Screw Blower BLG280RA
Working Principle
1. Suction starts
2. Suction ends and compression begins
3. During compression
4. Compression ends and air discharge begins
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.
Parameters
