Oil-free screw blower
Working principle of screw blower
- suction start
- suction ends, compression begins
- During compression
- Compression ends, exhaust begins
Oil-free screw blower has the following performance advantages
1) low energy consumption
The oil-free screw blower is based on the principle of adiabatic compression, with a total efficiency of over 75%. It can save 20%-35% more energy efficient than Roots blowers. Higher exhausting pressure, lower pressure pulsation.
2) Low noises
The aerodynamic noise of the screw rotor is very small, the smooth output eliminates the sudden release of internal air
And the wave-shaped inlet and air discharge port minimize the fluctuation of air flow, and the screw blower noise is lower than that of traditional Roots blowers
3) Intelligent
Intelligent PLC control, remote control of multiple communication methods, easy for operation and management.
4) low cost
The optimized structural design allows us to consume less and ensure the durability of the product. At the same time, the product runs smoothly with a small load and no special infrastructure is required. Maximize customer benefits

G series oil-free screw blower
The internal air path of the G series oil-free screw blower has been optimized to reduce pressure drop and air turbulence.
Saving factor:
1. Internal compression
2. Integrated gearbox
3. Smooth silencer
4. inlet air filter
When the pressure is 0.8bar, the screw blower consumes only 42kW on average and can provide air flow rate of 1600m3/h
Continuous operation
In harsh and dusty application condition, a reliable supply of compressed air is crucial to ensure continuous production. The design, producing and testing of our oil-free screw blowers are in compliance with GB/T 15487. The fully enclosed IP54 motor can ensure continuous operation in dusty and humid environments with excellent reliability.
Protect producing process
In almost all applications, oil pollution in compressed air can cause serious producing problem and then increase costs. G series oil-free screw blowers set a new standard in air purity and meet today's increasingly high air quality requirements.
Easy installation
G series oil-free screw blowers are ready for use once delivered. The complete supply does not require any additional purchases by the customer, it easy to install, saving time and costs.
The G series oil-free screw blower can be directly installed into the existing pipeline, and can be started and operated directly.
