TKS 400 B Brick red w cable

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.

Roof fan with square connection.
Horizontal outlet.
High performance and proven reliability.
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 which is polyester plastic coated in black as standard.
Swing-up design to simplify maintenance and cleaning of the impeller.
The easiest way to mount the roof fan is with a roof curb, TFU to TKS.
The fan complies with environmental requirement M2.
To comply with the ErP 2018 regulation, a local demand controller must be used.
