This Dorr-Oliver cyclone is designed to separate the respirable fraction of airborne dust from the nonrespirable fraction. It consists of a two-stage cyclone and lightweight aluminum frame, which mounts a standard 2 or 3 piece 37mm filter cassette. When air enters the cyclone stage at 1.7 LPM (as recommended by NIOSH), the larger nonrespirable particles are centrifugally separated out and drop into a lower grit pot. The smaller, respirable particles pass onto the cassette, where they are captured by the filter membrane.

• Meets NIOSH requirements for 10mm nylon cyclones, as specified for nuisance dust (#0600) and silica dust (#7500, 7501, 7601, 7602)
• For collection of all types of respirable dust
