Diagonal compact fans for high pressure and low operating noise

Electronics are used to regulate the motor according to temperature and to monitor the filter condition

Diagonal fans are ideal for applications with strict requirements regarding air performance with high backpressure and small installation space. The new fans of the DV 6300 series from ebm-papst St. Georgen now go a step further. Besides improved blower output, the fans with electronically regulated S-Force motor also offer additional functions such as temperature regulation, active motor cooling and filter monitoring with a signal output to indicate when a filter change is needed. The fans have a diameter of 172 mm on the suction side, making them exactly the same size as the DV 6200 range. On the pressure side, the aerodynamically revised design has a diameter of 190 mm and an installation depth of 51 mm. The free-blowing air flow is up to 1100 m/h3, the pronounced pressure saddle is up to 750 Pa. At 83.5 dB(A), operating noise in the high-pressure range is about 8 dB(A) quieter than older models at the same operating point. That is due to various factors, one of them being a flange with noise-optimised links. With an efficiency of 85%, the 350W motor is configured for a long service life at nominal output in all components. That makes the new fan series particularly well suited for applications with high endurance loads, e.g. for motor frequency inverters and switch cabinets cooling, printing machines and heat exchangers.

The fans are also highly suitable for the rather more fluctuating cooling air requirements of IT/telecommunications applications such as base stations, servers, etc. or in power inverters for wind turbines.
