Project Description

Pre Filter

W-PRE radial wedge pleat is with the greatest media area exposed to the air flow which can contribute filter’s dust collection capacity. W-Pre Disposable Pleated Air Filters are available in a wide range of sizes; and with slight or without any system modification, is able to fit most commercial and industrial installations. Only need to use gaskets and fasteners to adapt W-PRE filter to existing filter bands.
