No power involved for its operation as its movement is controled by natura wind movement / hot air draft (Thermos Syphoning).
The vane's are profiled and rolled to provide strong blade with good aerodynamic performances.
Air Power Ventilator's vane are manufactured from high grade aluminium including the rivets and therefore highly resistant to atmoshperic corrosion.
Air Power Ventilators are light in weight and hence operational at very lightly wind speeds.
Since no power involved for its operations, no recurring charges in terms of electricity.
The vane design and the centrifugal action prevent rain water from entering the ventilator.
Designed to be fitted easily on asbestos, galvanized, iron and aluminium roofs.Assured ventilation for 24 hours / 65 days.
|How To Calculate A Requirement of air Ventilator:|
|No. of Ventilator Required = Ventilation Rate Q |
|Required Ventilation rate (cfm)= Volume (ft) x Air Change Rate |
|Volume of Space to be ventilated (ft) = 1xwxh|
|Select Air Change Rate from. Table A.|
|Select Exhaust Capacity from Table B as per required Temp.|
|Diff. C and wind- Velocity (MPH).|
