|---|---|
| Speed | 3650 rpm |
| Voltage | 12 V DC VAC |
| Motor frame | The unit is designed as a built-in assembly and is mounted with screws of strength class 8.8. The screws must be secured against accidental loosening, for example with self-locking screws. The installation position is optional and the unit weighs 0.7 kg. The fan must not be subjected to stress at the fastening to the substructure, and when connecting to air ducts, vibration-isolating elements such as compensators should be used. |
| Casing | Rotor painted black, metal plate painted black |
| Impeller | The fan impeller has 7 blades and is made of PA66 plastic with fiberglass reinforcement, as well as a black painted metal plate. The rotor is painted black and rotates clockwise when viewed towards the rotor. The fan impeller is mounted on a 133 mm unit with a 55 motor size. Regular inspection of the fan impeller for wear, deposits, and corrosion is recommended at least every six months. |
