Centrifugal duct fan CFk 315 VIM SHUFT NS-1077773

The detachable housing of CFk VIM series fans is made of a composite material with enhanced sound-absorbing and impact-resistant properties. The fans are equipped with SHUFT motor-impellers with plastic or metal backward-curved blades. The motor is an asynchronous type with an external rotor IP44, and the terminal box is IP55. The electric motor with the impeller is statically and dynamically balanced in 2 planes. The motor ball bearings are maintenance-free and have a long service life. The fan motor features built-in thermal protection with automatic restart. Fan speed regulation is achieved by varying the voltage using TRE-T five-step transformers or SRE single-phase smooth speed controllers. Multiple fans can be connected to one controller, provided that the total current of the fans does not exceed the rated current of the controller. Used for air movement in round ducts of supply and exhaust ventilation systems for residential, public, administrative, and industrial purposes.
