Product description

1. The screw air compressor has the advantages of high stability, high efficiency, low vibration and low noise.

2. The yin and yang rotors and the coordination between the rotor and the casing are set, so that the backflow leakage of the gas is less, and there is no residual clearance volume, so the efficiency is high.

3. The injected lubricating oil has the functions of sealing, cooling, noise reduction and lubrication

4. Compared with piston machine, it has less wearing parts and lower failure rate.

5. The screw compression working curve is smooth, with less vibration and low noise compared with the piston machine.

6. The cooling method is generally divided into: water cooling and air cooling.

7. Heat dissipation system: plate-fin structure and high-quality materials are used to ensure that the cooler can withstand pressure, have high heat dissipation efficiency and good corrosion resistance.

8. Air filter: heavy-duty, multi-stage air inlet filter, dust removal accuracy 1um (98% is filtered out), large working surface, relatively long service life.

9. Oil/gas separator: The new generation of separator adopts a new filter material, with higher efficiency, and the air oil content is less than 2ppm.

10. Intelligent controller: All operations and related data of the air compressor are displayed on the control panel, which can be controlled between your fingers, easy, convenient and accurate.

Air Compressor Equipment - Screw air compressors drive the compression components at the optimum speed for the application through an efficient drive system. Completely maintenance-free during normal operation.
