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:
| 1. No. of Ventilator Required = Ventilation Rate Q | ||
| Exhaust Capacity | ||
| 2. Required Ventilation rate ( cfm)= Volume (ft) * Air Change Rate | ||
| 60 | ||
| 3. Volume of Space to be ventilated (ft) = 1*w*h | ||
| 4. Select Air Change Rate from. Table A. | ||
| 5. Select Exhaust Capacity from Table B as per required Temp. | ||
| Diff. C and wind- Velocity (MPH). | ||
