Centrifugal Fans: ebm‑papst’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, while backward‑curved models offer greater design flexibility and do not require a volute. For centrifugal fans with an external rotor motor, the motor is integrated within the impeller, ensuring optimal cooling and enabling an exceptionally compact design. The entire product range features both AC drive and eco‑friendly EC technology.
