Salient features
- Air Power Ventilator's vane are manufactured from high grade aluminium including the rivets and therefore highly resistant to atmoshperic corrosion.
- 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 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
Exhaust Capacity
|
Required Ventilation rate (cfm)= Volume (ft) x Air Change Rate
60 |
| 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). |
