Introduction This series low noise multi-wing type air conditioning use centrifugal fan, with enlarged blade width and reduced leaf blade quantity, has bigger air volume(capacity). Its rotational speed is lower, and with steady running performance and lower noise. Its structure is compact, thus easy to install and maintain. 1) Rotating ways It has two rotating ways-- laevogyrate (LG, counterclockwise) and the dextrogyrate (RD, clockwise) . 2) Installs form It can be installed with 0°, 90°, 180°, 270° four kinds of air outlet directions.
•Optional Parts: flexible coupling, variable inlet vane damper, damper, electric actuator, motor with variable frequency and speed regulation, frequency converter, soft starter for motor; •Impeller is adjusted by the static and dynamic balancing test. •Backward blades •Water cooled bearing house •Oil leak preventing design for bearing house •Long service life •Large air volume, low noise, high efficiency •Easy installation and operation •Superior service in customized design and production.
