Fire Damper

Product Overview

Fire Damper has a temperature fuse (72/103/143/280℃) and is closed when the sensor senses the heat in case of a fire. It is divided into round and square type according to its appearance.

Fire Damper (built-in high-tension spring) is closed quickly in case of a fire. It also maintains the elasticity of the spring due to the built-in high-tension spring.

Motored Fire Damper has built-in high-sensitivity heat sensor. It operates as an air volume control damper in normal times, but in case of fire, it is closed by sensing heat.

Backdraft Prevention Damper is a product that combines the functions of a fire damper and a backdraft damper (backdraft damper). Design registration (fire damper with backdraft prevention plate for air duct)
