CK 150 B1 aut tc

Product marked with this symbol has an AC motor. An induction motor is an electric motor were the rotor speed is asynchronous with the input voltage frequency.

This product is compliant with the Lot 6 directive (1253/2014) and approved for use in the EU and EFTA, also after 2018.

Duct fan with circular connections.
Proven performance and reliability.
Compact with high capacity and efficiency.
Low sound levels.
Operational in both 50 and 60 Hz.
Impeller with backward curved blades.
The external rotor motor has maintenance-free sealed ball-bearings and is very energy efficient.
For speed control a transformer or electronic speed controller can be connected.
Integrated motor protection.
Junction box has enclosure class IP 54.
Fan housing is manufactured from galvanized sheet steel.
The fan is intended to be installed in a duct system.
A duct connected fan can be installed outside or in damp environments.
Easy installation in any position.
To comply with the ErP 2018 regulation, a local demand controller must be used.
