RL65-21/12/2HP ebmpapst 12V 19W 97mm DC Centrifugal Fan

Description

The ebmpapst RL65-21/12/2HP is a high-performance DC centrifugal blower engineered for precision cooling in compact, high-impedance environments. Operating on a nominal 12 VDC supply (10.8 – 12.6 VDC range), this unit features a 4-wire interface with a PWM control input for intelligent speed modulation, reaching a nominal speed of 4900 RPM at 19 W. Within its 97.0 x 94.0 x 33.0 mm plastic housing, the blower utilizes a ball bearing system to deliver an airflow of 61 m³/h (35.9 CFM) and a static pressure of 390 Pa. Designed for versatile installation, it supports any shaft mounting position and maintains a service life of up to 92500 h (IPC 9591), ensuring reliable operation in mission-critical hardware from -20 °C to 55 °C.
