Motorized Power Ventilators

Motorized Power Ventilators

These are ventilators which are electrically powered by motors. Typical Application areas are where continuous exhaust of very high volume of air is required at specific interval for specific durations. E.g. Casting / Melting Foundry, Chemical Plants, Steam Plants etc. The efficiency of Conventional Ventilators is dependent on wind velocity. The wind velocity may not be adequate at times when maximum exhaust is required. The Motorized Ventilators provide an option for exhaust of polluted air during such specific events. When used along with conventional ventilators they can provide very efficient exhaust with minimal power consumption. The efficiency of Conventional Motor driven exhaust is compromised when installed on walls mostly nearby windows and doors. Most of the air being exhausted is sucked from windows or doors nearby instead of the apex of the premises where maximum hot air accumulates. Installation of Motorized Ventilators on the apex is the best location for providing maximum exhaust of hot air / smoke / gases.

Balancing : fan will be dynamically balanced for vibration free running.

Technical comments:
The initial/project cost of the fan will be low.
The tensile weight of the fan at roof elevation will be less.
Motor H.P power consumption will be less, tends to less
Electrical power consumption and minimize the total running cost.
Fan blade will be of ms epoxy coated light weight moulded gives the low dynamic torque on the roof.
Ease in installation and maintenance if any in future.
Top canopy will be of light weight made of FRP moulded.
Special class construction with very easy to be mounted at roof level.

Technical advise / solution:
Fan diameter will be of 32” made of completely FRP of 5mm thk.
Motor will be of 1.5 hp/960 rpm having its max. Current capacity up to 3.2 amps.
FRP sheet with one piece fan casing(round section) to be self molded with sheet to avoid any leakages from roof.
FRP sheet of size- 1057mm x 2000mm as per your existing roof profile having 3.5 mm thk.
