Fire temperature exhaust fan, both for the variety of building fire smoke, 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 ℃ when the exhaust fan can be more than 30 minutes of continuous operation. ≤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. Power three-phase 380V, 50HZ install and use: 1) can be vertical, horizontal and hanger installation. Fan base must naturally be combined with basal plane, and not to beat coupling force base, the weight of the pipe shall be applied to the turbine components. 2) should be carefully checked before installation whether the impeller and the casing due to shipping damage and deformation, and if so, should be repaired before installation. 3) Check the connecting bolts are loose kitchen exhaust duct fans, motor insulation is good, whether or hinder the rotation of objects within the fan duct. 4) To install the fan after commissioning, abnormal rub, touch, and vibration to be excluded immediately.
