Screw Vacuum End
Rotating screws compress air while oil seals and lubricates; high-precision rotors ensure high output, low energy use and 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 hoseThe pre-filter before inlet valve traps dust and impurities, preventing contaminants from wearing rotors inside the screw compression air end.
-
Vacuum Inlet ValveIt stably controls air intake with precise sealing, delivering fast response, zero leakage and minimum operational pressure loss.

-
Vacuum Inlet Dust FilterThis front filter intercepts airborne dust and sundries, stopping pollutants from accessing internal parts and causing abrasion to rotating rotors.
-
Vacuum Buffer TankIt cools pressurized air down to normal temperature. Large heat area achieves efficient cooling, less condensed water and better compressed air quality.
-
MotorIt supplies power to drive the screw air end. High efficiency design ensures steady running, low loss, few faults and long service lifespan.
-
Thermostatic ValveRegulates 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 TankAllows 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.
