Rotary-Type Air Compressor

Rotary air compressors compress air through the meshing rotation of two helical rotors, generating a continuous airflow. They are used to provide power sources for equipment and pneumatic control, ensuring stable pressure in applications such as painting, mixing, and material conveying.
Selection
Select the exhaust capacity based on gas consumption, matching a working pressure of 0.7–0.8 MPa. Consider environmental ventilation and power supply conditions when choosing between oil-lubricated or oil-free models. Regularly inspect filters and drain condensate, and keep the cooling fins clean.
