Powermatic PM1200 Air Filtration System
A large portion of the design and engineering effort behind the
Powermatic PM1200 Air Filtration System was devoted to striking
a good balance between airflow volume and efficient filtration.
Even the fins on the blower fan were subjected to considerable
research and development to be sure they made the most effective
fan for this application. The result is an air filtration system
specifically designed from the ground up to function effectively in
the woodshop environment.
The PM1200 Air Filtration System
is loaded with features that make it
versatile and a great value for the
workshop.
Legitimate Efficiency
It is important to understand the filtration numbers so
often used to describe the efficiency of an air filter.
Statements like “filters particles down to 5 microns”
actually tell you little about efficiency. It is crucial to
know the percentage of those particles actually captured
as no filter is 100% effective. Increasing the filtration
efficiency for a 1-micron particle for example becomes
exponentially difficult. Knowing the percentage of a
specific particle size an air filtration system removes is
the only true indicator of how it will perform in your
shop.
A considerable amount of engineering was
expended in the design of the PM1200 AFS
filtration elements to ensure maximum
efficiency.
We at POWERMATIC believe in providing the most
accurate and understandable efficiency numbers for all of our dust collection and air filtering
equipment. That gives you the best information possible on which to base your buying decisions.
The Powermatic PM1200 Air Filtration System uses two filter stages, the outer to capture large
particles and the inner smaller particles. The outer filter removes 99% of 5-micron particles. The
inner filter captures 85% of 1-micron particles.
Filters
To make it easier to maintain
the Powermatic PM1200 Air
Filtration System we use 12” X
24” X 1” filters on the intake
side. That size was picked
because they can be found at
virtually any local home center.
The diffusion filter on the exit
side does not require
replacement in most cases and
can be cleaned periodically
The inner and outer filter elements (left) can be removed or installed (right)
without tools.
We also added a programmable timer. This lets you set the Powermatic PM1200 Air Filtration
System to run for one to nine hours to thoroughly clean the air after work has stopped. When the
timer expires, the Powermatic PM1200 Air Filtration System shuts down automatically.
A re-settable, pop out fuse protects the Powermatic PM1200 Air Filtration System in the event of
an overload or power surge. After three to five minutes, push the fuse button and restart the
Powermatic PM1200 Air Filtration System.
We also added a “change filter” light that comes on after 200 hours of use. This indicator is
intended as a guide or reminder. The actual intervals between cleaning or replacing filter media
is determined by how much dust is being made in the shop. The change filter light has a reset
button (accessed with a paper clip or similar wire) on the control panel of the Powermatic
PM1200 Air Filtration System.
The remote control that comes with the Powermatic PM1200 Air Filtration System operates on a
radio frequency rather than an infrared beam. Using radio frequency eliminates the line-of-sight
limitation of the infrared types. The radio frequency remote supplied with the Powermatic
PM1200 Air Filtration System works from anywhere in the shop or even from other nearby
rooms.
Mounting and Locations
At 67 pounds the Powermatic PM1200 Air Filtration
System is relatively light but requires a safe, secure
mounting. High quality, appropriately sized fasteners that
are properly installed into joists or rafters is required. We
recommend avoiding the use of open hook-type
connections. Using self-closing clip or loop-style
connections will prevent one or more corners of the
Powermatic PM1200 Air Filtration System from detaching
Along with the remote we include a hardware
pack with threaded eyelets, nuts and washers
to make hanging the PM1200 AFS easy and
safe.
should it be struck accidentally by a project or piece of
wood.
The innumerable variations in the shape and configuration
of woodworking shops make recommending standardized mounting locations virtually
impossible. In many cases placing the Powermatic PM1200 Air Filtration System parallel to one
of the walls will help promote circulation of the air within the space for the most effective
cleaning of the air. In very large shops, two or more Powermatic PM1200 Air Filtration Systems
can be installed nose-to-tail to more effectively clean the large volume of air.
If there is a particularly dusty location such as a permanent sanding station, some find it helpful
to install the Powermatic PM1200 Air Filtration System so that the exit (filtered) airflow washes
over that area. That introduces a stream of “rinsed” air to the immediate area and promotes
circulating the contaminated air around the room to the inlet side of the Powermatic PM1200 Air
Filtration System.
