Motorized impellers for duct fans with the circular section
Motorized impellers with backward-curved blades are used in the manufacture of duct fans with the circular section.
Motorized impellers are highly reliable, durable and energy efficient, and they are in no way inferior to well-known European brands.
Design options:
All motorized impellers are equipped with thermal contacts with automatic restart.
Windings are powered by the thermal contacts.
If the motor overheats, the fan will turn off and restart automatically when it cools down. Control is enabled both with transformer type regulators for voltage changes and phase regulators.
