QOF 2-30 hp Oil-Free Scroll Compressors 
Class Zero represents the best air quality possible. In critical environments, it is essential that the compressed air is 100% oil-free. Contamination by even the smallest quantities of oil can cause costly production down time and product spoilage, resulting in product recalls and loss of reputation. The new Quincy QOF 2-30 oil-free scroll compressors meet the Class Zero standard and also provide top class performance, premium efficiency and quality. Outstanding reliability, low maintenance and operating costs make oil-free compressors a sound investment.
WIS 20-75hp Oil-Free Water Injected Screw Compressors
WISAIR’s water injected screw offers the most innovative oil free technology and improved energy efficiency thanks to the superior cooling capability of water. Removing the wasted energy that heat represents gives more air per kW of power. The low temperatures of the compressed air reduces the stress on components ensuring long life. the WISAIR range is certified to ISO 8573-1 Class 0.
At the heart of the wisAIR, there is the water-injected screw airend producing highly efficient near isothermal compression. The polymer ceramic rotors with their optimized rotor profile are supported by water-lubricated bearings, ensuring that no oil contaminates the compression element, thereby producing pure oil-free air. The wisAIR comes standard with an advanced graphic controller. Configurations include air and water-cooled versions, multiple pressures and an optional integrated dryer.
