Description
EFB0424MD Delta 40x40x20mm Ball 24VDC 7.17CFM(0.203m3/min) 0.218inchH2O(5.54mmH2O) 24.0dB(A) 1.20W 6300RPM 2wire leads fan
Delta EFB0424MD is a DC brushless axial flow fan with a nominal voltage of 24VDC (operating voltage 14.0-27.6VDC), maximum input current of 0.08A, power of 1.92W, and rotational speed of 6300RPM. It delivers a maximum air flow of 0.203m³/min (minimum 0.176m³/min) and maximum static pressure of 5.54mmH₂O (minimum 4.18mmH₂O), with an average acoustic noise of 24.0dB(A) (maximum 27.0dB(A)). Measuring 40.0×20.0×10.0mm and weighing 33g, the frame and impeller are made of UL 94V-0 flame-retardant plastic, equipped with double ball bearings and rotating clockwise when viewed from the nameplate side. It uses UL 1007-F AWG#24 leads (red for positive, black for negative), operates at -10°C to 70°C, stores at -40°C to 75°C, and has a working humidity of 5%-90%RH. With locked rotor protection (preventing fire within 96 hours of lock-up) and reverse polarity protection, it has a lifespan of 70,000 hours at 40°C and 15%-65%RH, suitable for low-power cooling in small electronic devices.
