The SKC Aluminum Cyclone is a lightweight respirable dust sampler that is used with a filter loaded into a three-piece filter cassette. The cyclone separates dust particles according to size. The respirable particles collect on a filter for analysis while larger particles fall into the grit pot and are discarded.

The SKC Aluminum Cyclone is specified in NIOSH methods for silica and respirable dust. The Aluminum Cyclone is operated at 2.5 L/min to conform to the ISO 7708/CEN criteria specified in the 2016 OSHA final rule on respirable crystalline silica and meets ACGIH respirable TLVs.
