IRB 600x350 A1 EC-y1

Insulated duct fan.
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 backward curved blades.
The external rotor motor has maintenance-free sealed ball-bearings and is very energy efficient.
Speed controlling can be done with the built-in potentiometer, 0-10 V alt. external control.
Integrated motor protection.
Junction box has enclosure class IP 54.
The housing is manufactured from galvanized sheet steel.
The fan is intended to be installed in a duct system.
A duct connected fan can be installed outside or in damp environments.
