Application of 250mm 24V 48V DC high efficiency industrial axial flow fans for telecom: 

The telecom axial fans were usually used for telecom base station. Axial flow fans for telecom is usually 250mm and the axial fan efficiency can be higher than 80%. Under certain temperature conditions (18 ℃ ~28 ℃), all kinds of electronic equipment in the telecom room can run normally for a long time. According to the temperature difference between indoor and outdoor and hot and cold air exchange, ventilation system to exhaust the air by the high efficiency axial fans. Under the premise of normal operation of equipment inside room, to achieve the purpose of effectively reduce the internal temperature of the room and also saving electricity. This axial fan can be also used in other equipments where ventilation and air cool is needed.
