Are you still wasting time looking for Air Compressors suppliers?
Do you still worry about product quality assurance?
Are you late in deciding to buy because of insufficient budget?
If you have these worries, stay and see.

NEW HW-31/25 Screw Air Compressor

Main feature of the HW-31/25 Screw Air Compressor
It fully realizes Convex-Convex engagement to assist in the formation of hydrodynamic lubrication film, to reduce horizontal leakage passing the contact zone, and to improve efficiency of the compressor; improve rotor processing and testing property.
It adopts the design thought of "large rotor, large bearing and low speed method, thus its revolving speed is 30-50% lower than that of other brands to reduce noise, vibration, and exhaust temperature, improve rotor rigidity, increase service life, and reduce sensibility to sundries and oil carbide.
Its power range is 4~355KW, where 18.5~250KW applies to the compressor without direct-coupled gearbox, 200KW and 250KW apply to the compressor with Level 4 direct-coupled motor and the speed is as low as 1480 rmp.
It fully conforms to and exceeds requirements in GB19153-2003 Limited Values of Energy Efficiency and Evaluating Values of Energy Conservation of Displacement Air Compressors.

Enhanced Lubrication Efficiency:
Experience superior performance with our advanced "Convex-Convex" engagement design.
This innovative feature facilitates the formation of a hydrodynamic lubrication film, reducing horizontal leakage in the contact zone.
This not only enhances the efficiency of the compressor but also improves rotor processing and testing properties.

Quiet, Low-Vibration Operation:
Embrace the "large rotor, large bearing, and low-speed" design philosophy, setting our compressors apart from the rest.
With a 30-50% lower revolving speed compared to other brands, enjoy reduced noise, vibration, and exhaust temperature.
This design also enhances rotor rigidity, prolongs service life, and minimizes sensitivity to debris and oil carbide.

Versatile Power Range:
Our compressors cover a power range from 4 to 355KW. For compressor applications without a direct-coupled gearbox, choose from the 18.5 to 250KW range.
For those with Level 4 direct-coupled motors, opt for the 200KW and 250KW options, featuring an impressively low speed of 1480 rpm.

Exceeds Energy Efficiency Standards:
Rest easy knowing that our compressors fully conform to and surpass the requirements outlined in GB19153-2003.
We not only meet but exceed the Limited Values of Energy Efficiency and Evaluating Values of Energy Conservation for Displacement Air Compressors.


All machines have passed the EU CE, France TUV, ISO quality certification.
Don not worry about shipping, well choose the nearest shipping place to ship at the shortest time.
