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.
Meets ACGIH/ISO/CEN respirable convention
- 4.0-µm 50% cut-point at a 2.75 L/min flow rate*
- 3.5-µm 50% cut-point at a 3.7 L/min flow rate† for alternate applications
Eliminates adverse electrostatic effects
Tangential inlet design decreases particle losses due to impaction
Eliminates ambient wind speed and orientation effects
Overcomes electrostatic effects experienced with the Dorr-Oliver Cyclone
Conductive plastic is safe for underground mine use
