A product description SWF series mixed flow fans have the same number of the machine relatively large amount of wind centrifugal fans, axial flow relatively high pressure fans, and other characteristics can be axially mounted; low noise, low power consumption, efficient wide area, install and use than the centrifugal fan convenient, reliable operation. Two, SWF series mixed flow fans Features 1. Compact structure, easy installation, reliable operation; the fans than the axial flow or centrifugal duct directly connected with the small volume in the case of the same amount of wind, air pressure, horizontal installation or vertical installation, operation and convenient features. 2. Low noise: The fan casing is specially designed to greatly reduce the outflow of noise. Air volume in the unit, the unit under pressure working conditions than A sound level can be reduced 2-3dB (A), while in the case of low speed, get a higher fan pressure. In the mining industry, and senior civil ventilation system can replace the low-pressure centrifugal fan or replace the high-pressure axial fan silencer without requiring a lot of action. 3. Wide range of applications: The series points single-speed and two-speed two models, according to different occasions, to change the angle of the fan is installed, change the number of leaves and conversion speed reaches its requirements. Third, the mixing machine takes the wind flow above, features: HL3-2A Francis low noise, energy-efficient fans and Francis PYHL-14A low noise, energy-saving fire temperature exhaust fan, is between axial and centrifugal fans of A new fan between the same machine number than the centrifugal fan large amount of wind, air pressure than the axial flow fan high, with high efficiency, energy saving, low noise, easy installation. The main impeller fan, hairdryer, import collector, guide vanes, motors and other components. Meridian impeller has accelerated features twisted shaped leaves welded to the hub, the balancing test, speed test, with good air performance. Streamlined collector wind Jane connection with silencer function as a whole, built with guide vanes, with good air distribution, pressure stability. PYHL-14A type unique fan design, high-temperature closed built-in motor, arranged a special motor cooling system to reduce the ambient temperature of the motor. Second, Francis fan uses: HL3-2A mixed flow fans for ventilation, PYHL-14A Francis fire temperature exhaust fan can be used as high-temperature exhaust, dual ventilation, but also 300 ambient temperature normal operation 60 minutes for a tunnel underground garages, underground shopping malls, underground storage, and other high-temperature exhaust senior construction, fire is the ideal accessory products. By the institute and the user's choice, in case of fire, can quickly exhaust fumes, to ensure staff are able to secure access to essential fire safety facilities.
