Cyclone use virgal force to separate large parties from the airstraam. Thee separated powder falls into a hopper and can be blended wigh virgin powder at a controlled ratio (typically 70: 30 virgin to recoprim). Cyclone are best for single- color or limited - color operations because the powder is not finely classified - particlee size distribution shifts slightly, so color consistency may degrade over multiple recycles.

Cartridge or bag filter recoprimers capture all parties, including ding fines. They are more compact and are often part of they spray booth 's filtration systeme.
