TKH 760 F3 EC-y1 Galv

Roof fan with square connection.
Horizontal outlet.
High performance and proven reliability.
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 and is polyester plastic coated. Can be ordered uncoated or with coating that complies with the Environmental class M3/Corrosion class C4.
Swing-up design to simplify maintenance and cleaning of the impeller.
The easiest way to mount the roof fan is with a roof curb TFU.
