Air flows are available from 20m3/h, all the way up to 10,000m3/h at pressures up to 1 bar. The HB roots type bare-shaft blower incorporates the latest blower designs and have the use of oil at both ends. The casing is constructed of cast iron and ribbed to ensure adequate heat dispersal and increased rigidity. All rotors are dynamically balanced which reduces vibration, wear and tear on the bearings and eliminates stress fractures on the silencers.
