Role: In the event of a fire, the internal electric actuator opens outlet electric pressure delivery outlet, warm sense smoke or manual fire alarm will turn positive outlet, a positive pressure fan tower roof open automatically, on air shaft pressurized air, 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 that smoke does not spread in the region, 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 outlet stairwell positive picture, it does not have the front room of natural smoke. 3, closed refuge floors. Pressure delivery outlet air volume control and prominent structure as the name suggests, is a positive outlet use of advanced technology, a good place to smoke is the major equipment in the domestic market, the company produced a positive outlet by users favorite. Positive outlet for air volume control valve body architecture After 2 mm cold rolled galvanized sheet molding it to carbon dioxide gas welding or welding by ordinary Q235 plate processing; In addition, we also learned that it leaves coated with 1 mm cold rolled plate for corrugated zinc, two synthetic spot-square shaft inserted, or 2 mm G235 steel cold forming, punching chip interpolating axes or welding circular shaft. After the installation is completed pressure delivery outlet, test drive group is normal, too tight and does not appear to determine the fixed portion collision problems, identify problems and timely adjustments to the best you can. Little attention at the time of installation, it will avoid losses. Low carbon environmental protection, energy needs now set pressure delivery outlet, more and more diverse architectural style of the decoration, the original color profile is difficult to meet the needs of consumers, the emergence of color profiles. Today, we summarize the outstanding structural properties under pressure delivery outlet, we have to understand the specific follows: 1. pressure delivery outlet low profile, light weight, easy to install replacement. 2. pressure delivery outlet integrated integrated design, set the air hose, no partition filter and outside the box in one. 3. The pressure delivery outlet closed structure and leak detection by scanners, and high efficiency. The filtration efficiency overlay H10-U15 level, even the wind, the high level of cleanliness. 5. positive outlet HEPA filter, outside the box, duct and rings set of modular structure as a whole, flexible and convenient to install and use. 6. The filter unit between the frame with neoprene compression seals, using the card mounting block can be individually removable replacement, reduce operating costs.
