Most of the manufacturers here follow American and British Practice for Blower construction. They select from two types i.e. Volume Blower and Industrial Exhauster. The selection is therefore limited at lower efficiency. Many times economy in first cost is achieved at cost of efficiency.

Vacunair follows German practice to offer seven types of aerodynamic designs. Each type has twenty sizes between 200 to 2000mm diameter.

This makes possible to select from wide range resulting in high efficiency. Each type is efficienct for a given capacity. Pressure and speed helps to select direct drive of synchronized speed without sacrificing efficiency.


Similarly for all Axial Fans, they have selection from seven hub ratio. This makes wide choice of sizes to achieve efficiency. Aerofoil blades with variable pitch adds to flexibility in selection and use.


They also manufacture Pneumatic Conveying System including Catalyst Loading & Unloading System and have supplied and commissioned at IOCL-Haldia, IOCL-Baroda, BPCL-Mumbai through L&T Ltd., Mumbai and Mathura Refinery through Daelim Engineering Co.
