Role: In the event of a fire, the internal electric actuator opens the air, temperature sense smoke or manual fire alarm will turn positive outlet types, positive pressure blower tower roof opens automatically sent to the pressurized air shaft wind, 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 a positive pressure to ensure the smoke will not spread positive outlet specifications in this area, 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 1, does not have the natural conditions of the stairwell smoke, fire elevator room or shared room. 2, the use of natural smoke stairwell, it does not have the front room of natural smoke. 3, closed refuge floors. When installing the encounter, and how it should deal with pressure delivery outlet dew? When it comes to positive outlet pressure delivery outlet, we are most troublesome is the condensation problem when installing, I had the company of condensation problems, there is a good solution, we want to be very helpful. 1. Try to reduce the number of positive outlet door manufacturers, view the interior is not sealed from the outside world does not work; 2. Increase the air volume, the wind speed is adjusted to the highest level possible, or the regulator valve open as possible; 3. If for side outlet, will blow up the lateral louvers adjusted as to prevent condensation flow out after the blinds; 4. if able to do so, can the outlet end of the stick side with a thin layer PE insulation board. On the positive outlet spray a layer of hydrophobic material may be useful to avoid condensation!
