Our external rotor axial fan with low noise multi-blade centrifugal impeller, and the precision balancing correction, for supporting the outer rotor motor, external rotor axial fan casing made noise muffler design. External rotor axial fan designed for insulation and new air ventilation switch design. Optimized design outer rotor axial fan is the use of air forced air cooling. External rotor axial fan can be widely used in building indoor ventilation and exhaust cooling equipment use. External rotor axial fan Features: 1, external rotor axial fan with a small size, low noise, appearance and other characteristics. ? 2, stable external rotor axial fan aerodynamic performance, to ensure that the network due to changes in working conditions and produce sufficient exhaust volume, external rotor axial fan ventilation require longer meet the ventilation passage. 3, external rotor axial fan air volume, high pressure and die molding, block adjustable structure, parts easy to disassemble. 4, external rotor axial fan grille with a high-quality iron wire drawing, compact structure, beautiful appearance, easy installation, long life. 5, the outer rotor centrifugal fan and reasonable structure design flexible lead direction. 6, the outer rotor centrifugal fan centrifuge superior performance, low noise, low vibration, high level of protection so as to external rotor axial fan for a long time in a relatively harsh environment running smoothly to provide a reliable guarantee. 7, the outer rotor centrifugal fan with optimized design, with high efficiency, can produce significant energy savings I supply centrifugal fan, fan and matching control products, centrifugal fans made of high quality galvanized steel and aluminum materials, and reliable processing craft, under reasonable conditions to maintain, extend the service life of the centrifugal fan. Outer rotor centrifugal fan itself has a small, energy-saving, high efficiency, low noise, vibration small, long life, large air volume and so on. Outer rotor centrifugal fans are widely used in purifying air conditioners, room air conditioners, dehumidifiers, whole heat transfer machine, compression refrigeration, duct fans, new fans, air curtains, window natural ventilation and other fields.
