BFS 400X400 B1

Boxfan BFS

Duct fan with square connections.●

High capacity and very good efficiency.●

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 electric speed controller can be connected.●

Fan 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.●

Easy installation in any position.●

To comply with the ErP 2018 regulation, a local demand controller must be used.●
