99.97 efficiency @ 0.3 micron
The PFB-2500(SP) filtration unit is among the most versatile ventilation systems on the market. High flow capability and up to (4) 8" inlet adapters allow multiple tasks to be performed from a central location. (Unit pictured has a single 12" inlet.) With air flows up to 2500 CFM, a rugged chassis and a highly efficient filter, this compact ventilation unit is the choice for those applications requiring high flow rates, small size and sustained operating capability.
