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 
The inner and outer filter elements (left) can be removed or installed (right) 
without tools. 
 
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
