ebm-papst 4100 NH7 - S-Force Series Axial Fan, 48 V dc, DC Operation, 500m³/h, 90W, 119 x 119 x 38mm

The increased power density of electronic components means that devices producing a high level of waste heat are more tightly packed than ever before. S-Force fans dissipate heat with airflow levels of up to 950m³/h at system pressures of up to 1200 Pascals. At full load (approximately 14,000rpm) they provide up to 100% more output than their predecessors but work within a wider airflow range.
