Installation and maintenance: the kitchen fan is indispensable key kitchen equipment, recommended not installed in the ceiling, to be installed in the engine room and so on, roofing or exterior wall for easy maintenance of the place. Working kitchen fan due to prolonged high temperatures, humidity, smoke gases. Regular maintenance is indispensable work. Failure: 1, the impeller blade leads to oily curvature, angle deformation, air volume total pressure parameters decreased significantly, reaching less than exhaust requirements. How it works: the usual two-speed high-temperature exhaust fan at low speed in order to meet the exhaust air flow, when the fire broke out brand exhaust fan, temperature exhaust fan in the cabinet under the joint control of the role of automatic high-speed operation, in order to meet the needs smoke, meanwhile, No action exhaust pipe smoke damper fire smoke damper and smoke partition makeup air and exhaust pipes were up wind, automatic smoke damper other smoke partition in the role of automatic linkage control cabinet closed when the flue gas temperature reaches 280 ℃, automatic smoke damper will automatically close, exhaust fan and make the fan automatically stop. storey 3.5 m quality exhaust fan, a total of five smoke partitions, fire design uses the air conditioning and ventilation systems and smoke exhaust system combined approach. selected two-speed high-temperature exhaust fan, high speed exhaust volume of 63500 m3 / h, low exhaust volume of 35400 m3 / h, blowing fresh air and makeup air unit an amount of 32000 m3 / h, all with automatic smoke damper smoke damper Products; Fire exhaust fan in the production of pipe installation it can be directly connected with wind or wall mounting, and it can be installed in the form of vertical type or horizontal quality exhaust fan, so it saves area in a large extent. In addition, it also can run more than 60 minutes continuously under high temperature 300 ℃ conditions, at a temperature of 100 ℃ continuous 20 hours / times without damaging the exhaust fan, it is widely used in high buildings, oven, underground garage, tunnels and other occasions. Exhaust fan fire a wide range: it can according to the different requirements of senior civil use of variable speed or multi-speed drive form, in order to achieve one machine (ie, when used through ventilation and fire high-temperature exhaust) purposes; leaf type divided axial flow (HTF-Ⅰ, Ⅱ) and mixed flow (HTF-Ⅲ, Ⅳ), so fans of the series has a wide range of performance parameters. Special attention is required when users require a higher noise, it can be made into a silencer-type fan. Quality exhaust fan, Chen Yu-conditioning management with the world, Leshan City exhaust fan by Wu Chen-yu air-conditioning Limited. Wu Cheng Chen-yu air-conditioning Co. (www.wccykt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs .
