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
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).
