Stage 3: HEPA filter captures fine particles/smoke
For applications that generate very fine particles or smoke, or when workers are directly exposed to discharge air from the collection system, a HEPA filter is recommended. With a rated efficiency of 99.97% on 0.3 micron particles, this is the final step to filtration performance excellence.
Cross-flow filter design for better drainage means longer filter life. Dirty air flows horizontally through the walls of the filter in the WSOFlex, perpendicular to drainage of collected and coalesced mist.
This design promotes optimum drainage, which extends filter life and returns collected coolant for re-use. Conventional mist collectors have an upflow design impeding drainage and causing short filter life.
