LPKB 315 E1 EC-y2

Low profile duct fan with circular connections.
A small and useful duct fan which are perfect for spaces with minimum height clearance.
With one connection on the inlet side.
High capacity and efficiency with low sound levels.
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.
Fan 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.
The mounting brackets simplify installation in any position.
