sullivan palatek aqua air water lubricated oilless oil free rotary screw air compressor with dedicated refigerated compressed air dryer

The Sullivan-Palatek Aqua Air is a rotary screw compressor which uses distilled water in place of the oil normally used to cool, lubricate and seal the rotors. This results in lower operating temperatures (11-14ºF above ambient) and gives it the ability achieve pressures of up to 16 Bar using only a single stage air end. It is designed for continuous operation. The rotors are made from a propietary self-healing composite material. They run on wear free floating bearings which have an unlimited life cycle. The distilled water used in the system is constantly replenished from a dedicated dryer which is supplied with the compressor. There is no oil anywhere in the whole system which means that there are no costs involved for oil and oil disposal. It also gives peace of mind that there will be no contamination due to a seal failure. These units are priced lower than the equivalent dry screw compressor and have a significantly longer service life than the equivalent scroll compressor. All AQUA AIR compressors come with a One Year buy back Warranty.

    sullivan palatek aqua air water lubricated oilless oil free rotary screw air compressor inlet valve

    The inlet valve is designed to be totally oil and grease free. A special coating on the valve bushing along with water lubrication guarantees reliable operation. A three-stage heavy-duty inlet filter with remote inlet connection are standard supply. The valve head closes 100%, making it leakage free.


    sullivan palatek aqua air water lubricated oilless oil free rotary screw air compressor water filters

    The water filter, and injection manifold are directly bolted together. The sealing O-ring between both components ensures no leakage. The water filter has separate filter elements for the operation of the system, and the lubrication of the floating bearings during start up. Pre-pressure control for the supply of the floating bearings and a non return valve are integrated into the injection manifold.

    sullivan palatek aqua air water lubricated oilless oil free rotary screw air compressor bulk water separator

    The cyclone separator removes any liquid condensate from the output air and returns it to the operating system. It does this without any flotation valve, or any other mechanical, moving components ensuring wear free operation.



    sullivan palatek aqua air water lubricated oilless oil free rotary screw air compressor air end

    Self healing composite rotors run on wear free water lubricated bearings. During start-up, the bearings are pressurised with water by a pump. After a period of 4 seconds, the hydrostatic mode changes to hydrodynamic operation.
