Design & construction
The choice of vane material, size, quantity and layout of installation depends on various factors such as wind velocity, environmental conditions, size and location of the building, profile of the roof, activity in the building & number of air changes required. The ventilators are available in both Aluminum and Stainless Steel versions. Our unique Aluminum vane design loaded on special grade steel pins with bearings; prevent wear and tear while in rotation. The customer has a choice of either Steel or Fiberglass for the base frame.
Roof ventilators ranging from 14" to 36" sizes are available which are recommended after considering the above factors. The ventilators are also designed in a way that prevents leakage and down draft into the building allowing air entry from the side openings.
