Specification_1.docx

This is a Specification document for compressor lubricant oil required to meet strict performance standards for use with Atlas Copco oil-injected screw compressors. The specification calls for Atlas Copco Roto-Xtend Duty Fluid, Part Number 1310-0368-39, supplied in 55-gallon drums or an approved equivalent product. The oil must meet precise technical requirements including a density of 0.843 kg/dm³ at 15 degrees Celsius, kinematic viscosity of 46 mm²/s at 40 degrees Celsius with a viscosity index of 133, water separability of 40/40/0 at 54 degrees Celsius within 15 minutes, and zero foam stability ratings across all three test stages per ASTM D 892. Additional performance criteria include a total acid number not to exceed 0.14 mg/KOH/g, FZG fail stage of 12, rust protection per ASTM D 065B, and a pour point of -57 degrees Celsius.

The specification explicitly requires compatibility with the Atlas Copco GA315W-125 oil-injected screw compressor model and includes a comprehensive list of nine previously evaluated incompatible oils that must not be used as substitutes. These include products from major manufacturers such as Amsoil, Chevron, Mobil, Shell, Schaeffer, Torco, and Phillips 66 Lubricants, with Chevron Hypersyn 46 noted as causing foaming and overheating issues. This specification is associated with Pre-Solicitation opportunity 140RR027Q0025 for compressor lubricant oil.
