Oil-free compressors used in garages, medical facilities, construction sites and industrial facilities around the world power tools, machinery and inflate tires, toys and boats. Oil-free air compressors used for small shop use tend to be lighter and more mobile, but are noisier than an oil-filled compressor. Industrial oil-free compressors range from one horsepower to over 600 and are capable of powering entire manufacturing lines with a single unit.
Reciprocating, rotary screw and rotary centrifugal are the three primary types of oil-free compressors on the market and each has its place in business applications. When your business relies on compressors, you want the best oil-free compressor for the job at the best price. When it's time to purchase a new oil-free compressor, consider the following:
1. Choose a reciprocating compressor for on-site, mobile oil-free compression applications.
2. Look to rotary screw oil-free compressors for large industrial applications.
3. Fit your constant pressure requirements with a centrifugal oil-free compressor.
4. Get more compressor for the money with used oil-free compressors.
Choose reciprocating oil-free compressors in portable tool driving situationsReciprocating oil-free air compressors come in single and two stage units. Single stage oil-free compressing is normally limited from 70 to 100 psi while two stage compressors can go as high as 250 psi. Reciprocating oil-free compressors excel for portable and short burst applications.
Use rotary screw oil-free compressors for long line, high-pressure environmentsRotary screw oil-free compressors use multiple rotating screws and are externally cooled, which eliminates the need for lubrication. An oil-free screw compressor is capable of industrial pressure levels while providing a true oil free air for medical, painting and large facility applications.
Add centrifugal oil-free compressors to your operation when steady, consistent pressure is requiredCentrifugal oil-free compressors get their power from rotating impellers that transfer energy to air flow. These units work well for high pressure and storage applications because they run continuously to recharge tanks and air feed lines. Centrifugal units are true oil-free designs with the lubricated motor separated by shaft seals and atmospheric vents.
Purchase used and refurbished oil-free compressors and save on costOil-free compressor manufacturers build their units for long life, which makes a used or refurbished oil-free compressor a safe, and money saving purchase. Refurbished oil-free compressors are tested and repaired to work as good as or better than new.
- Oil-free compressor companies design units to fit specific pressure needs and applications. Ensure the compressor your business purchases matches the manufacturers intended use and specifications.
