SR Vacuum

SR Bi-Lobe Exhauster

The SR bi-lobe bare shaft machines incorporate the latest vacuum design. 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.
