6318/2TDHHP ebmpapst 48V 1.4A 67W 172mm DC Axial Fan

Description

The ebmpapst 6318/2TDHHP is a high-efficiency 48V DC Axial Fan featuring a 3-phase fan drive designed for exceptionally smooth operation and high energy efficiency. This unit operates within a wide voltage range of 36-72 VDC, delivering a powerful airflow of 710 m³/h at a rated speed of 7000 RPM. The fan’s robust construction includes a die-cast aluminum housing—equipped with a grounding lug for an M4 x 8 Torx screw—and a 5-blade impeller made of glass-fiber reinforced PA plastic. At a nominal power consumption of 67 W (wide open) with a current draw of 1.4 A, it is engineered for heavy-duty industrial environments, offering a service life of up to 62,500 hours at 40 °C. Integrated with a speed signal (Tacho) and control input, and protected against reverse polarity and blocked rotor conditions, the 6318/2TDHHP is a mission-critical thermal management solution for high-end telecommunications, power electronics, and server infrastructure.
