Bulk Fluid Systems

Many listed products are described as 100% OEM compatible or as meeting or exceeding OEM specifications. Compatibility is product-specific and may depend on the compressor, pump, refrigeration system, lubricant chemistry, viscosity grade, and whether a top-off or complete change is planned. Use the relevant cross-reference information or contact US Compressor for compatibility guidance before ordering.

Refrigeration options cover systems using HFC, CFC, HCFC, ammonia, carbon dioxide, and natural refrigerants such as propane and butane, depending on the product. PAG, POE, alkylbenzene, mineral, and synthetic formulations are represented. Refrigerant compatibility and viscosity must be matched to the equipment and operating conditions before fluid selection.

Yes. The range includes products described as meeting NSF H1 requirements for incidental food contact, including air compressor, refrigeration, gear, and other lubricant applications. Food-grade status is specific to the individual product and intended use. Confirm the required application, viscosity, equipment compatibility, and applicable site requirements before purchase.

Packaging varies by product. Listed options include quart containers, gallon cases, five-gallon pails, 55-gallon drums, 275-gallon totes, and 330-gallon totes. Some individual replacement products are offered in a single specified container size. Confirm the required package configuration and availability for the selected fluid.

Yes. US Compressor provides technical support, lubricant selection guidance, cross-reference assistance, expert blending, and free oil analysis services. To support an accurate recommendation, provide the equipment manufacturer and model, current lubricant name or specification, operating conditions, refrigerant where applicable, and required package volume.

The range supports rotary screw, reciprocating, piston, vane, gas, and refrigeration compressors, along with industrial gear systems, compressor gear systems, hydraulic equipment, mechanical seals, pumps, bearings, and vacuum pumps. The correct fluid depends on the equipment design, lubricant chemistry, viscosity, operating environment, and OEM specification.
