Oil-free compressors

Oil-less or oil-free compressors are compressors that don’t use oil. They’re the top choice for dentists, orthodontists, hospitals, salons, air suspension vehicles, food processing plants, chemical companies, and more. They’re even gaining in popularity.

So, how does a compressor without oil work?


All joking aside, compressors typically have a coating, such as Teflon, to keep the rotors moving smoothly without oil lubrication. In Kaeser’s case, the company uses blasted and bonderized rotors with a special coating process. These rotors are durable, resisting temperatures up to 575°F. Because this coating is highly abrasion-proof, its sealing and protection performance remain consistent — even after years of operation.

Why oil-free compressors?

Because they don’t contain oil, the machines are great options for healthcare needs such as oral surgeries where air quality matters. Kaeser’s dental compressors are small, efficient, and produce low noise levels. Kaeser oil-less compressors provide consistently clean and high-quality air, and with multiple sizes available you have more placement options for your business. In fact, air quality control for pharmaceutical, food, beverage, and chemical industries — which are heavily regulated — could benefit from a compressor without oil. There may be incentives to going oil free in your industry.

But air quality isn’t the only reason to get oil-free compressors. Plants or places that need energy-efficient operations could benefit. According to Kaeser Compressors, capital expenses and maintenance costs account for only a small part of a compressor’s total life cycle expenditures. Energy is typically the largest expense when it comes to compressors, so any efficiency saves money.

In addition, the oil-free compressor is easier to maintain and requires less maintenance. Kaeser indicates that fewer wearing parts and premium quality materials ensure reduced maintenance requirements, longer service intervals, and extended service life. Since the compressor doesn’t need oil tested or changed, that’s also an expense that’s eliminated. And large doors make it easier for a technician to assist in maintenance or repairs. That could mean fewer hours in total to service your compressor, even when it does need maintenance or repairs.

Kaeser makes a mobile oil-free compressor to use on the go, wherever you are. That could be handy in construction and other jobs where compressors need to go with you. Some authorized dealers even enable you to rent this equipment.
