Introduction

The two-stage screw compressor adopts a two-stage compression structure. It consumes less
power and delivers more stable air pressure. Ideal for large air flow applications, it operates reliably
with a long service life.

 

High-Efficiency Profile

T-type rotor profile delivers world-class efficiency — 5%–15% higher than conventional designs.

 

Energy Saving

Premium configurations and system optimization deliver 5%–8% higher efficiency than competitors,
with tangible energy savings from the DWS series’ advanced technologies.

Stable & Low Maintenanc

Rotary screw technology eliminates air pulsation for smooth, reliable operation in all
conditions, with minimal maintenance and low operating costs.

  • Flexible hose
    The pre-filter before inlet valve traps dust and impurities,
    preventing contaminants from wearing rotors inside the screw compression
    air end.
  • Vacuum Inlet Valve
    It stably controls air intake with precise sealing,
    delivering fast response, zero leakage and minimum operational pressure
    loss.
  • Airend
    Rotating screws compress air while oil seals and lubricates;
    high-precision rotors ensure high output, low energy use and long
    service life.
  • Vacuum Inlet Dust Filter
    This front filter intercepts airborne dust and sundries,
    stopping pollutants from accessing internal parts and causing abrasion
    to rotating rotors.
  • Vacuum Buffer Tank
    It cools pressurized air down to normal temperature. Large
    heat area achieves efficient cooling, less condensed water and better
    compressed air quality.
  • Motor
    It supplies power to drive the screw air end. High
    efficiency design ensures steady running, low loss, few faults and long
    service lifespan.

  • Thermostatic Valve
    Regulates the lubricating oil cooling circuit and controls
    oil temperature. Features fast thermostatic response and precise oil
    temperature regulation, preventing high-temperature damage to components
    and ensuring stable oil circulation.
  • Vacuum Buffer Tank
    Allows gravity settling of the oil-air mixture to achieve
    preliminary oil-air separation. Made of thickened explosion-proof
    material with strong pressure resistance. The internal flow-guiding
    structure provides excellent primary separation efficiency and reduces
    residual oil mist.
