AGMA 7 S Synthetic Gear Lube is a multipurpose, synthetic circulating oil developed for use in a wide variety of industrial applications. The lighter viscosity grades (ISO 32, 46, 68 and 100) typically are recommended for use in rotary air compressors, circulating pumps, vacuum pumps and electric motor bearings operating under severe-service conditions or at extreme temperatures. The heavier viscosity grades (ISO 150, 220, 320, 460 and 680) typically are recommended for use in lightly loaded gearboxes that do not require an extreme-pressure gear oil. The medium viscosity grades (ISO 150 and 220) also are recommended for lubrication of the upper cylinders of gas compressors handling natural gas or process gas.
