For increased efficiency and... Energy savings
Two types of oil separators, for either single or multiple (parallel) compressor systems. All of these separators are
hydrogen copper brazed and pressure tested to assure cleanliness and reliability.

Description
48-8310
Oil separator solenoid & relay kit.
Electric Float Oil Separators
The oil separators listed below contain an internal electric float switch to provide the direct
return of oil to the crankcase of single compressor systems or the oil reservoir. The float
activates a solenoid in the line through a relay (Solenoid & relay kit
48-8310
available
separately, see below). Because of the completely open or closed position of the solenoid, the
separator provides positive return of oil, unlike needle valves which clog if the oil is dirty or thick.

Note
: Before installing the oil separator add an initial charge of at least 21.3 oz. of the same type of oil as in the compressor to allow for the amount of
oil it will hold in the sump.
Note
: Solenoid & relay not Included

Oil Separator Solenoid & Relay Component Kit
The oil separator with an electric float requires a solenoid with a maximum operating pressure
of 300 psi & 120 volt SPDT latching relay with a minimum amperage of 2 amps to complete
the oil separation system. For easier selection & installation, this package supplies the proper
solenoid & relay combination with instructions and schematic.
