  • product introduction:The HTF series fire-fighting high-temperature smoke exhaust fan is a national "Xinghuo" project product. It has excellent performance, good high temperature resistance, high efficiency, less space than centrifugal fans, and easy installation. The fan test meets the requirements of GBJ45-82 fire protection standard, and establishes an enterprise internal control assurance system higher than this standard. It can run continuously for more than 30 minutes under high temperature conditions of 280°c. It is widely used in advanced civil buildings, ovens, underground garages, tunnels, etc. ; The fan can be driven by variable speed or multi-speed according to the different requirements of high-level civil buildings to achieve the purpose of one machine and dual use (that is, common ventilation and high temperature exhaust during fire fighting). If the user has high noise requirements, it can be Manufactured into a silencing fan. The actual measurement of the fan products shows that the fan efficiency is greater than 80%, and some large models are greater than 85%, and have the characteristics of a flat efficiency curve, which has the effect of high efficiency and energy saving. The fan is easy to install and occupies less space than a centrifugal fan. The fan can be directly connected to the air duct. The installation form can be vertical or horizontal, which greatly saves floor space.
