DV Fans are ideal for high density applications

Designed to provide higher air pressure and higher airflow characteristics within a standard footprint, Papst's revolutionary DV5200 series fans will allow significant advancements in applications where downsizing and increased power densities are an intrinsic element of system design.

Achieving this unique combination with the DV5200 is a result of Papst's innovative technology that uses a diagonal venturi (DV). The venturi of the fan is conical shaped as opposed to cylindrical, with the fan hub following the same profile thus greatly increasing the air pressure characteristics at the exhaust side of the fan.

The result is a fan that is suitable for applications where due to compact system architecture and high component density, airflow is often severely restricted - for example in Compact PCI applications. The back pressure in such systems would normally create problems for standard axial fans of this footprint size. Not so the DV5200 which is able to achieve a flow rate of 150m3/h at a static pressure of 130 Pascals. These figures are approximately twice the performance levels attainable from a similarly sized axial fan, but the product will also operate at up to 250 Pa.

The DV5200 range comprises three models for use at 12, 24 and 48VDC; all measuring a compact 127 x 127 x 38mm. Featuring an electronically commutated external rotor motor and fully integrated commutation electronics, the fans have electronic protection against reverse polarity, blocking and overloading.

Running at their nominal speed of 5,000min-1, all three models in the DV5200 range consume 20W of power, offer a service life of 70,000 hours at 40°C, and will operate in a wide temperature range of -20 to +65°C.

For robustness, the fans feature a metal fan housing and an impeller of fibreglass reinforced plastic for low mass. Electrical connection is via twin AWG22 leads that are stripped and tinned for ease of assembly.

Meeting the demands for increased performance in densely packed electronic equipment, Papst's DV5200 fans will find favour with those requiring mission critical deployment such as in server, data storage, telecomms, power and ISP applications.
