Roof fan with square connection.
Vertical 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 which is polyester plastic coated in black as standard.
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.
The fan complies with environmental requirement M2.
