Exhaust fan installation and maintenance: a kitchen fan is indispensable key kitchen equipment, it is recommended not to install in the ceiling as possible, to be installed in the engine room, the roof or exterior wall to facilitate maintenance of the place. Second, the kitchen fan because of long working hours in hot, humid, gas fumes. Regular maintenance is indispensable work. Point of failure: 1, resulting in greasy impeller blade curvature, angle deformation htf quality exhaust fan, air volume total pressure parameters decreased significantly htf exhaust fan quality clearance, reach the exhaust requirements. 2, the impeller oil stains cause impeller to lose balance, increased vibration, bearing damage. 3, harsh environments parts easily rust, damage the fan. Fire temperature exhaust fan: for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation. Able to run for 30 minutes or more first-htf exhaust fan at 280 ℃ high temperature conditions, medium temperature at 100 ℃ continuous operation 20 hours / times without damage, fire is the ideal necessary facilities. HTF series fire temperature exhaust fan for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation. Capable of continuous operation at 280 ℃ high temperature for 30 minutes or more, the medium temperature at 100 ℃ continuous operation 20 hours / times without damage, fire is the ideal necessary facilities. htf term supply exhaust fan, exhaust fan Anhui htf, rose by up Rui Rui electromechanical HVAC Electrical Equipment Factory. L Rui HVAC Electrical Equipment Factory (www.dzsrxfkt.com) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers.
