Longer bearing life
Less shock transmitted through the impellers means approximately 20% longer bearing life. Other components such as timing gears, drive couplings, v-belts and motor bearings suffer less stress, too.
Lower energy consumption
The patented ROOTS WHISPAIR’s jet design precisely meters backflow and channels air pressure in the direction of impeller rotation. The result is an extra “push” that reduces the power required to drive the impellers.
Pressure pulses are also the major source of blower and gas blower noise. The pressure equalising effect of the Whispair™ design reduces noise by approximately 5 dBA, while reducing wear on your piping valves and sensitive instrumentation.
Every Roots blower is mechanically tested to design extremes of speed, pressure and temperature. Roots validate the flow capacity as well as major critical factors such as vibration, oil circulation and operating clearances. This ensures your blower is manufactured to the highest standards with performance proven to meet your process needs. Special testing requirements are welcome.
Cylinder and headplates
All units are configurable to horizontal or vertical flows. Cylinders and head-plates are precision machined grey iron, with cast ribs for improved strength and heat transfer. All RAS-J and RGS-J blowers incorporate a wrap-around plenum design and feature ROOTS’ exclusive WHISPAIR™ jet. Castings may be subjected to strenuous pressure and leak testing to ensure integrity in the most demanding applications.
