In the event of a fire, evacuees must evacuate to a smoke control area (Pressurized Smoke Control Zone) that has pressurized air to prevent harmful smoke from entering. During this time, if excessive air is supplied to the Pressurized Smoke Control Zone, the pressure inside this zone becomes higher than the external pressure, making it difficult to open the door.

The Barometric Damper is a breakthrough pressure regulator that can solve this problem. This is a device that maintains the pressure in the Pressurized Smoke Control Zone at constant level by discharging the air inside the Pressurized Smoke Control Zone to the outside when air is supplied excessively to the extent that the pressure inside the Pressurized Smoke Control Zone exceeds the appropriate level. (Korea Fire Insitute (KFI) certified product)

Key features

Easy installation

A pressure control device that is installed between the Pressurized Smoke Control Zone and the outside to discharge excess air. It is a mechanical device that does not require electrical equipment (piping/wiring) installation, so it can be easily installed.

Accurate pressure control

the best pressure regulating device to implement for maintaining the pressure in the Pressurized Smoke Control Zone at an appropriate level, as it even works with micro pressure of 1Pa.

Easy maintenance

Since it consists of a mechanical device with a simple structure, which does not require a separate power source, maintenance and management are easy.

The product can be manufactured in two ways (forward/reverse) according to the discharge direction.
