Products; fire exhaust fan installed in the production of it can be directly connected to the wind pipe or wall mounting, and it can be installed in the form of vertical or horizontal, so it saves area in a large extent. In addition, it also can be run continuously at 300 ℃ high temperature for 60 minutes or more, under 100 ℃ temperature conditions for 20 hours / time is not damaged, it is widely used in high-level civil, oven, underground garages, tunnels and other occasions. Exhaust fan fire wide range of applications: it can be based on different requirements of senior civil construction, the use of variable-speed or multi-speed exhaust fan wheel drive form, in order to achieve one machine (ie, when used through ventilation and fire temperature exhaust) of purpose; leaf type into Axial (HTF-Ⅰ, Ⅱ) and mixed flow (HTF-Ⅲ, Ⅳ) htfc exhaust fan, so fans of the series has a wide range of performance parameters. Require special attention to the noise when users are higher, can be made into a silencer-type fan. Fire temperature exhaust fan, both for the various types of building fire smoke exhaust fans, but also for a variety of construction, civil air defense projects, underground railways, mines, tunnels and other smoke and exhaust. Other notes temperature of the fan motor is designed with special cooling systems. Main duct medium temperature 280 ℃, it can run more than 30 minutes continuously. ≤150 ℃ when long-term continuous operation. 1. The small size and lightweight light with the same amount of wind centrifugal fan less two-thirds of the space. Reduce the weight more than half. 2. Simple structure The fan consists of five main parts. ① ② impeller motor cycle air cooling system ③ ④ guide vanes, inner tube ⑤ outer cylinder. Disassembly and easy maintenance. 3. easy to install the fan according to the requirements of building construction with horizontal and vertical hanging installation.
