» Design and Downloads


The casings are produced following the rotational casting procedure and are made of electrically conductible polyethylene (PE). The design allows removal of the motor with the impeller and the console without having to disconnect the casing from the duct system. The casing and stainless steel console are sealed to each other with an expanded PE sealing ring.


The consoles are made of stainless steel material no. 1.4301. The console supports the motor and the spiral casing and, at the same time, forms the back wall of the casing. For mounting the motor, a motor supporting plate is screwed onto the console.


Impellers of polypropylene with backward curved blades with high efficiency are used. The impellers together with the hubs are dynamically balanced at two levels according to the G2.5 quality level as per DIN1940.


Electrical connection

The electrical connection of the motor is done via the terminal box of the pre-assembled IEC standard motor.
