CFM-4020V-150-165-20 is a 12 VDC DC brushless axial fan from the CFM-40V series featuring a 40 x 40 x 20 mm frame with omniCOOL bearing system and auto restart protection. The fan operates at a rated speed of 5000 RPM (±15%) with an air flow of 6.3 CFM and static pressure of 0.11 inch H2O at rated voltage. It draws a maximum input current of 46 mA at 0.56 W power consumption, with an operating input voltage range of 4.5 to 13.8 VDC and a starting voltage of 4.5 VDC. The fan generates 16.5 dB(A) noise at 1 meter and is constructed from PBT material (UL94V-O) with a weight of 29 grams. This model is ideal for compact cooling applications in industrial equipment, telecommunications, and consumer electronics requiring reliable, low-noise thermal management with optional tachometer signal monitoring.
