Detailed Product Description: | No power fan is pushing the use of nature's natural wind speed turbo fan rotation principle and the indoor and outdoor air convection, the air flow in any direction parallel to speed and into a bottom vertical air flow to improve indoor ventilation effect An apparatus. The fan no electricity, no impatient tone, long-term operation. Based on air flow and air flow principles of natural law, is set at the top of the rationalization of fiberglass roofing roof exhaust fan price can quickly exhaust hot air and polluted indoor air supply fiberglass roof exhaust fan, improve the indoor environment. Choice points: exhaust fans choose the main control parameters for temperature, air flow, total pressure, efficiency, noise, electrical power, speed and shaft power. Exhaust fan at medium temperature not higher than 85 ℃ conditions should be long-term normal operation. Exhaust fan shall ensure that: When the transmission medium temperature at 280 ℃ continuous working time 30min, and the temperature of the cooling medium is still continuous normal operation to ambient temperature. At rated speed in the work area, fans of the measured pressure curve and the instructions given in the curve should satisfy the following requirements: axial-flow exhaust fan in the prescribed pressure value corresponding to the deviation of ± 5 %. Centrifugal exhaust fan at a predetermined flow rate, the pressure corresponding to the deviation of ± 5%. A sound level than the exhaust fan noise limits in the description given operating point should be consistent with the provisions under the JB / T8690-1998 of. Exhaust fan can be an ordinary or special steel centrifugal exhaust fan axial fan. Exhaust fan specifications according to "fire protection design of tall buildings" in the regulations. The minimum air volume exhaust fan 7200m / h, the maximum air flow should not exceed 60000m / h (refers to a smoke partition of maximum air volume). Exhaust fan air flow should be required to increase airflow value of not less than 10% to 20% of the surplus amount. Pressurized smoke exhaust fan pressure value shall be calculated loop system is the most unfavorable, and to ensure that the value of the residual pressure in the stairwell 40 ~ 50Pa. The value of the residual pressure inside the front room, shared room, fire elevator room, refuge layer 25 ~ 30Pa. Fire exhaust fan should be consistent with the current standard JB / T10281-2001 "fire exhaust fan technical conditions." Fan exhaust system should be set individually. Exhaust fan should be in the same position or upper layer of smoke zone.
