The GS-3 Respirable Cyclone is operated at 2.75 L/min to conform to the ISO 7708/CEN criteria specified in the 2016 OSHA rule on respirable crystalline silica. The SKC GS-3 Cyclone’s multiple tangentially arranged inlets eliminate ambient wind speed and orientation sensitivity and decrease particle loss due to impaction. Lightweight conductive plastic construction eliminates electrostatic effects. The GS-3 Cyclone is used with a standard three-piece filter cassette.
Features
