Frequently asked questions
Common questions about PETROCHEM from 3G Electric.
What ISO viscosity grades are available in PETROCHEM air compressor oils?
PETROCHEM air compressor oils are offered in ISO viscosity grades 32, 46, and 68, corresponding to SAE grades 10, 15, and 20 respectively. The 32 grade is typically used in rotary screw compressors operating in cooler climates, while 46 and 68 grades suit higher ambient temperatures or vane-type compressors. The viscosity index ranges from 97 to 140, indicating the oil's ability to maintain viscosity across temperature changes. Selection should follow the compressor manufacturer's specified viscosity grade to ensure proper lubrication and avoid excessive wear or energy consumption.
Are PETROCHEM compressor oils available with food-grade certification?
Yes, certain PETROCHEM compressor oils carry NSF H1 or H2 registration. The Petro-Comp FG-40XL series (SKUs 45VG28 and 45VF67) is NSF H1 rated, suitable for applications where incidental food contact may occur. The Airguard 46-005 (SKU 40P266) is NSF H2 rated, intended for use in areas where no food contact is possible. Food-grade oils use base stocks and additives that meet FDA 21 CFR 178.3570 requirements. Always verify the specific NSF rating on the product label before use in food-processing environments.
What is the operating temperature range for PETROCHEM synthetic air tool oils?
PETROCHEM synthetic air tool oils are formulated for wide temperature ranges. The Airguard 46-005 (SKU 40P266) operates from -55°F to 450°F, while the Airline Tool FG-055 (SKU 45VG25) extends from -67°F to 460°F. These ranges cover cold-start conditions in unheated facilities and high-temperature operation in continuous-use tools. The synthetic base stock provides thermal stability and resists oxidation at elevated temperatures, reducing varnish and deposit formation in pneumatic tools.
How do I select the correct PETROCHEM oil for my air compressor?
Selection depends on compressor type, operating temperature, and manufacturer recommendations. For rotary screw compressors, use the ISO viscosity grade specified in the manual—typically 32 for cooler environments or 46/68 for warmer conditions. PETROCHEM's Air-Comp series (ISO 46, SAE 15) is a general-purpose mineral oil. The Syncomp PAO series (ISO 32, SAE 10) uses synthetic polyalphaolefin base oil for extended drain intervals and better low-temperature flow. If food processing is involved, choose the Petro-Comp FG-40XL series with NSF H1 rating. Container size (1 gal, 5 gal, or 55 gal) should match your oil-change volume and storage capacity.
Does PETROCHEM offer synthetic compressor oils?
Yes, PETROCHEM's Syncomp PAO series (e.g., SKU 45VF65, MPN SYNCOMP PAO-32-001) is a synthetic polyalphaolefin-based compressor oil. It has a viscosity index of 126, indicating excellent viscosity retention across temperature extremes. Synthetic oils generally provide longer service life, better oxidation resistance, and improved low-temperature fluidity compared to mineral oils. They are recommended for compressors operating under severe conditions, such as high discharge temperatures or continuous duty cycles. Always confirm compatibility with compressor seals and gaskets before switching from mineral to synthetic oil.
