The SKB axial fan measures 40x40x20 mm and operates from a 12 Vdc supply. At 7000 rpm it delivers an airflow of 19.4 m³/h while producing 31.4 dB of noise. The body and rotor are both moulded from plastic reinforced with fibreglass, providing mechanical strength while keeping weight to 23 g.

Bearing support is via bushings, making this fan suitable for applications where cost and low noise are priorities over extended high-temperature operation. The two-thread output and 250 mm wire length allow straightforward connection to standard fan headers or direct wiring.
