Features

Energy saving
Thanks to the adiabatic compression principle, the total efficiency of oil-free screw blower exceeds 75%, saving more than 20%-35% energy than the Roots blower. The blower is featured with higher discharge pressure and lower pressure pulse.

Low noise
The aerodynamic noise of the screw rotor is very small, and the smooth output eliminates the sudden release of internal air, and the wavy inlet and air outlet minimize airflow fluctuations, so the noise is less than that of traditional blowers.

Intelligent
Intelligent PLC control, remote control and various communication methods are convenient for operation and management

Low cost
The optimized structural design enables the durability of the product with less consumption. Also no special infrastructure is required due to the smooth running and small load of the unit.

Description of blower parts

Shaft screw blower main body	high efficiency profile rotor design ● adopt synchronous gear and drive gear of national standard precision grade 5 ● Innovative bearing arrangement of screw, fixed radial bearing and thrust bearing adopted to increase the service life ● oil and gas separation between compression chamber and lubricating chamber realized by Labyrinth seal + carbon ring seal, ensuring the discharge of pure air.
Permanent magnet motor	Magnetic properties, no external energy is required to maintain its magnetic field ● High efficiency and energy saving, the average efficiency of 75%- 80% can be achieved in the speed range of 1500-6000r/min. ● High accuracy in voltage regulation can prolong the battery’s service life. ● No brushes, no collector rings, and no sparks generated during operation, so there is no wireless interference, which greatly improves the operation performance.
Oil lubrication system	More reliable forced circulation lubrication cooling system separately designed ● advanced oil circuit system composed of oil pump, oil cooling and oil filter ● low oil temperature enables longer service life of bearings and gears
Operation control system	Integrated station monitoring instrument, signal control module, inverter, touch screen, etc., no additional installation required ● the selection of driving components is optimized, and parameter settings can accurately achieve higher efficiency ● Complete automatic control and protection functions, and realize online control and remote control at the same time ● A variety of operating modes, enabling users to adjust the operation to be more power-saving mode according to the changes in working conditions
