EnviroAire Oil-Less Air Compressor
When you choose an oil-less EnviroAire Series compressor from Gardner Denver, you get a clean, reliable and efficient air supply that benefits both your business and your bottom line!
Gardner Denver EnviroAire Series: A Superior Choice
The EnviroAire’s 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.
The EnviroAire’s unique design features ensure reliable trouble-free operation and superior performance.
Utilizing the industry’s most proven components, EnviroAire oil-less rotary compressors are not only reliable, but highly competitive. All EnviroAire 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
For sensitive applications in which oil contamination is extremely costly, EnviroAire water-injected rotary screw compressors are the true oil-free solution. Unlike many other “oil-free” compressors, EnviroAire packages contain absolutely no lubricating oil.
