The Curvent Fire King R ventilator is a dual-purpose ridge mounted smoke and heat exhaust ventilator. The ventilator combines comfort with life safety. The ventilator offers permanent natural day to day ventilation of hot stale air within the building which is replaced with cool fresh air through fixed louvres and other openings at low level, vastly improving indoor air quality. In the event of fire, the ventilator doors automatically open on gravity to allow hot gasses to exhaust. This will aid in the buildings’ structural integrity against building collapse. The smokeless layer of fresh air created at lower level creates safe evacuation passage for people and assist in firefighting disciplines.   

The flowing curved lines of the ventilator enhance the coefficient capabilities and provides appealing aesthetics. The ventilator is manufactured using Computerised Numeric Control machines, eliminating manufacturing flaws. The ventilator is transported in knock down format to protect it against damage. The ventilator features a unique user friendly “Clip-On” installation system allowing fast and easy installation procedures that will reduce installation time and cost.
