The FEF series is a range medium performance fans featuring external rotor motors and sickle blade impellers for very quiet operation. Compact case design allows installation in tight spaces. Ideal for medium to low flow and pressure ducted systems. Fans can be mounted at any angle.

Construction
Cases are of galvanised or powder coated sheet steel with roll formed flanges. Motor supports are of corrosion protected steel.

Motors
Motor windings incorporate class ‘B’ or ‘F’ insulation as standard. Motor bearings are sealed for life and maintenance free. Integral thermal overload protection is generally not provided and is the responsibility of the installing electrical contractor. Failure to provide thermal overload protection voids the warranty.

Testing
Rated fan performance has been determined by testing to ISO 5801 : 2007. Fan sound data has been determined by testing to ISO 13347 : 2004.
