Air filter device

摘要: PURPOSE: To obtain the air filter device which is inexpensive and has small flow resistance. CONSTITUTION: This an electrostatic 5, electrodes 7, 9 for applying a voltage to this 6 in contact with these electrical conductivity above-mentioned electrode formed of metallic wires or having and, therefore, use materials omission are possible. The thus obtd. In addition, extremely fine possible resistance degradation filtration function by minimized. COPYRIGHT: (C)1992,JPO&Japio
