Product Description

Product Description

Fire damper usually opens on the delivery and return ducts of ventilation and air conditioning systems.
* Once the fire is prevented, when the gas temperature in the pipeline reaches a certain temperature and shuts itself off, the requirements of smoke discharge and fire integrity can be met within a certain time. It acts as a smoke-proof layer.
* Exhaust damper is used at the suction inlet of exhaust system pipe or fan. It is usually enclosed and meets the requirements of air leakage. When the fire or need to exhaust smoke, manual and electric valves open, exhaust smoke.

* Fire valves are usually installed in the air ducts of ventilation and air conditioning systems.

 

 

Discover the superior functionality of our HVAC Automatic Electric Volume Damper, a sophisticated solution designed to enhance airflow management in office buildings. This innovative damper remains open by default and allows for precise control with its manually adjustable blade angle, spanning a full 0 to 90 degrees. In critical situations such as a fire, the damper features an automatic safety mechanism: when the duct's gas temperature reaches 70 degrees, a fuse protector melts, triggering the damper to close swiftly under spring tension. Uniquely engineered, this damper can also be operated via DC24V electrical control, distinguishing it from conventional fireproof dampers. It is expertly crafted to meet the rigorous smokeproofing and fireproofing demands of ventilation and air-conditioning systems, making it an indispensable component for vital buildings where manual resetting is not an option.
