Product Description

Stainless Steel Roof Vent Turbine Smoke Exhaust Ventilator Roof Top Ventilation Fan for Effective Outdoor Ventilation

No-power Roof Turbine Ventilator is to make use of the air free convection that natural wind power and the interior outside temperature difference bring about, the effect driving a turbine to rotate making use of centrifugal force and negative pressure thereby discharge the interior stale hot-air.It makes the fresh air flow in, thus the purpose of cleaning air can be reached

UNCTIONS &FEATURE:
1.It can absorb the hot air, moisture, dust, foul smell, smoke from residence and from kitchen chimneys of workshops
automatically, also it can decrease indoor noise, increase light.
2.It runs automatically all the time and no stop according to natural weather; It doesn't need any power, saving energy and cost.
3.It is installed on the top of buildings or on the wall with good appearance.
4.Simple and convenient installation, No Operational and Maintenance Cost.
5.No roof leaking, 100% waterproof result with raining or snowing weather.
6.Enhances the architectural and aesthetic appearance of buildings.
7.It suits all roof types with slopes from zero to 22.5degree.
8.Precision steel bearings imported from abroad.
9.Improves efficiency of air conditioning. Where ducted air conditioning is installed at home. It will lower roof space temperatures, thereby reducing the level of heat exchange occurring between air in the attic and the cool air carried within the ducting system. This in turn causes less strain on the air-conditioner unit

How to calculate and determine the number of ventilators 1. Determine the indoor volume of the building vol (length x width x height) 2. According to the type of building, the air rate required per hour is determined by table 1 a/c 3. Determine standard wind speeds based on local meteorological records (6, 8, 10, 12, and 16 km/h) 4. Calculation formula for the number of ventilators: number of ventilators =volxma/c/ the ventilation capacity (m3/h) is determined by table 2
