A refrigerant recovery apparatus has features for trapping oil recovered from an air conditioning system. It has a low pressure oil separator which is mounted in line with the flow of refrigerant on the suction side of the compressor. The low pressure oil separator will be located at a lower elevation than the compressor. When the compressor is turned off, this allows excess oil in the compressor to drain to its design level.
