UNIT DESIGN AND OPERATING PRINCIPLE

Fan with a casing modi cation without terminal box
* Not included in the delivery set, available as a special accessory.
The all-welded metal casing with rolled flanges results in outstanding rigidity and minimum clearances between the casing and the
blades. There is an access door 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 motor with a square-cage rotor installed inside the casing.
The fan casing modifications depend on the electrical cable connection options:
• The cable is connected to the electric motor terminal box via a cable gland in the casing for the modification without a terminal box.
• The cable is connected to the terminal box on the casing for the modification with a terminal box.
