The oil separator installed on the discharge line of the compressor intercepts the oil mixed with compressed gas and returns it to the oil receiver or directly to the compressor crankcase thus assuring an efficient lubrication of its moving parts.
Furthermore, the oil separator maintains a high coefficient of condenser and evaporator performance by almost completely removing oil deposits from their exchange surfaces.
Separators series 55/56 are closed type and they cannot be dismantled from the system, except cutting the piping
