A robust range of ‘backward blade’ centrifugal fans, constructed from heavy-gauge steel plate, with a typical energy efficient of 88%, designed for the transportation at medium pressure of light/medium particulate materials, including dust and powder.
Each fan set is complete with a continuously rated, 50 Hz, 3 phase, TEFC electric motor (2.2kW – 22kW) and uses a statically and dynamically balanced twelve backward bladed steel impeller, which provides improved efficiency with stable and vibration free performance at lower sound output.
