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 Product Name: Francis fan Product Code: SWF Description: SWF series mixed flow fan structural features 1, high efficiency, efficient wide area: The fan The use of advanced software and CAD systems through multiple objectives, performance, design and development of high-tech products indicates, application acceleration oblique meridional flow method (also known as mixed flow fan), compared with the same gauge pressure axial fans high air volume compared with the same machine No large centrifugal fan with high efficiency, high wide and so on. 2, compact, easy installation, reliable operation; The fan in the case of the same amount of wind, air pressure, and than axial or centrifugal smaller size, can be directly connected with the air duct, horizontal or vertical installation, also on the wall or stand mounted directly, while using the motor direct-coupled method, with the installation, operation, easy to use features. 3, low noise: the fan volute is specially designed to greatly reduce the volute noise. The unit amount of wind, air pressure unit operating conditions, A sound level can be reduced 2 ~ 3dB (A), while in the case of low speed, get a higher fan pressure. In the industrial and mining enterprises and senior civil ventilation system can replace the low-pressure centrifugal fan or an alternative high-pressure axial fan silencer without using a large number of measures. 4, using a wide range: The series points single-speed and two-speed two models, can pressure delivery outlet according to the previous use of different occasions room, change the angle of the wind turbine installation, changing the number of blades and conversion speed to other requirements. paiyanfenpaiyanfe Model Description: 1, fan performance properties listed in the table is the most efficient performance within range, according to the air volume is divided into five performance working points pressure delivery outlet before the face, according to prevail in the selection of the performance table. Fan factory is qualified products at rated air flow. 2, the wind turbine installation can be divided into horizontal and roof type, such as when to air flow, total pressure, dimensions and other properties have special requirements, our company will provide you with a separate design and production. 3, HTF-Ⅰ, HTF-Ⅱ represents pressure type fire temperature exhaust fan, leaf type axial flow type: HTF-Ⅰ (single speed) and HTF-Ⅱ (double speed) of two; HTF-Ⅲ, HTF -Ⅳ representation pressure fire temperature exhaust 4, HTF-X as a silencer fire temperature exhaust fan, the user can choose according to the actual needs of different species. 5, HTF-W series rooftop fire temperature exhaust fan, the user can choose according to actual needs retardant fiberglass hood or steel hood. 6, HTF-D as a low pressure type fire temperature exhaust fan. 7. Special Note: GYF and HTF series fan is like .S) overview, with the same machine number than the centrifugal fan large amount of wind, air pressure higher axial fans, and other characteristics can be axially mounted; low noise, low power consumption, efficient wide area, easy to install and use than the centrifugal fan, reliable operation. Features 1. Compact structure, easy installation, reliable operation; The fan than axial or centrifugal small size in the case of the same amount of wind, air pressure can be directly connected to the duct, horizontal or vertical mounting pressure delivery outlet Manufacturers, easy operation features. 2. Low noise: The fan casing is specially designed to greatly reduce the outflow of noise. In the unit amount of wind, air pressure unit operating conditions, than A sound level can be reduced 2-3dB (A), while in the case of low speed pressure delivery outlet, obtain higher fan pressure. In the industrial and mining enterprises and senior civil ventilation system can replace the low-pressure centrifugal fan or replaced without the need for a large number of high-pressure axial fan silencer measures. 3. Wide range of applications: This series points single-speed and two-speed two models, according to different occasions, changing the mounting angle of the fan, change the number of leaves and converting speed to its requirements.
