Discover some of the cool science behind our roof turbine ventilator
Working Principle of Roof Turbine Ventilator
Wind Driven Effect: The ambient wind from outside the building created energy to turns the ventilator when passes by the vanes hence forming a centrifugal suction to the air inside the building.
Stack Effect: Difference in temperature between the outdoor air and indoor air created pressure differences resulting positive buoyancy force. This force will turn the ventilator when passes the vanes.
unimax ventilators are build to last long. Only the finest quality bearings are used because we know that bearings are heart of the ventilator. Therefore we evaluate following criteria as recommended by bearing's manufacturer prior selection of use:
