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 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. To make it easier to maintain, the PM1200 uses 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 perio
