04 July 2003 High air pressure and airflow fans Higher air pressure and flow are provided within a standard footprint by Papst’s DV4112 series of fans. This advance in performance is said to have been obtained through the combination of Papst’s Variopro technology and its diagonal Venturi design. The latter feature sees the use of a conical, rather than cylindrical, Venturi. Fan blades, meanwhile, follow the same profile, increasing pressure. Running from a 12V dc source and consuming 23W, the DV4112 runs at 6000rpm, can operate against a static pressure of 300Pa and provides an airflow of 275m3/hr.
