Henry Group Industries S-1904 Conventional Oil Separator 3-1/8 in. ODS, 3/8 in. Flare Return

The Henry Group Industries S-1904 oil separator (also called a conventional refrigeration oil separator) removes oil from compressor discharge gas and returns it to the compressor crankcase or oil reservoir. This helps maintain the compressor oil level. It also improves system efficiency by limiting how much oil circulates through the system.

Key Features:

• Top inlet and top outlet design with a 3-1/8 in. ODS refrigerant connection
• 3/8 in. SAE flare oil return connection
• Low pressure drop
• No moving parts within the oil separation zone
• Replaceable float assembly, with a magnet on the oil float to collect debris
• 1/8 in. NPT oil drain
• Shell, end caps and connections made of carbon steel, with a stainless steel oil float
• Maximum working pressure of 450 PSI (31 bar)
• Operating temperature range of 15°F to 300°F (-10°C to 149°C)
• UL and C-UL Listed

How It Works: Oil-laden gas from the compressor enters the separator and passes through an inlet screen, where its velocity drops. Fine oil particles collect into heavier droplets that cling to the screen and the inside wall. The gas then passes through an outlet screen for final separation. The separated oil collects at the bottom, and a float-operated needle valve returns it to the compressor.

Applications: This separator is intended for low-pressure oil management systems. It is used with HCFC and HFC refrigerants and their associated oils. It suits multi-compressor racks and remote condensing units with scroll and reciprocating compressors. It is not recommended for screw or rotary vane compressors.
