Jiujiang power fan price Changzhou power blower manufacturers sunshine 1 curved fan blade best results of scientific computing, to strictly ensure the working condition taboo never let rainwater intrusion. Exhaust efficiency is high, as long as not less than 0.2 meters in the breeze or the indoor and outdoor temperature difference of more than 0.5 ° C, to light, to function effectively. 2, the central axis of a fine steps, so never deformed under high-speed operation of the fan blade of the turbine, which greatly improve the service life of the fan. 3, variable angle design of the neck can make the fan 0-22.5 degrees a slant under arbitrary installation, the installation works is very simple, ordinary people can be installed to complete within about thirty minutes. Power fan is the nature of the natural wind speed push fan turbine rotation and indoor and outdoor air, the principle of convection, any direction parallel to the air flow, acceleration, and converted to a bottom-up flow of air perpendicular to, in order to improve the indoor ventilation effect An apparatus. The fan is no electricity, no impatient tone, long-term operation. According to the the air natural laws and the principle of airflow, rationalization set in the top of the roof, the rapid discharge of hot air and polluted indoor gas to improve the indoor environment.
