ebm-papst and the DV6300 diagonal compact fanDiagonal compact fans for high pressure and low operating noiseDiagonal 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 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 172mm 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 190mm and an installation depth of 51mm.the free-blowing air flow is up to 1100m/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 the older models at the same time 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. These fans are also highly suitable for the more fluctuating cooling air requirements of IT/telecommunications applications such as base stations, servers, etc or in power inverters for wind turbines.
Ebm-papst and their new 420J series of compact fans
High-performance compact fan with great efficiency
ebm-papst 420J line requires around 70% less power input and noise levels at 2-5 dB(A) lower than its predecessor model (depending on the operating point) and satisfies the company’s own high “GreenTech” standards. The much lower power input reduces the impact on the environment across the entire operating time. To achieve this, the aerodynamics and EC drive for the fan – which measures 40 x 40 x 28mm – has been newly developed. At the moment, this is available as a 12V version operating at various speeds. The A 24V version and environmental protection versions are set to follow in the near future. The properties of this new series makes it predestined for use in IT servers, routers or even compact frequency inverters and welding inverters.
