Positive pressure air supply outlets are designed to increase air pressure and supply air during a fire, ensuring a continuous supply of air to the antechamber through the outlets, maintaining positive pressure in the space.

Pressure is applied to ensure that smoke does not spread in this area, providing space for escape. When the temperature exceeds 280°C, there is no possibility of escape.

Internal circuit breakers will trip, automatically closing the air outlets to prevent fire spread. Typically installed on the walls of stairwell vestibules and smoke shafts, they can also be

Mounted on the side of smoke control system piping or at the end of the duct.
