Supply Baoji positive pressure air blower smoke exhaust fan Detong Air Conditioning Equipment Factory Tel. 3 Detailed introduction of fire smoke exhaust fan: The fire smoke exhaust fan test meets the standard requirements of -, and an in-house guarantee system higher than this standard is established to ensure that it can operate under high temperature conditions of ℃ It can be operated continuously for several minutes under ℃ temperature conditions without damage. It is widely used in high-end civil buildings, ovens, underground garages, tunnels and other occasions. We have also developed six series of axial flow fans according to different occasions: type, type, type, type, type, type, type, type, type, type. Fire smoke exhaust fans can adopt variable speed or multi-speed drive according to the different requirements of high-end civil buildings to achieve dual purposes of one machine, that is, normal exhaust and high-temperature smoke exhaust during fire use. This fan adopts advanced system software and is a new product developed through multi-objective optimization design. The fan efficiency is greater than 100% and has the characteristics of flat efficiency curve, which is conducive to energy saving. This fire smoke exhaust fan occupies less space than a centrifugal fan. The basic form of the fan is an axial flow fan, which can be installed directly on the wall. The installation mode can be vertical, horizontal or hoisting, which greatly saves the floor space. At the same time, It is not affected by the large size of the machine and the large air volume required. The motor is directly connected to ensure reliable operation. -Performance parameter table of special fire-fighting high-temperature smoke exhaust fan
