Conductive Cyclone Nylon 10mm 1.7LPM by Zefon Plan:4 Day we also have the GeminiThe Zefon 10mm Conductive Nylon Cyclone (a static conductive replica of the 10mm Dorr Oliver Nylon Cyclone) is used in conjunction with 37mm filter cassettes to separate dust particles by size with the respirable particles being collected on the filter and larger particles being removed. The collection efficiency curve meets the standards set forth by ACGIH ISO CEN for a respirable curve with a median 50% cut point of 4 when operated at a flow rate of
