Have you ever heard of retrofitting build­ing in­su­la­tion with the help of a blower? Well, a blower can be used to fill a build­ing’s cav­ity walls with in­su­la­tion fed from a hop­per mounted on a ve­hi­cle.

When it comes to clean­ing car­pets a blower unit pro­vides suc­tion to lift dirt from the car­pets.

In fog­ging ap­pli­ca­tions, air sup­plied by a blower can be mixed with a chem­i­cal and pressed via the noz­zle to cre­ate a fine mist – it can be used for spray­ing in­sec­ti­cide. Com­bined with air, the liq­uid is at­om­ized and sprayed as small droplets, a sys­tem that can be used for crop dust­ing, fruit spray­ing, tree fog­ging, or for pest con­trol.

A typ­i­cal GE Roots model used for these ap­pli­ca­tions is the URAI, a range of com­pact blow­ers en­gi­neered for con­tin­u­ous use with max­i­mum re­li­a­bil­ity. These blow­ers have a time tested lu­bri­ca­tion sys­tem.

Over­sized anti-fric­tion bear­ings are used, with a heavy-duty cylin­dri­cal roller bear­ing at the drive shaft to with­stand V-belt pull.
