Axial roof fan, the installation we should first calculate the ventilation rate throughout the workshop to be needed to achieve the full workshop optimum ventilation and cooling effect, then prepare the installation of the program, rather than the one up on the busy installation, to final only to find roof axial fans, too much or too little installation. When installing as possible to the shop window at the Zhangjiakou without power fan, window outside environment is broad vision, without power fan specifications, can not have a drainage ditch, smelly garbage tank and other contaminated sites. Noise machinery and equipment raw shop is relatively large, it is best to install a roof axial fan with remote control function, so when not in use can be automatically shut down, the bad when you can automatic alarm. There are a lot of machinery and equipment production plant built with a lot of sophisticated equipment, the installation of roof axial fan, be sure to take into account the safety of the workshop equipment, thus giving the roof axial fans, with shutters to avoid the workshop stolen property, plant without power Fans, lost items. ANIMAL exhaust air out the room pressure falls, indoor air becomes thin, livestock characteristics form a negative pressure zone, air flows into the interior due to the pressure difference between the compensation. In practical applications, industrial plants, livestock centrally installed on the plant side air intakes in the plant room on the other side, the ball-type non-power fan, air from the intake port to livestock fan convection hair. In this process, animal husbandry fan near the doors and windows remain closed, forcing the air to flow from the inlet port side of the shop windows compensation. Air lined up orderly by the intake port flows into the workshop, from workshop to flow through, the animal husbandry and the fan discharge plant. Ventilation thorough, efficient, ventilation rate can be as high as 99%. Through specific engineering design, according to need to design ventilation rate and wind speed, any fever, harmful gases, dust can quickly exhaust smoke shop, any-time ventilation can solve the problems of poor. From a few seconds to turn on the fan for ventilation effect. _ Pig without power fan ventilation Flextronics (Online) _ Zhangjiakou without power fan ventilation equipment from the Flextronics Liaocheng Limited.
