Ridge Ventilators

We introduce Power vent, zero electrical power consumption ventilator (exhaust fan). The turbine shaped Power vent fan is a vertical mounted unit on the top of the roof of covered area from where the unwanted hot air is to be evacuated continuosly. Which circulates fresh air in the bottom layer of shed without any electricity. This can be fixed in any kind of roofing such as metal roofing, asbestos, frp, and other roofing categories.

The normal environment of any workspace, factories, godowns, process house sheds, kitchens, in hotels, boiler houses, workshops etc., demands good ventilation for a healthy atmosphere Are the steel roofing is better suited to the Indian climatic conditions. This can be available with frp base, aluminium base and steel base.

Works efficiently within the normal available parameters of temperature, pressure and height of roof in most of the locations needing ventilation of polluted air.

Principles of operation:

As the air is heated or is warm it becomes lighter and fends to move upward. If it is made to escape from a single or multiple narrow openings from top, the hot air will escape at a faster pace causing a natural draft to exist at the opening. This draft is made use by the Power vent to self driv the turbine causing the exhaust gases to be expelled at a faster rate. The rate of expulsion of gases is directly proportional to

1. Temperature if exhaust gases

2. Pressure within the room and flow of atmospheric air outside

3. Height of the roof of the room

Advantages of Power vent exhaust:

1. Power vent is cost effective as it consumes no power

2. It is light in weight, noiseless and environment friendly

3. In the long run Power vent definitely adds to your profits

4. Its pay back period is extremely low

5. It is fully protected against corrosion

6. Once fitted, it has trouble free long working life with practically no maintenance


Technical parameters:

1. Speciality of Power vent is inbuilt with three internal wings to cut the hot air and push it out effectively in a large volume.

2. We provide 10 years performance warranty

3. For performing long life we use US 332 shield bearing
