High efficiency 
Crownwell water lubricated oil free air compressor adopts pure water with functions of sealing,
cooling and lubricating, free air delivery per unit of horsepower improves 15% than other dry type.

Long repair cycle
Ideal isothermal compression, low-speed design and structural components of the special good design,
airend five-year maintenance-free in normal conditions.

Very low operating costs
Cheaper because of the use of pure water lubrication, without oil, oil separator, oil filters;
the annual maintenance cost of only a few hundred dollars.

Structure of non-lubricants
The complete system doesn’t have any oil involved, water is used as lubricant. Pure water
can lubricate and cool the compressor as well as wash away dust in the air, the compressed air is clean as after rain.

Ideal isothermal compression
Because the cooling performance of water is much better than the oil. The operating 
temperature is only 40 °C, near suction temperature, which achieves a high efficiency and ideal isothermal compression. 

The real environmental protection compressor
Because no oil participates, no any oil pollution happens, all mechanical parts adopt 
rust-proof material such as stainless steel, copper alloys, ceramics, carbon fiber,etc;high-precision water filter ensures the lubrication of water to maintain clean.
