Powermatic PM1200 - Manual

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
