The all-welded metal casing with rolled flanges helps achieve outstanding rigidity and minimum clearances between the casing and
the blades. There is an inspection hatch in the casing for easy maintenance. All the casing components are powder coated for improved
protection against the environmental effects.
The fan impeller has a split design and is connected to the motors.
The fan is driven by a three-phase asynchronous single-speed or double-speed motor with a square-cage rotor installed inside the casing.
