RL48-19/14
ebmpapst’s centrifugal fans are available with either forward‑curved or backward‑curved impellers. Forward‑curved centrifugal fans operate quietly and are equipped with a volute casing. Backward‑curved centrifugal fans offer greater design flexibility and do not require a volute. For centrifugal fans with an external rotor motor, the motor is housed within the impeller, which not only ensures optimal motor cooling but also enables an exceptionally compact design. The entire product range features both AC drive and eco‑friendly EC technology.
