GRASSAIR
WIS® Series Water Injected Oil-Free Rotary Screw Compressors
GRASSAIR WIS ® Series Water Injected Oil-Free Rotary Screw Compressors are the simplest and most efficient of all oil-free compressors available in the market today. These units use water as a coolant instead of oil, resulting in Isothermal Compression, the most efficient way to compress any gas. Energy savings in the range of 10-40% are achievable, compared to other compressors. Single stage design with Ceramic Rotors, Single Water-cooler replacing the conventional inter, after and oil coolers, V-belt drive, and Microprocessor based control make these units the best choice.
