Mine press-in counter-rotating fan, he characteristics of reasonable structure, complete specifications, high efficiency, obvious effect of energy saving, low noise and long distance of air supply. According to the requirements of different ventilation resistance, it can be used as a whole machine and can be used in stages, so as to reduce ventilation power consumption and save energy. If the length of the roadway is less than 2000m, the air can be supplied normally without moving the fan, which reduces the labor intensity of the workers and saves the ventilation time. It is the ideal equipment for local ventilation in underground coal mines. At the same time, it can also be used in high-pressure ventilation applications such as metallurgy, nonferrous, gold, chemical industry, shipbuilding and ceramic industries.This product is mainly used as press-in type local ventilator in the underground coal mines. It is applicable to the local ventilation applications of mining working face and various kinds of chambers. At the same time, it is also applicable to the local ventilation applications in other mines and various kinds of tunnel ventilation.The composition of the model and its representative meaningTake FD?6.3/30×2 type fan as an exampleProduct parameter listSerial no.Machine no.Air volume (m3/min)Full pressure (Pa)Power (KW)13.5/4.4133-90715-13202.2×224/3111-56172-18001.5×234/4.4136-72251-18802.2×244/6150-86351-19563×255/8210-120331-25034×265/11228-132371-29505.5×275/15245-150380-35247.5×285.6/15274-164375-37507.5×295.6/22340-210405-441811×2105.6/30395-250450-447015×2116.3/30420-260413-495015×2126.3/37486-292513-513018.5×2136.3/44525-310600-526322×2146.3/60590-390760-580030×2157.1/60620-396603-645030×2167.1/74672-480800-650037×2177.1/90738-4001100-670045×2188.2/74630-270420-690037×2198.2/90654-380600-760045×2208.2/110790-550680-820055×2218.2/150964-546700-860075×22210/601170-814745-273330×2
