EM-DUO

Half radially redundant and insulated fan with insulated casing.

Variable mounting position, horizontal and vertical mounting possible. For easy mounting on pipes, the connecting pieces are equipped with a lip seal. Casing in galvanised sheet steel, sound-insulated. The removable cover makes it easy to remove the fans. With integrated mounting bracket for easy installation. The significant reduction of flow losses also minimises noise generation and, in combination with the vibration-optimised construction, results in a quiet ride.

Integrated ETAMASTER diagonal fans with three-dimensionally shaped blades and a three-dimensionally shaped diffuser downstream. This results in the highest possible aerodynamic efficiency. The impeller is balanced in two planes according to G6.3 DIN ISO 1970. Highest efficiency, electronically commutated permanent magnet motor (EC motor). The EC technology allows the ETAMASTER to operate very efficiently, even at partial load. The motor is protected in the hub area and does not interfere with aerodynamics. The internal electronic temperature monitor protects the motor against overload. Electrical connection via terminal box integrated in housing.
