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.
