Oil-Less Air Compressor
When you choose our oil-less air compressor from, you get a clean, reliable and efficient air supply that benefits both your business and your bottom line!
Details of the oil-less air compressor
For sensitive applications in which oil contamination is extremely costly, our water-injected rotary screw compressors are the true oil-free solution. Unlike many other "oil-free” compressors, our packages contain absolutely no lubricating oil.
Established and proven single-stage compression element
Significantly fewer moving parts means fewer wear items
Simplified construction with no inter-stage or final air coolers
Lower speeds and balanced bearing loads extend the compression element service life
Dependable direct-drive system
Cooler operating temperatures reduce component wear
No oil or oil laden parts to dispose of, saving time and expense
Robust Design
Our unique design features ensure reliable trouble-free operation and superior performance.
Utilizing the most proven components, our oil-less air compressors are not only reliable, but highly competitive. All the compressors feature durable, twin gate rotors and a single stage direct driven compression element that was designed for water injection. By using a water-injected design, the gearbox is eliminated which means there is no need for oil lubrication and zero chance of contamination.
Benefits of superior design
Water injection allows for lower temperature rise which eliminates the need for a final air cooler and reduces pressure losses
No metal to metal mating parts and low pulsation levels ensure low vibration and noise levels
Sealed grease-lubricated main rotor bearings and water-lubricated gate rotor bearings extend rotor and bearing life
High efficiency water purification system filters the injection water entering the compressor to maintain a high water purity level and ensure reliable and trouble-free operation
Performance of the oil-less air compressor
The unique water-injected, variable speed design achieves lower speeds combined with lower operating temperatures—resulting in high efficiency and reduced component wear.
Water Injection means lower temperatures, and lower temperatures mean more efficient compression.
Accessories of the oil-less air compressor
Just as vital as setting up the correct compressed air system is keeping that investment well maintained. By using our approved air treatment and aftermarket parts and accessories, you can make sure the health of your system is maintained.
