Universal Flange Oil Regulators
MAXIMUM WORKING PRESSURE: 450 and 675 PSIG
Features
Oil regulators control the oil level in the compressor crankcase through the use of a float-operated valve.
The RG-4 has a universal flange, capable of mounting directly to both Copeland and Bitzer compressors, eliminating the need for adapter kits and reducing the cost of installation. For other compressor configurations, adapter kits can be used to convert the universal mount to non-standard compressor mountings.
The oil feed connection is a standard 3/8″ SAE flare. A 1/4″ SAE flare oil equalization connection is also provided, placed at the 1/2 glass* range

OIL FILTER
We recommend filtering the oil prior to reaching the oil regulator to prevent debris or contaminants from obstructing the float valve. Our oil filters can be used to accomplish this filtration.
