Oilless air compressors have long ring life
PureAir and PureAir II series of oil-less air compressors are available in many configurations, including multiple packages that meet NFPA99 guidelines. The line ranges from 5-15 hp and features a totally dry crankcase. A coated piston head isolates the piston, rings, and connecting rod bearings from the full heat of compression, increasing ring life up to 10,000 hr.
