Positive Displacement Blowers | Vehicle mounted blowers

Supplier: Hurll Nu-Way

Carpet cleaning, building insulation and crop dusting have one thing in common - blowers, mounted on trucks.


Have you heard of retrofitting building insulation with the help of a blower? This method allows for insulating both brick veneer and double brick walls. The building cavity walls are filled with blown insulation material fed from a hopper. In this case insulation material, hopper and blower are mounted on a vehicle.

In fogging applications, air supplied by blowers is mixed with a liquid and pressed via the nozzle to create a fine mist. For example, insecticide solution, combined with air, gets atomized and sprayed as small droplets. This process is used for crop dusting, fruit spraying, tree fogging and pest control.

For carpet cleaning, mobile carpet cleaning machines use a hot water extraction method, and a blower provides suction to lift dirt from the carpet.

Other typical uses of vehicle mounted blowers are pneumatic loading / unloading of food products, animal feeds and minerals. Mobile blowers are also used for cleaning purposes, such as drain cleansing, vacuum cleaning, or mobile waste cleaning.

Typical GE Roots models used for these applications are URAI, compact blowers engineered for continuous use with maximum reliability. These blowers have a time tested lubrication system. GE’s exclusive “figure-8” gearbox design improves oil distribution to the timing gears and lengthens bearing life.

Oversized anti-friction bearings are used, with a heavy duty cylindrical roller bearing at the drive shaft to withstand V-belt pull. Viton™ lip seals maintain proper lubricant at the bearings.

Characteristics of the URAI model range of compact mobile blowers :

  • Very cost effective design
