Positive-pressure air supply outlet
Our company manufactures positive-pressure supply air outlets—also known as multi‑blade pressurization supply air outlets or fire‑compartment supply air outlets—which are specialized devices installed in building smoke control and exhaust systems, typically in stairwell anterooms, shared anterooms, and fire‑elevator lobbies. Normally closed, these outlets are opened upon activation of the fire‑alarm linkage system during a fire to deliver fresh air into the stairwell or anteroom, creating positive pressure that prevents smoke from entering evacuation routes and ensures the safe evacuation of occupants.
