Conventional Oil Separators
Low Pressure | MAXIMUM WORKING PRESSURE: 450 PSIG
Features
Our standard screen-style separators remove oil from refrigerant gas using three methods: velocity reduction, screen filtering, and baffling. All separated oil is then returned to the compressor crankcase or reservoir by an internal oil float valve.

Centrifugal Oil Separators
Low Pressure | MAXIMUM WORKING PRESSURE: 450 PSIG
Features
Centrifugal oil separators are designed to remove large quantities of oil at a wide range of operating capacities. Field tests have shown these oil separators are up to 99% effective—even in high oil loading conditions.
Both sealed and serviceable units are available. We recommend serviceable oil separators for use in supermarket and parallel compressor systems.
For screw compressor applications, an oil separator/reservoir without internal float must be used. Contact Westermeyer Industries for more information.

Centrifugal Oil Separator / Reservoirs
Low Pressure | MAXIMUM WORKING PRESSURE: 450 PSIG
Features
This product is designed to remove large quantities of oil at a wide range of operating capacities. Field tests have shown these oil separators to be up to 99% effective—even in high oil loading conditions.
The separator and reservoir are divided by an internal baffle to protect reserved oil from the turbulent action of the separator. Two sight glasses provide visual indication of the oil level. A 3/8″ flare Rotolock valve is included for installation of the oil return port.

All capacities shown based on 90% at 100°F condensing temperature.
In varying-load applications, (ex. supermarkets) please refer to our online sizing tool for adjusted ratings.
Note: These oil separators must be used with an oil pressure reducing valve.
The oil pressure will be the same as discharge pressure.
How To Choose
Select an oil separator based on the system’s tonnage (compressor BTUs) under normal operating conditions. Choose an oil separator with the nearest capacity to the system’s load at the evaporating temperature. Minimum tonnage is 30% of the rated capacity.
For refrigerants and conditions not listed, see our online sizing calculator or contact us for assistance.
Centrifugal Oil Separator / Reservoirs
High Pressure | MAXIMUM WORKING PRESSURE: 675 PSIG
Features
This product is designed to remove large quantities of oil at a wide range of operating capacities. Field tests have shown these oil separators to be up to 99% effective—even in high oil loading conditions.
The separator and reservoir are divided by an internal baffle to protect reserved oil from the turbulent action of the separator. Two sight glasses provide visual indication of the oil level. A 3/8″ flare Rotolock valve is included for installation of the oil return port.

Coalescing Oil Separators
Sealed | MAXIMUM WORKING PRESSURE: 450 PSIG
Features
Our coalescing oil separators use a borosilicate glass filter element designed to be 99.5% effective at removing oil particles and system contaminants above 0.3 microns in size. It is recommended that the oil separator be changed when the pressure differential exceeds 15 psig.
See our parts & accessories page for the RDP-01 Differential Pressure Monitor.

How To Choose
To correctly select the size of oil separator for your application, use the DCFM sizing chart, which is based on nominal evaporating and condensing temperatures.
For refrigerants and conditions not listed, see our online sizing calculator or contact us for assistance.

SIZING CHART
Example of use
Find the DCFM value for the refrigerant being used at the appropriate evaporating and condensing temperature. Then, multiply this value by the system tonnage at the operating conditions. Use this value to select an oil separator with the nearest maximum DCFM value to the calculated DCFM.
Example:
R134A, 20 Tons at 20°F/110°F = 1.02 DCFM
Total DCFM = 20 tons x 1.02 DCFM = 20.40
