Shangair patent cylindrical direct-flow valve is used by our compressors. The valve is made from the stainless steel belt imported from Sweden and it is free from fracture during the working life.

The piston of our air compressor aplies the integral cast chromium plating ring, the working life is extended by 3 to 4 times.

Shangair’s unique compressor dymanic balancing technology. The vibration is only as a quarter of the world standard.

The whole air compessor adopts rolling bearing without bearing shell (Comprising connecting rod).

To ensure safety and reliability of air compressor, redundancy design principle is adopted and multiple protection measures are taken: such as overload protection; overheat protection; phase-failure protection; undervoltage protection; drainage while stop running; startup under the condition pressure is zero.

High reliability, long maintenance cycle, very low oil consumption (oil-saving), low energy (power saving), these dramatically reduce the general operating cost of our air compressors.
