Special Applications


Due to constant evolution of compressed air tools, machineries and processes, some applications require the use of compressed air totally free of oil.

Food and beverage industry, white rooms, laboratories, hospitals are typical examples.


WIS can fulfill these oil free requirements and can also basically replace any oil lubricated installation with extra benefits:

  • Peace of mind – no contamination risk by oil.
  • Low maintenance – no line filters regular exchange required.
  • Energy saving – no extra consumption linked to pressure drop through the filtration installation.
  • Protection of the environment – no polluted condensate and no cost for their treatment.
  • WIS® – are class 0 certified and ensure you the best quality of air.

WIS® Technology

WIS® compressors, thanks to water lubrication properties have a low air temperature increase that allows high energy efficiency.

They integrate a standard Reverse Osmosis system, which plugged to tap water, refills the main water flow when required with a water free of mineral, sediments and bacteria.

Specific components also equipped the WIS® to avoid premature wear linked to water aggressivity, stainless steel water tank and filter housing, brass couplings and connections, Aluminium/Bronze alloy screw element housing, and polymerized ceramic rotors.

All WIS® are controlled with a sophisticated electronic controller that allows extended communication capability, including room control of up to 4 WIS® (optional).

Available in Air Cooled, Water Cooled, Integrated Dryer & Energy saving Variable Speed Drive(VSD) Variants.


The continuous innovation of the compressed air tools and machineries, the evolution of specific productive processes and uses, require exclusively air without oil.

It is easier and less hazardous to produce non-lubricated compressed air than to de-oil the compressed air contaminated by oil using more or less complicated filter assemblies.

A new compressor with innovative features, reliable, compact, noiseless and capable of producing compressed air without oil. A double spiral without contact among the parts for an innovative NON-lubricated compressor.

Super-silenced, non-lubricated compressor


It covers a series of power range from 2 to 5 kW

Particularly suitable for installations close to use points, with direct association to the using machine, or as extension of an existing plant.

SUPER version: Structurally it is like the Skid version with super-silencing cover and with command and control panel.

SUPER DRY version: It is made up of compressor, as in version Super, with embedding within the same structure of a dryer with an ecological refrigerating cycle with gas R134a and indicator of the dew point.

Super-silenced, non-lubricated multiple compressor.

It covers a series of power range from 8 to 20 kW.

Used in applications where the consumption of compressed air can be very variable, or where there is the need to have a stock always available.

SUPER MULTI version: it is made up of two or more “Super” compressors integrated in a single structure. SUPER MULTI DRY is made up as the previous one, with embedding in the same structure of a dryer with refrigerating cycle, as above. 

Nitrogen Generators

All nitrogen generators are not created equal. Some may cost less and appear great on the outside. Look closer and we think you’ll agree that we offer a superior product, greater durability and a better overall value.
