Features galvanized sheet galvanized sheet suction fan suction fan is a new ventilation equipment, are axial fans, because the fan frame made of galvanized sheet steel, works by using a negative pressure ventilation, to air circulation, ventilation and cooling purposes, it is known as galvanized sheet suction fan. Galvanized sheet suction fan with a wind capacity, low-power, low-speed, low noise characteristics. Galvanized sheet suction fan is the use of negative pressure ventilation, ventilation and cooling air flow design principle, when the fan started working, use large blades rotate quickly indoor pollution, heat, hot air drawn from the outdoors, at the same time Let indoor and outdoor air to form a huge pressure, the indoor air becomes thin, forming a negative pressure zone, when fresh outdoor air due to the pressure difference between the natural flows into the indoor compensation. In practical applications, galvanized sheet suction fan centrally installed in the plant side air intakes on the other side of the room, the air from the intake end galvanized sheet suction fan convection exhaust ventilation. In this process, galvanized sheet suction fan near the doors and windows remain closed, forcing air to flow from the inlet port side of the shop windows compensation. Air from the air inlet into the room, from the room at a certain wind speed flows, galvanized by the position of the exhaust suction fan is installed outdoors. Galvanized sheet suction fan 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.
