The existing sad world statistics show that a large percentage of people die in fires in closed rooms as a result of poisoning by products released during combustion (smoke, volatile chemically active substances). Increase security:
- Visitors to shopping centers and public places.
- Office workers and residents of apartment buildings.
- Clients of municipal and commercial organizations.
- In children's and educational institutions.
Allow special systems, as well as smoke exhaust fire dampers . They are installed directly in ventilation shafts and ducts. Depending on the scheme laid down by the architects of a particular building for the implementation of forced ventilation in them, such valves can perform one of two functions:
- Seal the duct hermetically to prevent smoke from spreading along it.
- Open an additional shaft for urgent and quick removal of combustion products from the premises where the fire has occurred.
The valves are triggered to close or open the sash that blocks the ventilation duct on a signal from a triggered fire alarm or when they are activated in manual mode.
Valve assembly with damper and actuator
You can order and purchase a smoke exhaust fire damper complete with a system that includes in its structural diagram a valve that hermetically closes the shaft channel, as well as a drive for closing or opening it when the valve device is triggered. Various options and modifications are presented on the website of the company "Merkor-PRUF", which carries out their development and production. For consultation on the resource, the option of contacting the manager of the enterprise is provided, who will answer all your questions.
