The Roof Vent 600mm (Cyclone) is a wind-powered turbine ventilator used to extract accumulated heat, fumes, and odors from buildings. It works by creating a low-pressure zone on the sides of the spinning blades, which causes moving air to flow across the blades of the vents. This creates a high-pressure zone inside the building, which forces heated air to rise and flow through the openings of the vents into the low-pressure zone created by the spinning blades, thus extracting undesirable air.
