SVS Windy Ventilators are always spinning... always ventilating. Non-stop ventilation is possible due to the integrated bearing housing, which ensures ventilator rotation at even wind speeds of less than 1 KM per hour.

OK Tested

Stable in 125 KpH wind test

Leak proof in heavy rain test


Extremely low starting speed ensures non-stop rotation and continuous ventilation

Strong construction. Higher vane thickness prevents shearing in high winds

Vertical installation using variable angle elbow

Bearing protected against dust, smoke, fumes

Highlights of shorter length FRP base design and unique installation procedure

Installation procedure of ventilator ensures that it does not get uprooter in high winds

Special FRP base design and installation procedure prevents accidents of people working on the roof

Leak proof installation

Completed installations

The mechanics of air movement are very simple. The hot air inside the shed tends to rise up. When the ventilators rotate, they suck the warm air out through the vents, allowing a supply of fresh air at ambient temperature through the doors and windows.
