The main functions, features editor usually normally closed, electric, manual opening. Output on the start signal. Manual reset closed. 280 ℃ temperature sensor operation, the valve is closed again. Using thin body, reduce operating box size, increase the effective area of ??the ventilation exhaust. Role: In the event of a fire pressure delivery outlet, its internal electric actuator opens outlet, warm sense smoke or manual fire alarm will open, positive pressure blower tower roof opens automatically pressurized air to air shaft pressure delivery outlet face, the front room of the stairs by a steady stream of pressurized air outlet will air on the front chamber, the front room to maintain positive pressure delivery outlet Atlas ensure smoke will not spread in the region are outlet pressure mounting height, while giving space to escape. When the temperature is higher than 280 ° C were no longer escape the possibility of its internal fuse will blow, air automatically shut down to prevent the fire from spreading. Application: National high-rise building fire smoke design specification, these parts should set up a separate mechanical exhaust system pressure delivery outlet type, pressure delivery outlet, rich ventilation equipment from Dezhou Plumper ventilation plant. Dezhou Plumper ventilation plant (0) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Plumper ventilation equipment into the brilliant and you work for a better future!
