What is rotary screw air compressor oil?

Air compressor oil plays several vital roles within a rotary screw air compressor system: Rotary screw air compressors are sometimes “oil flooded” or “oil injected,” describing that oil is injected into the rotor housing. The oil mixes with the air during compression but is separated back out before the compressed air leaves the system.

What is air compressor oil?

Air compressor oil is standard or synthetic oil made specifically for air compressors. Unlike motor oil, air compressor oil does not contain detergent and typically has lower amounts of carbon, sulfur, and other contaminants that can cause build-up.

How does an air compressor lubricant valve work?

When the air compressor is first started, and the oil is cold, this valve will direct our oil straight into the airend and bypass the oil cooler. This will ensure the lubricant heats up quickly and can effectively perform all the tasks we demand of it.

Do flooded rotary screw air compressors need lubricating oil?

The principles and importance of clean, warm lubricating oil are the same for all flooded rotary screw-type air compressors, so though there may be a variance on the operational order in your air compressor, the principles and required components remain the same.

Which air compressor oil should I use?

Manufacturers who don’t specify an exact oil brand may still recommend a 20-weight or 30-weight non-detergent oil. 20-weight oil is typically used in colder environments, while 30-weight oil is better suited for warm climates. Some operators will switch between these oils for the summer and winter seasons. When should I change air compressor oil?

What is the difference between motor oil and air compressor oil?

Unlike motor oil, air compressor oil does not contain detergent and typically has lower amounts of carbon, sulfur, and other contaminants that can cause build-up. Generally, rotary screw air compressors use synthetic oil, while recreational compressors may use standard oil.
