PURITY™ Food Grade Compressor Fluids


PURITY Food Grade Compressor Fluids are formulated with SynFX™, an advanced additive technology designed to deliver synthetic-like performance and long lasting protection.

As conditions in food plants become more demanding, so must the lubricants that keep the equipment running. Wet/humid processing environments, high air volume, and high discharge temperatures are just some of the challenging service conditions compressor oils must endure.


PURITY™ FG’s outstanding performance results from more than 30 years formulating experience. Using the HT Purity Process, Petro-Canada Lubricants’ produces a 99.9% pure, crystal clear base oil – among the purest in the world.


Virtually free of impurities that can hinder performance and fortified with specially selected performance additives, PURITY FG Compressor Fluids provide outstanding resistance to oxidation.


Purity FG Compressor Fluids also meet the highest food industry safety standards and can be easily integrated into HACCP (Hazard Analysis and Critical Control Point plans and GMP (Good Manufacturing Practice) programs. All fluid components comply with U.S. FDA 21 CFR 178.3570 Lubricants with incidental food contact. All fluids are H1 registered by NSF. They are certified Kosher and Halal.

Features & Benefits

  • Resists oxidative breakdown better than leading specialty food grade compressor fluids

    • Better resistance to oxidative decomposition caused by exposure to air at high discharge temperatures.​

    • Reduced oil thickening which can improve compressor efficiency

    • Up to 4,000 hours service life in rotary screw compressors (85°C/185°F)
