Use aluminum cyclone with three-piece loaded air sampling cassettes to separate and remove larger particles from the respirable dust. The cyclone allows respirable dust to collect on the filter membrane while larger particles fall into the grit pot. Meet the standards set forth by ACGIH/ISO/CEN for a collection efficiency curve with a median 50% cut point of 4 μm at 2.5 L/min using the cyclone. Cyclone starter kit includes cyclone, holder, O-ring, and grit pot. Simply add a 25- or 37-mm air sampling cassette to start filtering for respirable dust. Cyclone requires both a cyclone holder and a three-piece loaded air sampling cassette. Clip the cyclone to a shirt collar or pocket as close to the breathing zone as possible. Sampling pump can be clipped to a belt or placed in a protective pouch. Separate and remove larger particles before collecting on sample media Meets the standards set forth by ACGIH/IOS/CEN/NIOSH Static conductive aluminum eliminates interference Compact and lightweight?only weighs 1 oz (30 g) Fully interchangeable with SKC aluminum cyclone Requires a cyclone holder and a three-piece, 37-mm diameter air sampling cassette
