Robinair Discharge Oil Coalescing Filter separates oil from vapors in the discharge gas stream so it can be returned back to the compressor. This filter can become plugged when a compressor fails from a burn out or overheating due to waxes normally found in refrigerants. If you are replacing the compressor in your recovery unit, we suggest you also replace this filter. (Does not include sealing O-ring 123785 or canister seal 123786)
