A World Class Manufacturer of Air Compressors

The screw air compressor primarily consists of a casing and a pair of screws (or rotors). The working principle of this compressor involves an electric motor driving the screws to rotate through a pair of speed-increasing gears. When the tooth grooves of the two rotors separate, the space between the teeth increases, allowing air to be drawn in through the intake chamber. The teeth then fill with air. When the rotors mesh again, the space between the teeth decreases, compressing the air, which is then discharged through the exhaust chamber.

Compact and Lightweight: The compressor boasts a compact design and lightweight construction, making it easy to install and maintain.

Convenient Maintenance: Its modular design facilitates quick and easy access to components for maintenance and repair.

Advanced Air Volume Control Technology: The compressor utilizes advanced air volume control technology, enabling it to output 20%-30% more gas flow under the same discharge pressure compared to conventional air compressors.

Reduced Power Consumption: For the same gas flow, it consumes only 13-12 of the power required by traditional compressors, leading to significant energy savings and reduced operating costs.

Inverter-Driven: The compressor is equipped with an inverter that adjusts the motor speed in real-time based on actual air consumption, enabling precise control of the air output.

Automatic Standby Mode: When air consumption is low, the compressor can automatically enter standby mode, further reducing energy waste.

Enhanced Stability and Reliability
Stable Pressure: By adjusting the compressor's running speed according to air consumption, it achieves stable pressure output, eliminating pressure fluctuations and reducing mechanical wear.
Soft Start: The soft start feature ensures smooth startup, eliminating peak currents associated with traditional direct or Y-Δ starts, thereby extending the life of motors and electromagnetic contactors.

Adjustable Discharge Volume: The compressor offers a wide range of adjustable discharge volumes, allowing it to adapt to different usage requirements, typically ranging from 0.3 to 1.5 MPa.

Automatic Pressure Maintenance: Equipped with an automatic pressure maintenance system, the compressor ensures continuous and stable air supply, minimizing disruptions to your operations.

Long Service Life
Permanent Magnet Synchronous Motor: The rotor of the permanent magnet synchronous motor is made of neodymium-iron-boron material, which forms a strong magnetic field. This enhances the motor's durability, with a service life that can reach up to 100,000 hours, significantly longer than that of conventional asynchronous motors.
