Circulating wheel
The impeller is radial with backward curved blades, made of galvanized steel sheet. It is statically and dynamically balanced.
Motor
is asynchronous with short armature. The motors have Class F insulation and an operating temperature of -40 to +120˚C. Sealed ball bearings with grease packing for life. IP55 protection.
Square box

Instructions
The fans are suitable for more demanding applications (professional kitchens, industry) due to their higher operating temperature (120 °C) and performance characteristics. If the fan is operated in heat and smoke extraction mode, speed control is not permitted and safety protections such as thermocontacts must be disabled.
Caution
Fans are supplied without flanges, motor cover, frame and silent blocks fitted. These elements must be ordered separately (see accessories).
