2.Triple shaft seal is applied in key parts to eliminate leakage problems. Wear resistant bushing and O-ring are precisely ground for high maintainability. Each product features superior performance and efficiency, providing large exhaust capacity with small motor horsepower. Oil cooler is designed according to the actual working conditions in China, with a large cooler and fan, so that it is suitable for working in harsh environment.

3.The air flow control system can automatically and continuously adjust the air inlet volume and rotary speed of the engine, so that the air supply and consumption are fully matched. This achieves better performance while reducing the oil consumption.

4.KAISHAN portable screw air compressor purchases engines from Commins, Yuchai and other famous brands. These engines have powerful movements, reliable operation, fuel economy and low noise, and the exhaust can reach very high environmental protection standard.

5.The equipped multi-stage air filter system effectively reduces the influence of harsh dusty environment on the engine. The precision filter layer of the main air filter filters out residual dust to protect the machine from wearing out. The safety filter element allows the air filter to be maintained without downtime to ensure safe operation.
