Blade Designs  
L Propeller: Swept, steeply pitched blade design. These propellers typically run  
at lower RPMs and generate low sound levels making them the best selection for  
sound critical applications or applications that require the best combination of  
both air and sound performance. Typically used when the static pressure is 0.5 in.  
wg (13 mm) or less.  
H Propeller: Straight, moderately pitched blade. It is designed for applications  
where static pressures are above 0.5 in. wg (13 mm). These propellers typically run  
at higher RPMs and generate slightly higher sound levels than the “L” propellers.

Standard Wall Mounting  
Mounting Fan Directly to Wall  
The split drawing below illustrates the typical ways of mounting fans directly to the wall when a wall housing  
or collar is not used.  
For exhaust fans, there is a minimum dimension (M) which must be maintained between the propeller and  
damper or guard to achieve optimum performance (failure to meet this minimum dimension will result in loss  
of fan performance, increased noise and shortened fan and damper life). There is also a minimum required wall  
opening dimension (W.O.) to allow the venturi to fit into the wall opening.  
See the chart at right for the minimum “M” and wall opening dimensions.

Standard Horizontal Mounting Option  
Horizontally mounted fans are available for applications requiring vertical airflow. Typical applications  
include mounting fans in ductwork or plenums as transfer fans or suspending them from the ceiling in a  
wall housing for use as recirculation fans. Both belt and direct drive fans can be horizontally mounted.  
Motors can be mounted on top or on bottom with airflow up or down. Specify configuration best suited for  
access and service.  
Horizontally mounted fans are put under different stresses than fans mounted in a wall. Construction  
modifications are required depending on motor location (top or bottom) and whether the fan is belt or direct  
drive.  
These modifications may include the following:  
A - Grooved shaft with snap rings  
(belt drive fans)  
B - Motor pulley retaining hardware  
(belt drive fans with motor on bottom)  
C - Reinforcing angles on fan panel - not shown  
(all fans with motor on bottom)

Other Options and Accessories  
Electrical  
Disconnect Switches  
Toggle type and heavy duty disconnect switches are available for positive  
electrical shut-off and safety in servicing fans. The following switches are  
available to meet individual electrical requirements and can be factory  
mounted or shipped loose for field mounting. Wiring from the motor to the  
disconnect box is provided with factory mounted disconnect switches.  
• NEMA-1 - General purpose  
• NEMA-3R - Rainproof  
• NEMA 4 - Watertight  
• NEMA-3R & NEMA 4 - Heavy Duty  
• NEMA-7 & 9 - for Class 1 and Class 2 hazardous locations.  
NEMA-3R  
and NEMA-1  
1-Point Wiring  
Available when the following items are selected: common  
voltages on the motor and the actuator, disconnect mounted  
and wired and a wall housing. The wires are pulled from the  
motor and the actuator on the damper to the disconnect box.  
(Hard wiring of the components to the disconnect switch is by  
others.)  
1-Point wiring  
Junction Box  
or Disconnect  
Exception: When a specific voltage is not available on the  
actuator, Greenheck will provide a hard wired transformer  
to the actuator. Greenheck will then pull the wires from the  
transformer to the disconnect box.  
UL/cUL 705  
All belt and selected direct drive fans with TE standard efficiency, single speed motors are available with the  
UL705 listing for electrical.  
Extended Wiring Pigtail  
Available only in conjunction with factory mounted disconnect switches, liquid tight wiring pigtails allow direct  
hook-up to the power supply which eliminates field wiring at the fan. Internal or external power supply can be  
specified.  
End Switches  
Factory mounted end switches allow the damper to open completely before the fan is energized. This will reduce  
the back pressure and brake horsepower load on the fan motor at startup. (Field supplied motor starter with a  
relay is required to complete the wiring on a system using an end switch.)  
Options  
Coatings  
A variety of special coatings ranging from enamels to phenolics are available for decorative or protective  
purposes. When a special coating is selected for the fan, all accompanying accessory items are also coated  
unless so specified. Consult your local representative for more details.  
Welded and Painted Fan Construction  
For applications where extra heavy construction is required, welded steel construction is available. With this  
option, all stationary connections which are normally bolted are welded and coated with an industrial grade  
paint. This option applies to belt drive level 3 fans and direct drive level 2 and 3 fans only.  
Propeller Fan Rotation Guide

Download from Www.Somanuals.com. All Manuals Search And Download.  
Basics of Fan Selection  
The first consideration in any fan selection is the amount of air to be moved and the resistance to this air  
movement. With specific performance and application criteria in mind, propeller fan selections typically  
require decisions based on the following criteria.  
How Accessories Affect Static Pressure  
Belt Drive vs. Direct Drive  
All accessory losses must be accounted for when  
calculating a fan’s static pressure load. In most  
cases dampers, guards and weatherhoods actually  
add very little to the total system pressure. This  
means that propeller fans used in conjunction with  
common accessories can typically be specified  
with low pressure capabilities (below 3⁄8 in. wg).  
However, in cases where airflow velocities exceed  
1500 fpm through the damper or where filters are  
used, static pressure loss may be significant. For  
more specific information on pressure losses due  
to accessories, refer to pages 9 and 10.  
Belt drive fans offer the ability to adjust fan speed  
for system balancing if necessary. They also offer  
more flexibility in speeds and motor selections. In  
a cost comparison, belt drive fans are typically less  
costly than comparable size direct drive fans with  
low speed motors.  
Direct drive fans are often preferred for jobs where  
maintenance access is difficult. Maintenance costs  
are generally lower with direct drive fans, since  
there are no belts or bearings to replace and no  
pulleys to adjust.  
Larger Fans vs. Smaller Fans  
Motor Service Factor  
In most applications, several fans may meet the  
specified airflow and pressure requirements. Just  
as larger fans tend to turn slower and generate  
less sound, they also tend to have higher initial  
costs but lower operating costs. Smaller fans, with  
their higher speeds, have more stable performance  
curves, lower initial costs, higher sound levels, and  
higher operating costs.  
Motors for sidewall propeller fans are cooled  
by the airstream. With an uninterrupted flow  
of cooling air, motors may be operated in their  
service factor range (up to 20% above the motor’s  
nameplate horsepower) without damage due to  
overheating. Lesser overloads are recommended  
for applications using totally enclosed or explosion  
resistant motors.  
Low Sound vs. High Static Pressure  
Belt drive performance tables in this catalog show  
two speed selections for each propeller type (L or  
H) at a given motor hp. The first selection is a 1.0  
bhp service factor. The second speed selection is  
at 1.2 bhp service factor. Direct drive performance  
tables show BHP levels with service factors ranging  
up to 1.2 bhp. When a selection at 1.2 bhp service  
factor is not desirable for the application, specify  
the next higher motor horsepower.  
Fans selected for high static pressures run at  
higher speeds and produce higher tip speeds,  
resulting in higher sound levels. Conversely, in  
low pressure applications, fans generally run at  
lower speed producing lower sound levels and are  
recommended for sound sensitive applications.  
Direct Drive Model Number Code  
The model number system is designed to completely identify the fan. The correct code letters must be  
specified to designate direct drive with exhaust or supply air configuration. The remainder of the model  
number is determined by the size and performance selected from pages 15 through 21.

Performance certified is for Models SE1/SS1 for installation type A: free inlet, free outlet. Power rating (BHP) does not include transmission losses.  
Performance ratings do not include the effects of appurtenances (accessories). *Speed (RPM) shown is nominal. Performance is based on actual speed of test.  
The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301. Values are for installation  
type A: free inlet hemispherical sone levels.  
Numbers in blue have a larger BHP and require the next size larger motor.

Performance certified is for Models SE2/SS2 for installation type A: free inlet, free outlet. Power rating (BHP) does not include transmission losses.  
Performance ratings do not include the effects of appurtenances (accessories). *Speed (RPM) shown is nominal. Performance is based on actual speed of test.  
The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301. Values are for installation  
type A: free inlet hemispherical sone levels.  
Numbers in blue have a larger BHP and require the next size larger motor.

Performance certified is for Models SCE3/SCS3 for installation type A: free inlet, free outlet. Power rating (BHP) does not include transmission losses.  
Performance ratings do not include the effects of appurtenances (accessories). *Speed (RPM) shown is nominal. Performance is based on actual speed of test.  
The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301. Values are for installation  
type A: free inlet hemispherical sone levels.  
Numbers in blue have a larger BHP and require the next size larger motor.

Using The Performance Table  
Shown below is a portion of a typical performance table used in this catalog. Performance data shown  
offers the best selections for each propeller type (“L” or “H”) relative to sound, RPM and static pressure.  
Consider “L” type propellers first for most applications.  
Many sidewall applications can be met with the “L” type propeller. When using the performance tables, look  
first at the “L” selections, because they offer the lowest speed and sound levels.

Performance certified is for Models SBE/SBS for installation type A: free inlet, free outlet. Power rating (BHP) does not include transmission losses.  
Performance ratings do not include the effects of appurtenances (accessories). *Speed (RPM) shown is nominal. Performance is based on actual speed of test.  
The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301. Values are for installation  
type A: free inlet hemispherical sone levels.  
*Sones shown apply to the highest cataloged CFM in black type at each fan RPM. For selections at other CFM and static pressure points, refer to the CAPS  
computerized selection program.  
Numbers in blue have a larger BHP and require the next size larger motor.

Performance certified is for Models SBE/SBS for installation type A: free inlet, free outlet. Power rating (BHP) does not include transmission losses.  
Performance ratings do not include the effects of appurtenances (accessories). *Speed (RPM) shown is nominal. Performance is based on actual speed of test.  
The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301. Values are for installation  
type A: free inlet hemispherical sone levels.  
*Sones shown apply to the highest cataloged CFM in black type at each fan RPM. For selections at other CFM and static pressure points, refer to the CAPS  
computerized selection program.  
Numbers in blue have a larger BHP and require the next size larger motor.

Performance certified is for Models SBCE/SBCS for installation type A: free inlet, free outlet. Power rating (BHP) does not include transmission losses.  
Performance ratings do not include the effects of appurtenances (accessories). *Speed (RPM) shown is nominal. Performance is based on actual speed of test.  
The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301. Values are for installation  
type A: free inlet hemispherical sone levels.  
*Sones shown apply to the highest cataloged CFM in black type at each fan RPM. For selections at other CFM and static pressure points, refer to the CAPS  
computerized selection program.  
Numbers in blue have a larger BHP and require the next size larger motor.
