Chicopee Engineering takes a practical approach to filter design and construction. A separator that holds its shape under pressure will maintain the maximum filtering surface area for improved performance. It's rigid construction helps maintain more even pressure differentials keeping the filter from collapsing and shutting down your compressor. The Chicopee Separator design utilizes a unique media configuration and innovative structural integrity components to achieve exceptionally efficient oil removal. With less than 3 PPM oil carry-over as a consistent standard, compressors perform better, use significantly less oil and last longer with a Chicopee Separator.
