Class Information
Number: 55/282
Name: Gas separation > With nonliquid cleaning means for separating media
Description: Apparatus having means (1) to apply a nonliquid cleaning agent (gas or solid) to a separator part, (2) to remove separated constituents adhering to the surfaces or from within the interstices of the separating media, or (3) to prevent (in as far as possible) accumulation of constituents on the separating surfaces by some active means or through the use of materials having special characteristics or properties for such purpose.
