What is an Oil-Less Compressor?

An oil-less compressor, also referred to as an oil-free air compressor, does not use oil for lubrication. This type of compressor operates at a lower RPM than a lubricated unit, which makes it quieter and more energy efficient over the course of its service life.

What is the Difference Between Oiled and Oil-Less Compressors?

Straight Piston Oil-Less Compressors, also known as Reciprocating Air Compressors, differ from oiled compressors because they do not require oil to function. An oiled air compressor is ideal for applications that require high pressure and volume. Oil needs to be added to the compressor to allow for higher RPMs and it keeps the compressor running at high speed. An oil-less air compressor does not require oil and it is lighter weight and portable. This oil-free compressor is optimal for applications where noise and air quality are a concern.

Benefits of the Oil-Less Compressor Technology

Oil-less air compressor technology offers measurable advantages over lubricated alternatives across a range of professional and industrial settings. Key benefits include:

• Cleaner Air Output
• Reduced Maintenance Requirements
• No Oil Contamination Risk
• Energy Savings
• Long-Term Reliability
• Compliance With Strict Air Quality Regulations
