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.
Legitimate Efficiency
The PM1200 Air Filtration System
is loaded with features that make it
versatile and a great value for the
workshop.
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

efficiency.
specific particle size an air filtration system removes is
the only true indicator of how it will perform in your
shop.
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.

side does not require
replacement in most cases and

with a vacuum or compressed air. The outer filters could require more frequent cleaning or
replacement in exceptionally dusty environments to maintain maximum filtering efficiency.
POWERMATIC does offer replacement filter elements for the Powermatic PM1200 Air
Filtration System. We have specialized filter elements available including a washable (outer)
intake filter #1791085. We also have a charcoal diffusion filter element (#1791084) that aides in
removing non-flammable vapor contaminants and odors.
Filter Guards
Special attention was given to the inlet and outlet filter guards. The
Powermatic PM1200 Air Filtration System filter guards are not only
stylish but functional and do more than simply protect the filter
elements from damage.
Both the inlet and outlet filter guards are easily removed and
installed without tools. This eliminates trying to extract screws or
operate complicated latches while on a ladder. The Powermatic
PM1200 Air Filtration System grilles are secured with simple,

finger-operated catches so they come off easily but stay in place
during use.
The inlet filter guard is designed to help straighten the air as it
enters the filter elements behind it. The exit filter guard works with
the diffusion element to disperse the air as it leaves the Powermatic PM1200 Air Filtration
System to limit disturbing nearby standing dust that could be dislodged and added to the
suspended contamination.
Controls
Woodworking shops have changing levels of dust
contamination so we added a full set of controls to the
Powermatic PM1200 Air Filtration System. And, all of
those controls are available on the Powermatic PM1200
Air Filtration System itself or the included remote control.
The remote control has a LCD screen that provides
graphical representations of the various functions and
settings.
The Powermatic PM1200 Air Filtration System has three
speed ranges – Low (547 CFM), Medium (706 CFM) and
High 1196 (CFM). This range of operating speeds lets you

set the Powermatic PM1200 Air Filtration System for the current conditions allowing you to save
energy whenever possible.
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

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.
