Structure T35 series axial fan through simulation studies to determine the turbine airfoil axial fan square, using a cylindrical hub structure, the motor has been modified design wall axial fans, the structure reduces the flow loss axial fans, thus making the fan efficiency is calculated according to the outlet area of ??a circle up to 77 percent, according to exit the ring area calculation increased to 89.5%, lower than the A sound level of 3.6 dB. T35-type axial fan by the impeller diameter is divided into 13 machine number, in order of priority is: №2.8,*,3.55,4,4.5,5,5.6,6.3,7.1,8,9,10,11.2. Each gauge is divided into 15 °, 20 °, 25 °, 30 °, 35 ° and other five kinds of blade installation angle. Axial fan models; SF low noise axial fan has a smooth, streamlined surface, smooth operation and low noise axial fan, high efficiency, low noise, and other advantages of energy province. SF series fan according to the requirements of sub-pipeline, fixed, wall, four kinds of job type, job type of four, divided by the impeller diameter 12 gauge. Air volume range: 1630 ~ 41020 m3 / h Total pressure range: 135 ~ 79Pa speed range: 2900 ~ 960r / min Power range: 0.12 ~ 7.5kw portable Axial Fan | Chen Yu-conditioned factory outlets (certified) | Xingtai axial fans by Wu Cheng Chen Yu Air Conditioning Equipment Co..
