ISO 32 Air Compressor Oils

ISO 32 compressor oil is used in selected rotary screw and reciprocating air compressors, industrial compressor systems, and certain refrigeration applications. The catalogue includes oils for moderately severe and severe operating conditions, food-grade applications, and systems using specific refrigerants. Always match the lubricant’s chemistry, compressor type, refrigerant compatibility, and OEM specification to the equipment requirements.

No. ISO viscosity grade alone does not determine suitability. The products listed include formulations intended for rotary screw, reciprocating, piston, vane, gas, refrigeration, and food-grade equipment. Check the compressor manufacturer’s specification and the replacement product’s compatibility information, including base-fluid chemistry and any stated OEM-equivalent match, before changing lubricant.

Available formulations include full-synthetic, partial-synthetic blend, mineral, PAO, PAG, POE, diester, alkylbenzene/mineral, and silicone-based products. The range also includes non-toxic or non-hazardous formulations and NSF H1 options for applicable food-processing environments. Formulation choice should follow the compressor design, operating conditions, existing lubricant, and required approvals.

Yes. The category includes ISO 32 refrigeration lubricants for systems using HFC, CFC, HCFC, blended refrigerants, and ammonia R717, depending on the individual product. POE, PAG, alkylbenzene, and other chemistries are represented. Refrigerant compatibility and lubricant miscibility are application-specific, so confirm the exact refrigerant and compressor requirements before ordering.

Many listed products are described as 100% OEM compatible, OEM-equivalent, or meeting or exceeding OEM specifications. Some are direct replacements for named lubricant brands or compressor fluids. Compatibility claims apply to the specific product and cross-reference, not automatically to every ISO 32 oil, so provide the compressor model, current lubricant, and operating conditions for technical confirmation.

Packaging varies by product and includes quart containers, gallon cases, five-gallon pails, 55-gallon drums, 275-gallon totes, and 330-gallon totes. Some single-product replacement fluids are offered in a specific container size. Contact US Compressor to confirm current packaging, availability, pricing, shipping details, and return requirements for the selected lubricant.
