Industrial Blower

Oil-free screw blowers are available for flow rates from 239 to 8605m3/hr, and operating pressure ranging between 0.3bar and 1.2bar. This screw blower can reduce energy costs up to 35-40% compared to roots blower. It featured by quiet operation, driven by a variable speed, permanent magnet synchronous motor, and controlled by microprocessor controller and remote control system.

Free air delivery
0.81-22m³/min
Power
7.5-132kW
Discharge pressure
0.8-1.25MPa
