Bio-SynXtra™ Super FG Compressor Fluids

(Food Grade H1) ISO-15, 22, 32, 46, 68, 100, 150, 220)

Bio-SynXtra™ Super FG Compressor Fluids are Ultimate Biodegradable2, bio-synthetic compressor lubricants that contain ingredients, which are “Generally Regarded as Safe” (GRAS) for food possessing equipment.  These Food Grade1 lubricants are formulated with biobased synthetic esters to improve lubricity and anti-wear performance for longer service life.  They provide superior lubricating qualities for most compressors, especially portable and stationary rotary compressors (screw and sliding vane) as well as in single-stage, two-stage, and multistage reciprocating compressors (water-cooled and air-cooled), centrifugal compressors, and vacuum pumps.  Their multipurpose performance helps in reducing inventory and lowering cost.  Bio-SynXtra Super FG Compressor Fluids provide excellent anti-rust, anti-foam, and demulsibility properties.  They are highly inhibited against moisture and pass both A and B Sequences of the ASTM D-665 Turbine Oil Rust Test.

Bio-SynXtra Super FG Compressor Fluids have a zinc-free additive system that meets Food Grade H1 requirements. They have shown exceptional anti-wear performance in ASTM D-4172 Four Ball Wear Test and they are recommended for use in vane, piston, and gear-type hydraulic pumps.  The anti-wear performance meets and exceeds the requirements for Denison HF-O, Vickers M-2950-S (35VQ-25) and I-286-S (V-104C), Rexroth, US Steel 126, 136, and 127, DIN 51524 Part 2 and 3, and because they are zinc-free, they  can be used in reduction units where original equipment manufacturers (OEM) require an R&O lubricant (i.e. AFNOR NFE 48-600 HL, DIN 51524 Part 1, and Denison HF-1 fluids).  They also meet the requirements for ashless GL-1, GL-2, and GL-3 gear oils in reduction units and gear sets (Use a Viscosity Sufficient for OEM Application).

Elastomer Compatibility: Bio-SynXtra Super FG Compressor Fluids are recommended for uses with fluorocarbon (Viton), fluorosilicone, polysulfide, Teflon and high nitrile Buna-N (>30%) elastomers. 

Bio-SynXtra FG Compressor Fluids are not recommended for use where neoprene, polyacrylate, polyethylene, natural rubber, styrene-butadiene rubber (SBR, Buna S) or low Buna-N seals are used.

While specific manufacturer recommendations vary, the ISO 32, 46 and 68 grades are most commonly used for rotary compressors, while higher viscosity grades are preferred for reciprocating units.

Maximum oil change intervals can be obtained through proper maintenance and RLI’s oil analysis program. Under good operating conditions and oil analysis program, ISO Grades 32, 46, and 68 could extend service life up to 12,000 hours in rotary screw compressors.

Multi-Applications:  Hydraulic systems, gear drives, gearhead motors, drip oilers, air-oilers, air-tools, water pumps, bearings, machine oil, roller chains, cables, light circulating oil, etc., and general lubrication.

ISO Viscosity Grades 32, 46, 68, and 220 meet and exceeds “Military Specifications DOD-L-24651 Lubricating Oils, Food Grade, and Food Processing Equipment.”  This specification is approved for use by the Departments and Agencies of the U.S. Department of Defense.  ISO Viscosity Grades 32, 46 and 68 meet DOD-L-24651 Type I and ISO Viscosity Grade 220 Meet DOD-L-24651 Type II for general purpose and gear oil lubricants.  This specification also requires a rating of USDA H-1 for incidental food contact.
