Critical Applications: Fire Safety

Life Safety Products

Building codes provide guidelines and requirements for the installation of fire, smoke, and combination fire/smoke dampers. These codes are crucial for ensuring the proper function and effectiveness of these dampers in containing the spread of fire and smoke within buildings.

Combination Fire/Smoke Dampers

Combination fire/smoke dampers are low leak damper and actuator assemblies that have passed the UL555 and UL555S test requirements.

United Enertech offers a range of combination fire/smoke dampers to address a variety of applications and requirements, including our two featured models, the F/S-3V-I and F/S-AF-I.
