Some effects of charging on 10-mm nylon cyclone performance.
Am Ind Hyg Assoc J 1974 Oct; 35(10):603-612
The effects of static charge in relation to the efficiency of 10- millimeter cyclone perfilters for dust samplers are studied using a specially constructed calibration chamber. The average coefficient of variation for four types of 10-millimeter cyclones is found to be approximately 10%. Differences appear to be caused by electrostatic fields resulting from excess charge deposited on the surfaces of the dielectric cyclones tested. An inexpensive, lightweight, conductive material is indicated as desirable for cyclones in place of heavy and expensive though most efficient stainless steel cyclones.
