Archived product

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.

Low profile duct fan with circular connections.
A small and useful duct fan which are perfect for spaces with minimum height clearance.
With one connection on the inlet side.
High capacity and efficiency with 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.
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.
Duct connections are equipped with rubber seals.
The fan is intended to be installed in a duct system.
A duct connected fan can be installed outside or in damp environments.
The mounting brackets simplify installation in any position.
To comply with the ErP 2018 regulation, a local demand controller must be used.
