Air Compressor Oil

When it comes to air compressor oil, there are two main types , mineral oil and synthetic oil Using the right oil for the air compressor is crucial. Good designed compressor oil must be infused with optimal viscosity and additive balance that provides reduced energy consumption, protection against friction, and ensures maximized compressor lifespan.

Air compressor oil is used to lubricate both the working parts and the pressurized spaces in a compressor. The purpose of the lubricant in the pressurized section is not only to reduce friction and wear but also to improve sealing of the pressurized spaces and to provide cooling. For Reciprocating Compressors a lubricant is required for the bearings, pistons, rings, cylinders and valves that has enough antiwear additives and suitable viscosity .The pistons and valves reach temperatures of 2200C to 3000C and the oil film on the surfaces of these components must not form soft and hard carbon. Good demulsibility properties are also necessary to aide water/oil separation as the oil containing air is cooled and the water vapor condenses.

In case of screw compressors that are either geared or non-geared type require good lubrication of the rotors as well as the bearings and gears and the oil must have excellent resistance to oxidation , low foam , good air release and antiwear characteristics. Low foam and good air release are also important otherwise excessive foam will form in the receiver and significantly increase oil carry over.

FAQ Air Compressor Oil

Air Compressor Oil is used to lubricate, cool, clean, and protect compressor components while reducing friction, wear, oxidation, corrosion, deposits, and operating temperatures during continuous service.

Mineral compressor oil is generally an economical choice for standard operating conditions, while synthetic compressor oil is designed to provide improved oxidation stability, temperature performance, and potentially longer service intervals under demanding conditions.

The correct viscosity grade depends on the compressor design, operating temperature, load, and manufacturer's lubrication requirements, with ISO VG 32, 46, 68, and 100 being common commercial grades.

No, compressor oils are formulated for specific equipment and operating conditions, so the lubricant should be selected according to the compressor manufacturer's recommended specification and the requirements of screw, reciprocating, rotary vane, or other compressor systems.

You can find suitable Iranian suppliers and manufacturers of Air Compressor Oil through Irancorps, which helps international buyers connect with Iranian manufacturers and exporters offering industrial lubricants and related products.

Air Compressor Oil should be kept in tightly sealed original containers in a clean, dry, and well-ventilated storage area away from direct sunlight, excessive heat, water, dust, and chemical contamination.
