Air flow and air flow introduced outside static pressure, pressure loss and noise Buying blower before, you should understand the fan speed. Noise is associated with the air volume and external static pressure chamber before the blower, both of which are very specific amount, is not connected with the fan speed. Fan blades and fan speed and motor manufacturer adopted related. Demand from wind blower cold and hot load performance to decide. Once decided, the blower unit and then to meet the occasion of the outside static pressure of aggregate demand. Outside static pressure is affecting a number of parameters, including the air space of the arrangement, duct length and type, construction elbow duct arrangement, the air diffusion characteristics of the mouth. A certain proportion of fresh air demand also has a dramatic impact on the blower. Working conditions [1], the power supply.
