The lightweight 10-mm single-inlet GS-1 cyclone is an equivalent design to the 10-mm nylon cyclone. The advantage is its conductive plastic construction that eliminates the electrostatic effects of the non-conductive nylon cyclone making it safe for use in underground mines.
About GS-1 Cyclone Flow Rate
The GS-1 Cyclone is designed for use with the SKC DPM Cassette at 1.7 or 2 L/min and for respirable dust sampling to meet the ACGIH/ISO/CEN respirable convention with a 50% cut-point of 4.0 µm at 2 L/min.

|Using the GS-1 Cyclone with the SKC DPM Cassette |
The SKC DPM Cassette with built-in precision-jeweled impactor is designed for sampling in atmospheres where it is necessary to differentiate diesel particulate matter from other respirable dust (such as coal dust) based on particle size. The built-in impactor screens out respirable particles = 1.0 µm; particles less than 1.0 µm collect on the heat-treated quartz filter. The GS-1 Cyclone can be used with the DPM Cassette to prevent the impactor from clogging in atmospheres where larger particles (> 4 µm) may be present as recommended in NIOSH Method 5040.
