Fixed Speed 15 Hp Rotary Screw Air Compressor / Oil Lubricated Air Compressor


High efficient centrifugal fan-cooling control system of double frequency (optional package)


  • centrifugal fan-cooling permanent magnet motors adopt variable frequency control technology. They can save about 50% of the energy. Rotation speed of the cooling fan can be adjusted according to gas emission temperature, so as to reduce power consumption. Stable temperature of the overall system can improve durability of parts. In addition, variable frequency cooling fan can lower the noise.
  • Centrifugal cooling fans are characterized by high efficiency, low noise, balanced pressure curve and other outstanding performances.

Energy Saving


  • Traditional compressors (standard machine) usually use ON / OFF or proportional regulation system, which adjusts the opening amount of the air inlet of compressor. The adjustment method can also meet the actual requirements of the actual gas consumption, but the revolving speed of the compressor maintains at the rated speed in the entire adjustment process, the frictional work and cooling fluid agitation work will not be reduced, so although the gas consumption is lowered, the actual power consumption is not limited substantially. The variable frequency regulation can make the actual power consumption of the variable frequency compressor decline in the same proportion, and the energy is effectively used into the air compression.
  • In the market environment with fierce competition, it is an important matter as to whether the cost can be reduced. With the use of PM frequency conversion technology, you can save energy, thereby decreasing electricity expenditure sharply. It adjusts the compressor production capacity automatically according
