The Chicago Pneumatic (CP) Screw Compressor Air Oil Separator is a precision-engineered filtration component designed to extract atomized oil from the compressed air stream in CPB, CPC, and CPD series rotary screw compressors. Utilizing advanced multi-layered coalescing media, these separators ensure minimal oil carryover—typically less than 3 ppm—which guarantees high-quality discharge air and prevents lubricant contamination of downstream pneumatic equipment.
