IRB 400 A1 EC
IRB EC Circular
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 priorities 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.●
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.●
