CFM-4020V-070-255-20 is a compact DC axial fan designed for efficient thermal management in space-constrained applications. This 40 x 40 x 20 mm fan operates at a rated input voltage of 5 VDC with an operating range of 3.5 to 6 VDC, delivering a rated speed of 7000 RPM (±15%) and an airflow of 8.9 CFM at zero static pressure. The fan features a 4-pole DC brushless motor with an omniCOOL™ bearing system, generating a maximum static pressure of 0.22 inch H2O and producing 25.5 dB(A) noise at 1 meter. With a maximum input current of 173 mA and power consumption of 0.87 W, the fan incorporates auto restart protection and is built with PBT (UL94V-O) material for durability. The device is rated for a life expectancy of 70,000 hours at 40°C and 65% relative humidity, making it suitable for cooling electronics, industrial equipment, and consumer devices requiring reliable, low-power thermal solutions.
