Pressure relief dampers do not immediately … high (305mm x 305mm) versus a competitor’s equivalent 12 in. The commercial dampers provide low pressure openings with exceptional pressure drop performance, while the industrial line includes heavier gauge materials to withstand the high velocities and back pressures associated with these applications. Functional description Pressure-relief dampers open and close automatically. ARK2 For the prevention of excess pressure in rooms read more. A pressure relief damper is developed with an elevated and adjustable start-open pressure while providing the backdraft function. A relief blade reacts to positive building pressure by forcing gravity operated relief dampers open; allowing excess air to exit the building. The air isn't able to flow into room if the indoor pressure is smaller than outdoor pressure. Products cover a wide variety of applications ranging from life safety to maintaining the control of outside air. Pressure Relief Dampers for low opening pressures at low range of volume flow KL-ETM. %%EOF When the ventilation system is on, the blades of the non-return damper are held in the open position by the airflow. Contact us For further information. TROX Easy Product Finder Fast. Pressure relief dampers also prevent backdraft air flow. Pressure Relief Dampers for high opening pressures, with switching function KL-EM. high (305mm x 305mm) damper. The channels are mechanically fastened and welded at each corner. Should The sliding weight can be adjusted to open when a certain pressure is reached. Non- return damper or gravity-operated damper, counter balancing damper, Self-balancing or Backdraft damper. 0 DuroZone Pressure Relief Dampers are used to automatically relieve Duct Systems of the pressure build up created, as zones satisfy and dampers close. When the system is cooling both floors, all of the zone dampers are open so that air can flow everywhere. The blades are kept closed by magnets. The pressure loss through any damper is a function of the entering flow profile, the free area ratio, F, of the open damper area to that of the damper frame or wall area, the geometry of the damper installation, and the exit conditions as air leaves the damper. The damper inside either allows or prohibits air from entering the bypass duct, depending on the situation.
