explosion hazard if plastic duct material is used

for dust collection without being grounded against

static electrical charge build-up. This topic will be

discussed later in this section. Another problem

with using plastic is that it is less efficient per foot

than metal.

The Model G0637/G0638 is designed to be a cen-

tral dust collector system. Locate the dust collec-

tor in an out of the way location such as a corner

or separate room. The large suction capacity of

the Model G0637/G0638 allows great flexibility

in planning and designing of your dust collection

duct layout. Grizzly offers a complete line of dust

collection accessories for setting up a stationary

system. Additionally, Grizzly offers a complete

guide book titled Dust Collection Basics.

Metal Duct

Advantages of metal duct is its conductivity and

that it does not contribute to static electrical

charge build-up. However, static charges are still

produced when dust particles strike other dust

particles as they move through the duct. Since

metal duct is a conductor, it can be grounded quite

easily to dissipate any static electrical charges.

Whatever system design you choose, always

make sure there are no open flames (including

pilot lights) in the same room as the dust col-

lector; otherwise you risk an explosion if dust is

dispersed into the air.

Duct Material

You have many choices regarding main line and

branch line duct material. For best results, use

metal duct for the main line and branch lines, then

use a short lengths of flexible hose to connect

each machine to the branch lines.

Figure 43. Examples of metal pipe and

components.

-28-

There are quite a number of options when it

comes to metal duct, but metal duct that is spe-

cially manufactured for dust collection is the best

choice. When selecting your metal duct, choose

high quality metal duct with smooth welded inter-

nal seams that will minimize airflow resistance.

This type of duct usually connects to other ducts

or elbows with a simple, self-sealing clamp, is

very quick and easy to assemble, and can be

readily dismantled and re-installed. This is espe-

cially important if you ever need to change things

around in your shop or add more tools. See the

Accessories section on Page 36 for examples.

There are also many kinds of pure plastic flexible

hose, such as non-perforated drainage type hose

and dryer vent hose. Drainage type hose, while

being economical, does not quite have the flex-

ibility required for dust collection. The inside of the

duct is also deeply corrugated and can increase

the static pressure loss by as much as 50% over

smooth wall duct. Dryer vent hose offers greater

flexibility, but is non-resistant to abrasion and

tends to collapse in a negative pressure system.

We DO NOT recommend using dryer vent hose in

your dust collection system.

If using flex-hose, choose one of the many types

designed specifically for the movement of solid

particles, i.e. dust, grains and plastics. However,

the cost of specifically designed flexible duct can

vary greatly. Grizzly offers polyethylene hose,

which is well suited for the removal of particulate

matter, especially sawdust, since it is durable and

completely flexible. Polyethylene is also very eco-

nomical and available in a wide variety of diam-

eters and lengths for most applications.

Avoid inferior metal duct that requires you to cut it

to length and snap it together. This type of duct is

time consuming to install because it requires you

to seal all the seams with silicone and screw the

components on the ends with sheet metal screws.

Another disadvantage is the rough internal seams

and crimped ends that unavoidably increase

static pressure loss.

Flexible Duct

Plastic Duct

Flexible hose is generally used for short runs,

small shops and at rigid duct-to-tool connections.

There are many different types of flex hose on

the market today. These are manufactured from

materials such as polyethylene, PVC, cloth hose

dipped in rubber and even metal, including steel

and aluminum.

The popularity of plastic duct is due to the fact

that it is economical and readily available. It is

also simple to assemble and easily sealed against

air loss. The primary disadvantage of plastic duct

for dust collection is the inherent danger of static

electrical build-up.

The superior choice for flexible ducting is metal

flex hose that is designed to be flexible and as

smooth as possible to reduce static pressure

loss.

components.

Step 3. Sketch a Basic Duct Layout

For the next step, sketch how your machines will

connect to the dust collector. Consider these gen-

eral guidelines for planning an efficient system:

System Design

Step 1. Decide Who Will Design

For most small-to-medium sized shops, you can

design and build the dust collection system your-

self without hiring engineers or consultants. We

have included some basic information here to get

you started on a dust collection system design.

1. Machines that produce the most sawdust

should be placed nearest to the dust collector

(i.e. planers and sanders).

2. An ideal design will feature the shortest pos-

sible main line and secondary branch ducts.

See Figures 47 & 48 for ideas of good duct

layouts vs bad duct layouts.

If you have a large shop or must design a com-

plicated system, then we recommend additional

research beyond this manual, or seek help from

an expert.

��

Step 2. Sketch Your Shop Layout

Planning is the most important step when design-

ing a successful dust collection system.

��

Before you begin to draw your necessary layout

sketch, we recommend that you visit our FREE

Workshop Planner available on our website at

www.grizzly.com.

��

Our Workshop Planner will allow you to quickly

and easily draw and print a basic shop layout.

Don't worry, non-Grizzly brand machines can be

substituted with Grizzly machines for layout pur-

poses. Note: After you're finished, make sure to

save your layout for later modification.

Figure 47. Good duct layout.

Your sketch only needs the basic details of the

shop layout, similar to Figure 46, including all

your current/planned machines and your planned

placement of the dust collector.

3. Directional changes should be kept to a mini-

mum. The more directional change fittings

you use directly increases the overall resis-

tance to airflow.

If your machine does not have a built in dust port,

use Figure 50 to determine the size of dust port

to install on your machine.

4. Gradual directional changes are more effi-

cient than sudden directional changes (i.e.

use the largest corner radius possible when

changing hose or pipe direction).

5. Each branch line should have a blast gate

immediately after the branch to control suc-

tion from one machine to another.

6. The simpler the system, the more efficient

and less costly it will be.

Step 4. Determine Required CFM of

Each Machine

Since each machine produces a different amount

of sawdust, the requirements for the minimum

amount of CFM needed to move that sawdust is

unique to the machine (for example, a planer pro-

duces more sawdust than a table saw). Knowing

this required CFM is important in gauging which

size of duct to use.

Figure 49 will give you a close estimation of the

airflow your machine requires. Machines that

generate the most sawdust should be placed near

the dust collector. If the machine has multiple

dust ports, the total CFM required is the sum of

all ports.

Figure 50. Dust port size and quantity per

average machine.

Write the required CFM for each machine on your

sketch, as shown in Figure 51.

Determining Main Line Duct Size

The general rule of thumb for a main line duct is

that the velocity of the airflow must not fall below

3500 FPM.

��

For small/medium sized shops, using the inlet

size of the dust collector as the main line duct size

will usually keep the air velocity above 3500 FPM

and, depending on your system, will allow you to

keep multiple branches open at one time.

��

For the Model G0637/G0638 this is 10". Mark your

drawing as in Figure 52.

Figure 53. Branch line sizes labeled on sketch.

��

A few frequently asked questions when deter-

mining branch line sizes:

What size of branch line do I use if the machine

has two dust ports?

Simply add the total CFM given for each size from

Figure 49 and refer to that CFM number in Figure

54. Then, split the branch line just before the dust

ports with matching duct sizes.

��

How do I manage two machines on the same

branch line?

You have two options:

Figure 52. Main line size labeled on sketch.

1. If both machines will be running at the same

time, add the total CFM given for each size

from Figure 49 and match the branch line

given in Figure 54.

Determining Branch Line Duct Size

The general rule of thumb for a branch line duct is

that the velocity of the airflow must not fall below

4000 FPM.

2. If both the machines will never be run at the

same time, reference the machine with big-

gest dust port in Figure 54 and add blast

gates after the Y-branch to open/close the

line to each machine.

For small/medium sized shops, using the dust

port size from the machine as the branch line duct

size will achieve the correct velocity in most appli-

cations. However, if the dust port on the machine

is smaller than 4", make the branch line 4" and

neck the line down right before the dust port.

Branch Line Size

Note: Systems with powerful dust collectors work

better if multiple blast gates are left open. This

also allows you to run two machines at once.

Experiment with different combinations of blast

gates open/closed to find the best results for your

system.

In most small/medium shops it is only necessary

to calculate FPM for the line with the longest duct

length or the most fittings (operating under the

assumption that if the line with the highest resis-

tance works, the others will be fine).

Calculating Duct Resistance

Adding duct work, elbows, branches and any

other components to a duct line increases airflow

resistance (static pressure loss). This resistance

can be minimized by using rigid (smooth) pipe

and gradual curves, as opposed to flexible pipe

and 90˚ elbows.

To calculate the static pressure loss of any

given line in the system, follow these steps:

To help you think about this resistance, imagine

riding a bicycle in a tunnel that is an exact replica

of your duct work. If the inside of the tunnel is very

bumpy (flexible pipe) and has many sharp turns

(90˚ elbows), it will take a lot more effort for you to

travel from one end to the other than if your path

had been smooth and straight.

1. Make a list of each size duct in the line,

including the length, and multiply those num-

bers by the static pressure loss value given in

Figure 55.

2. List each type of elbow or branch and multiply

the quantity (if more than one) by the static

pressure loss given in Figure 55.

The purpose of calculating this resistance is to

determine if it is low enough from the machine to

the dust collector to meet the given requirement

for the machine. Use the charts in Figure 55 to

calculate the resistance of duct work.

3. Add the additional factors from Figure 56 to

your list.

Note: When calculating static pressure loss to

determine if multiple lines can be left open at the

same time, only include the main line numbers

once.

System Grounding

Since plastic hose is abundant, relatively inex-

pensive, easily assembled and air tight, it is a

very popular material for conveying dust from

woodworking machines to the dust collector. We

recommend using flexible hose (flex-hose) to con-

nect the woodworking machine to the dust collec-

tion system. However, plastic flex-hose and plastic

duct are insulators, and dust particles moving

against the walls of the plastic duct create static

electrical build up. This charge will build until it

discharges to a ground. If a grounding medium

is not available to prevent static electrical build

up, the electrical charge will arc to the nearest

grounded source. This electrical discharge may

cause an explosion and subsequent fire inside

the system.

5. Compare the total static pressure loss for that

line to the maximum static pressure rating

of your dust collector (refer to the Machine

Data Sheets on Pages 3 & 5).

—If your static pressure loss is below the

static pressure rating of the dust col-

lector, then the line will most likely be

successful. Congratulations! You've just

designed your own dust system. Refer to

the Accessories section on Page 36 to

start buying the components necessary to

make your system a reality.

—If your static pressure loss is equal to or

above the static pressure rating of the dust

collector, then that line will not effectively

collect the dust. You must then modify

some of the factors in that line to reduce

the static pressure loss. Some of the ways

to do this include 1) installing larger duct,

2) reducing amount of flexible duct used,

3) increasing machine dust port size, 4)

moving machine closer to dust collector to

eliminate duct length, and 5) reducing 90˚

elbows or replacing them with 45˚ elbows.

To protect against static electrical build up inside

a non-conducting duct, a bare copper wire should

be placed inside the duct along its length and

grounded to the dust collector. You must also

confirm that the dust collector is continuously

grounded through the electrical circuit to the elec-

tric service panel.

If you connect the dust collector to more than one

machine by way of a non-conducting branching

duct system and blast gates, the system must still

be grounded as mentioned above. We recom-

mend inserting a continuous bare copper ground

wire inside the entire duct system and attaching

the wire to each grounded woodworking machine

and dust collector.

Be sure that you extend the bare copper wire

down all branches of the system. Do not forget

to connect the wires to each other with wire nuts

when two branches meet at a “Y” or “T” connec-

tion.

SECTION 6: OPERATIONS

Operation Safety

Do NOT put hands or

small objects near inlet

openings during opera-

tion. Objects sucked

into the inlet will meet

with the impeller blade.

Failure to heed this

warning could result in

property damage or per-

sonal injury.

Damage to your eyes, lungs, and ears could

result from using this machine without

proper protective gear. Always wear safety

glasses, a respirator, and hearing protection

when operating this machine.

General

Operating your Model G0637/G0638 is simple

and straightforward. Blast gates located at each

of the machines controls the air flow from the

woodworking machine to the dust collector. If a

machine is not being used, keep the blast gate

closed to maintain higher levels of efficiency

throughout the system.

DO NOT use the dust collector for any

other purpose besides collecting dust from

connected woodworking machines. A dust

collector should NEVER be used as a shop

vacuum and IS NOT a substitute for an air

filter system. For safest use, wear a respira-

tor and use an air cleaner in addition to the

dust collector.

Remote Control

The remote control for the Model G0637/G0638

is IR (infrared) rather than RF (radio frequency) to

prevent accidental startups by other common RF

items like garage door openers.

NOTICE

If you have never used this type of machine

or equipment before, WE STRONGLY REC-

OMMEND that you read books, trade maga-

zines, or get formal training before begin-

ning any projects. Regardless of the con-

tent in this section, Grizzly Industrial will

not be held liable for accidents caused by

lack of training.

Because this remote system is IR, the remote

control must be pointing directly at the control box

with an unobstructed line-of-sight view.

If you place your dust collector in a different room

or outside of your shop, you must mount the switch

in the shop and wire it through the wall to the dust

collector to make use of the remote control.

SECTION 7: MAINTENANCE

Cleaning Filters

Always disconnect power

to the machine before

performing maintenance.

Failure to do this may

result in serious person-

al injury.

The Model G0637/G0638 dust collector has a

gentle brush system inside the canisters for

removing any built-up dust from the filter pleats.

To avoid damage to your

eyes and lungs, always

wear safety glasses and

a respirator when working

with the dust collection

bags.

Schedule

For optimum performance from your machine,

follow this maintenance schedule and refer to any

specific instructions given in this section.

Daily Check:

•

Dust collector is completely powered down at

the end of use.

Dust collection drums and bags.

Loose mounting bolts.

Pressure leaks.

Worn or damaged wires.

Any other condition that would hamper the

safe and efficient operation of this machine.

filters.

To clean the filters, pull the red handles down all

the way, then pull the black handles down and

hook them in place.

How quickly the drum will fill up is based on the

type of work being done at the time:

Note: Always make sure to leave the red handles

in the up position to ensure that the brushes

return to their proper position and do not restrict

the filter.

•

Fine dust from a sander or table saw will

slowly fill the drums.

•

Curly shavings from a planer or jointer will

quickly fill the drums.

For a more thorough cleaning, remove the filters

from the dust collector and rinse them with clear

water. Allow the filters to air dry. Do not leave the

filters in the sun to dry or apply heat to speed the

process; heat exposure can damage your filters.

In the beginning, check your drums regularly to

get an idea of how often they need to be emp-

tied.
