Cross-Flow Design 

Cross-flow filter design for better drainage for long filter life. Dirty air flows horizontally through the walls of the WSO filter, perpendicular to drainage of collected and coalesced mist. This design promotes optimum drainage, which extends filter life and returns collected coolant for re-use.
