2218F/2TDH40R-225

The 2218F/2TDH4OR-225 is a DC axial fan by ebm-papst featuring ball bearings, counterclockwise rotation, and air discharge over struts with flexible mounting in any position. Its mechanical specifications include 200×200×51mm dimensions, 220mm diameter, 1.06kg weight, a metal housing with a plastic impeller, and AWG20 wires (red for +UB, blue for -GND, yellow for CONTR, white for Tacho) with plug connections. Electrical parameters cover a 36–72VDC voltage range, 76–108W power consumption, 1.5–2.1A current, and up to 6500rpm speed at 48VDC nominal voltage, supporting PWM (1–10kHz frequency, typical 2kHz) and 0–10V analog voltage speed control. It includes reverse polarity protection (residual current ≤5mA), auto-restart for blocked rotor (3s/10s cycle), an inrush current limiter (2s start-up delay), and a Littelfuse 10A fast-acting fuse. Aerodynamically, it delivers 1220m³/h max. free-air flow and 1170Pa static pressure, with an optimal point at 1200m³/h@44Pa and 74dB(A) sound pressure level. Environmental adaptability includes -20°C~65°C operation, -40°C~80°C storage, compliance with DIN EN 60068-2-30 cyclic humidity tests, pollution degree 2, and vibration/shock resistance per IEC 60068 standards. Certified for EAC, UL, VDE, CSA, and CCC with protection class I, it has >10MΩ insulation resistance and L10 service life of 70,000 hours at 40°C (117,500 hours per IPC 9591), suitable for variable-speed heat dissipation in industrial ventilation and high-heat equipment.
