3214JH3-195 ebmpapst 24V DC Axial Fan

Description

The ebmpapst 3214JH3-195 is a compact DC axial fan measuring 92x92x38mm. It is equipped with ball bearings and designed for air outlet over struts, rotating clockwise when viewed toward the rotor. This fan operates on a nominal voltage of 24VDC, with a broad operating voltage range from 18VDC to 26VDC. At its nominal 24VDC, it achieves a speed of 10500RPM, with a power consumption of 32W, a current draw of 1350mA, and provides a maximum free-air flow of 230m³/h. The maximum static pressure is 550Pa.

The fan’s housing and impeller are both constructed from plastic. It generates a sound power level of 7.5bel(A) at its optimal operating point (120m³/h @ 218Pa) and a sound pressure level of 66.0dB(A) at free air. The 3214JH3-195 features a 2-wire electrical connection, speed-controlled electronic functions, reversed polarity protection via a rectifying diode, and auto-restart locked rotor protection. The fan is designed for operation within ambient temperatures ranging from -20°C to 55°C, and its transport/storage temperature range is -40°C to 80°C. Electrical connection is made via wires, with a lead length of 310mm, using AWG 24 wires with 1.55mm insulation diameter. It has a Protection Class III and is approved by CE, EAC, UL (UL507), and CSA (C22.2 No. 113). The expected service life (L10) is 45000 hours at 40°C and 30000 hours at maximum temperature. This fan is ideal for demanding cooling applications in compact electronic enclosures and industrial systems requiring high airflow and static pressure, particularly well-suited for cooling telecommunications equipment, servers, networking devices, power supplies, and industrial control cabinets in environments with controlled temperature and humidity, where direct water exposure is avoided.
