The Easi-Air Range of roof mount fans include both single phase (240V) and three phase (410V) backward curved centrifugal impellors. Incorporating Solar and Palau external rotor style motors, the vertical discharge roof fans are constructed from sturdy sheet metal and can be powder coated upon request. For ease of access to the motor for cleaning and maintenance, the units include release latches, allowing the wind band to be easily and quickly removed. Bird mesh is available as an extra. The impellor assembly is dynamically balanced and every fan is run tested prior to leaving our workshop.
