Fire smoke exhaust fan is mainly used for industrial and civil construction and civil air defense projects, usually also be used for indoor ventilation. Motor with high temperature swf positive pressure blower and a cooling air circulation system positive pressure blower, long-term operation at 100 ℃ medium gas can be smoothly transported 280 ℃ smoke up to 40 minutes or more. Horizontal, vertical, cabinet, three types are available. When dual exhaust ventilation, optional two-speed motor, low speed ventilation, high speed exhaust. Francis fan using advanced three-dimensional flow model design, but also has a large flow axial fans and centrifugal fans high-pressure characteristics, small size, high efficiency, easy installation, saving space for a variety of situations in the pipeline pressure ventilation. Oblique flow fan glass steel and steel two mixed positive pressure blower, both the centrifugal fan and axial fan pressure coefficient flow coefficient characteristics of high efficient wide area, low energy efficiency, noise, ventilation can be directly connected in series with the pipeline, easy installation, saving space, without a fan room paiyanfengjpaiyanfeng, GXF series of oblique flow fan Overview GXF series of oblique flow fan is the country's "Spark" Project products. GXF oblique flow fan is a new energy-efficient low noise oblique flow fan positive pressure blower manufacturers, oblique flow fan centrifugal fan flow is greater than the total pressure is higher than the axial fan, smaller than centrifugal fan. The fan was studied through simulation machine, using a new leaf type and leaf has been a greater flow and pressure, improving the efficiency of the fan. Widely used in industrial and mining enterprises, hotels, restaurants, museums, sports and other ventilation system. GXF series of oblique flow fan impeller diameter divided by 400-1400mm fourteen kinds of specifications, by type A, B, C, D, S five types were fifty-eight machine number. Wind capacity from 3000 ~ 90000m3 / h, the total pressure from the 185 ~ 2500Pa; so give the design department and user units provide adequate selection criteria. Features: excellent high temperature performance, high efficiency, easy installation, reliable operation (to produce single-speed, two-speed, frequency and stepless, rooftop exhaust fan fire and explosion Fire-type special fan) and obtain fire product license. Uses: High-rise buildings, oven, tunnels, underground garage and special industrial and mining enterprises and other fire temperature exhaust, exhaust. Specifications: Fan diameter: φ350 ~ φ1500mm air volume: 3350 ~ 93800m3 / h Pressure: 280 ~ 819Pa Fire positive pressure blower, blower where the good, given away by the positive pressure blower fan air-conditioning Equipment Co., Ltd. Shandong GREAT. Fire positive pressure blowers, blower where the good, positive pressure blower is set far in Shandong GREAT Fan Air Conditioning Equipment Co.
