KVFU 250 A aut tc

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

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.

Wall fan with circular inlet connection.
KV has a square mounting plate.
Proven performance and reliability.
Compact with high capacity and efficiency.
Suitable for a wide variety of applications.
Operational in both 50 and 60 Hz.
Impeller with backward curved blades.
The external rotor motor has maintenance-free sealed ball-bearings.
Integrated motor protection.
Junction box has enclosure class IP 54.
For speed control a transformer or electronic speed controller can be connected.
Fan housing is manufactured from galvanized sheet steel.
The fan is intended to be installed in a duct system, mounted on the inside wall.
Easy installation in any position.
Can be used in damp environments.
To comply with the ErP 2018 regulation, a local demand controller must be used.
