Activated carbon compressed air purifier Class 35

floor-standingfilterdust

Product Overview
Class 35–800 threaded compressed air filters are intended for main-line and equipment-inlet filtration. A smooth 90° inlet path and conical flow diffuser reduce turbulence and pressure loss while increasing the effective filtration area. The three-section housing enables quick filter-element replacement and straightforward drain maintenance.
