Duct fan for ventilation SVF 50-30/25-4E, SVF Series, rotary motor, built-in thermal contacts, step-type regulators RTTT, RTTO, in the rectangular duct of the ventilation system protect from overheating.

Application
Adjustable radial duct fans with forward curved blades, type SVF, are used in ventilation and air conditioning systems. Fans are designed to move air and other non-explosive gas mixtures. The fans are used for direct installation in rectangular ducts of air conditioning and ventilation systems, industrial and public buildings. For indoor and outdoor use, to move air free of hard, fibrous and abrasive materials in temperate climates.

Applicable electric motors The winding is equipped with additional moisture protection. As a standard, electric motors are protected by a thermal contact located inside the motor winding. When the motor windings overheat, in the event of overload, phase loss, high air temperature, etc., the thermal contact opens the protection circuit of the protective relay. Protection of the electric motor using thermal contact is the most reliable and accurate, unlike other types of protection.
