The Multiple-inlet GS-3 Cyclone
The GS-3 Cyclone is a 10-mm lightweight conductive plastic unit used with a standard three-piece cassette with filter for the collection of respirable dust particles. The GS-3 Cyclone’s removable cassette adapter fits securely into the middle ring of the filter cassette during sampling. Designed to meet the ACGIH/ISO/CEN respirable convention, the GS-3 Cyclone has a 50% cut-point of 4 µm (bias within ISO/NIOSH requirements) at 2.75 L/min* or 3.5 µm at 3.7 L/min† for alternate applications.
