Introduction
VFS series are single inlet centrifugal fan with forward curved blades. These are suitable for supply or exhaust application in industrial and commercial buildings.
These series are available in eighteen (18) standard nominal diameters from 200 up to 1400mm

Construction
impeller, The impeller has forward curved blades manufactured from high quality galvanized sheet steel. All impeller are statically and dynamically balanced to ISO 1940 standards.
casing, for all sizes exceot 1400, the casing is manufactured from high quality galvanized sheet steel with the casing fixed to the side plates in lock form system. For size 1400, the casing is manufactured from mild steel finished with polyester paint coating.
bearings, all bearings are either deep groove ball bearings type sealed at both sides. The bearings are lubricated for life and maintenance free. if lubrication is necessary, it is recommended to use a lithium base grease suitable for all temperatures within the operational limits.
Shaft, the shaft are C40 carbon steel using automatic process for positioning and keyways cutting. All tolerance 100% check to ensure precision fit

Fan rotation and discharge
The direction of rotation is determined from the drive side of the fan

Motor Position
Location of the motor si determined by facing the drive side of fan and designating the position by letter W,X,Y or ZDownload PDF
