Petro-Canada recently augmented its extensive line of food-grade lubricants, greases and specialty fluids with the PURITY FG synthetic compressor fluid—a polyalphaolephin-based product formulated with selected additives.

While upholding operational performance across a wide temperature range, the PURITY FG further delivers:

  • Accommodations to the highest food industry safety standards, including NSF registration as an H1 lubricant.
  • Compliance of all components with FDA regulation 21 CFR 178.3570 regarding lubricants with incidental food contact.
  • Protection against wear, oxidation, rust and corrosion.
  • Application in hazard analysis and critical control point, as well as good manufacturing practice plans.
  • The power to perform in wet food-processing environments.
  • Suitability for lubricating air screw and centrifugal compressors; vacuum pumps; equipment in pneumatic, hydraulic and circulating applications; and gearboxes used in food-processing operations.

“A common concern related to the use of food-grade compressor fluids is that they don’t perform as well as non-food-grade lubricants, and, more specifically, they cannot withstand high temperatures and perform throughout tough food-processing applications,” according to Colleen Flanagan, Petro-Canada’s specialty fluids category manager.

“Performance should never be compromised, and we feel that our PURITY FG synthetic compressor fluid is the lubricant solution that many maintenance managers have been waiting for. It provides a number of performance benefits [that] our customers want and need, including enhanced thermal and oxidative stability, extended fluid life and wide temperature performance.”

Research and development product specialist Larry Curts adds that the “PURITY FG synthetic compressor fluid performed extremely well throughout Petro-Canada’s comprehensive testing process, further validating the product’s performance benefits. One of the more notable tests included RPVOT ASTM D2272 resistance to oxidation. The PURITY FG’s minutes to oxidation was 4,554, compared to competitive synthetic products with minutes to oxidation ranging from 1,129 to 2,364.

“Other performance data collected included a viscosity index of 134 (using the D2270 test method), a four-ball wear of 0.40 mm (using the D4172 test method) and a four-ball weld of 126 kg (using the D2783 test method). Our customers rely on us to provide them with a full line of food-safe and plant-tough lubricants that outperform the competition.” Flanagan continues, “They also rely on us to continue to innovate and formulate lubricant solutions based on their ever-changing needs.”
