The structure principle of OPPAIR screw air compressor

The OPPAIR screw compressor is a positive displacement gas compression machine with a working volume for rotary motion. The compression of the gas is realized by the change of the volume, and the change of the volume is achieved by the rotary motion of the pair of rotors... Read More

Compression principle of OPPAIR screw air compressor

1. Inhalation process: Motor drive/internal combustion engine rotor, when the tooth groove space of the main and slave rotors is turned to the opening of the inlet end wall, the space is large, and the outside air is filled with it. When the end face of the inlet side of... Read More

Why can OPPAIR inverter air compressor achieve energy saving and high efficiency?

What is an inverter air compressor? The variable frequency air compressor, like the fan motor and water pump, saves electricity. According to the load change, the input voltage and frequency can be controlled, which can keep the parameters such as pressure, flow rate, te... Read More
