The BUSCH VACUUM 532.222 is an aftermarket vacuum pump exhaust filter replacement for oil-lubricated vacuum pumps. Its job is to separate suspended lubricating oil from gas leaving the pump, helping retain oil in the separation system rather than discharge it through the exhaust.
For proper service, confirm the replacement part number and inspect the sealing surfaces before installation. Follow the equipment manufacturer’s instructions for separator replacement and oil system maintenance.
