Positive pressure blower and general axial fans different? In fact, positive pressure blower from the structural point of view that is outside the normal axial fans, positive pressure blower is to escape corridor air fan, at the time of the accident to escape corridor positive pressure air blower roof, which will help to escape, but to send When the pressurized air in the corridor, that corridor pressure higher than other places, the smoke will not cause suffocation infiltrated in order to ensure safety. Positive pressure blower is delivered fresh outdoor air. Positive pressure blower in the event of a fire, can keep the air inside the corridor positive pressure state, when there is no fire, usually positive pressure blower can be used as a normal axial flow ventilation machine. Positive pressure blower material generally choose glass, steel, carbon steel, iron, galvanized iron sheet, purchase, please contact us, for your dedicated service. Pressure delivery outlet functions and parameters: usually normally closed, electric, manual opening. Output on the start signal. Manual reset closed. 280 ℃ temperature sensor operation, the valve is closed again. The use of thin body, reduce operating box size, increase the effective area of ??the ventilation exhaust. Pressure delivery outlet main technical parameters: Operating voltage / current: DC24V / 0.5A. Leakage Rate: 290m3 / m2 · h≤700 (when pressure 1000Pa). Temperature sensor operating temperature of 280 ℃. Positive pressure blower role is to point escape corridor air supply fan. It outdoor air pressure into the interior. When the building is on fire gxf positive pressure blower, will produce a lot of smoke, carbon monoxide and other toxic gases and block line of sight, through positive pressure blower air to escape the fire stairs, indoor smoke can not reach the stairs, but when the air corridor positive pressure, high pressure means that the corridor than other places, the smoke does not infiltrate to cause suffocation, in order to ensure security, to create the conditions for people to escape. Positive pressure blower generally installed on the building roof. Positive pressure blower is pointing escape corridor positive pressure air blower fan, air corridor to escape at the time of the accident, which will help to escape, while a positive pressure in the supply air corridor, that corridor pressure than the other Local smoke will not cause suffocation infiltrated in order to ensure safety. Roof positive pressure ventilation fan blower _ (certified) _ positive pressure blower is provided by the Texas Huaxin air-conditioning plant. Texas Watson conditioning plant (www.wchuaxin.com) (www.wchuaxin.com) Shandong Dezhou, heat, refrigeration and air conditioning equipment leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
