IRB 400 B3 ErP

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.

Insulated duct fan with circular connections.
Equipped with 50 mm of thermal and acoustic insulation makes it ideal for handling cold air.
Designed for high pressure and long, complicated duct runs.
The design prioritise functionality, durability and longevity.
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 can be connected.
The 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.
