HB Roots Type Blower & Vacuum

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.

Overview

Dynamically Balanced
The HB tri-lobe blower reduces pulsations resulting in less noise and longer bearing life.

Tri-Lobe Rotors
Reduces pulsations resulting in less noise and longer bearing life

Ribbed casing design
Increased surface area ensures efficient heat dispersal across the blower and increases rigidity of the casing.

Dynamically balanced rotors
Reducers vibration minimises overall noise level and increases bearing life.

Labyrinth type seals
Wear-resistant labyrinth seals between the air chamber and lubrication system prevent contamination of the air flow.

Proven Performance
Successfully operating in hundreds of applications worldwide
