Product Description

A positive-pressure ventilation fan is a fan that forces air into evacuation stairwells. It pushes outdoor air pressure into the interior spaces. When a fire breaks out in a building, large amounts of toxic gases such as smoke and carbon monoxide are generated, obstructing visibility. By using a positive-pressure ventilation fan to supply fresh air to the evacuation stairways, we can prevent smoke from entering the stairwells, thereby creating favorable conditions for people to escape safely. Typically, positive-pressure ventilation fans are installed on the roof of a building and are linked to positive-pressure dampers on each floor. In the early stages of a fire, the dampers are opened and the positive-pressure ventilation fan is activated, maintaining a positive pressure within the stairwells and elevator lobbies.
