Diagonal fans are ideal for applications with strict requirements regarding air performance with high back-pressure and small installation space.
The new fans from ebm-papst's DV 6300 series 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, closed loop PWM speed control, and constant speeds over wide input voltage ranges.
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.
This is especially impressive considering that the scale of noise is logarithmic and 3dB(A) represents a typical halving of the audible noise.
A reduction of 8dB(A) therefore represents more than a halving and a halving again of the audible noise.
The DV6300 fan series is particularly well suited for applications with high endurance loads such as for motor frequency inverters and switch cabinets cooling, printing machines and heat exchangers.
The fans are also highly suitable for systems requiring multiple different operating conditions such as the cooling air requirements of IT and telecommunications, including base stations and servers, or in power inverters for wind turbines.
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. With an efficiency of 85 per cent for complete motor and electronics, the 350W motor is configured for a long service life at nominal output in all components.
