Detailed Specifications
General Features
Designed according to the principles of aerodynamics, positive inducing fans induce and disturb surrounding Air through the high velocity discharge produced and then guide the air in specified directions.
The central Discharge velocity gradually comes down with the increasing distance away from the outlet nozzle, but the Discharge area expands so that more air can be induced. By diluting indoor harmful gases and circulating air at the same time, positive inducing fans can gather these gases and bring them along the predefined flow Passage quickly to the exhaust fan, thus making the air well ventilated in the underground car parks also it has the following features:
Greater efficiency and long discharge distance.
Silencers fitted at both inlet and outlet for extremely low sound level.
Aesthetically pleasing, small-size, light-weight and space-saving.
Easy installation with mounting brackets supplied and mounting angles adjustable.
Air inlet mounted with safety guard to ensure safe working conditions.
