A maintenance free, noise less blower because of no friction, no vibration & needs no lubrication at all. Consequently, completely wear & tear free.

Based on revolutionary innovation, It is comparatively quieter, lighter and practically maintenance & oil free substitute of the noisy, bulky, oily and monstrous type of conventional air blowers, for the applications where large and forceful suction and pressure capabilities are required in agitation of chemicals.

Since there is absolutely no friction between any two parts of the blower, hence no lubrication is required and consequently the pressurized air or vacuum generated by the machine is 100% oil free.

Since these blowers are compact, maintenance free and need no oiling at all, these are most suited for mounting inside the machines meant for electro plating, dust collecting, printing , paper handling, Vacuum packaging, pneumatic conveying and hence are quite popular with OEM.

Available in Single, Double & Multi bladed turbine, or side channeled impeller versions, suiting various applications dependent upon High Pressure Low displacement or Low Pressure High Displacement requirements.

Applications

Aeration, Bottle Drying, Agitation, Air Bearing, Oil Burners, Dryers, Jacuzzi, Medical Bath Tubs, Hopper Car, Laminating Press, Vacuum Conveying, Vacuum Desolders, Blood Taking Equipment, Bottle / Liquid Filling Stations, Vacuum Packaging, Industrial Vacuum Systems, Dust / Trim Collection, Vacuum Lifting & Forming, Feeding, China Clay Crockery Casting, Air Pollution Monitoring, High Speed Labelling Machines, Paper Counters, Fume / Smoke Extraction Units, Garment Vacuum Tables etc.
