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.
Impeller with forward 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.
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.
