WIS^® compressors, thanks to water lubrication properties have a low air temperature increase that
allows high energy effi ciency.
They integrate a standard Reverse Osmosis system, which plugged to tap water, refi lls the main water
flow when required with a water free of mineral, sediments and bacteria.
Specifi c components also equipped the WIS^® to avoid premature wear linked to water aggressivity:
stainless steel water tank and fi lter housing, brass couplings and connections, Aluminium/Bronze alloy
screw element housing, and polymerised ceramic rotors.
