The Helios SVR EC 125 is a slim, high-efficiency EC centrifugal fan designed for direct integration into duct systems. Built with a flat, durable casing from galvanized sheet steel, it ensures long-lasting performance in residential, commercial, and industrial ventilation applications.
Equipped with spigots on both intake and exhaust, featuring twin-seal rubber gaskets, the SVR EC 125 fits seamlessly into standard ductwork. The fan includes a service-friendly swing-out motor and impeller unit for easy cleaning and maintenance access.
The high-efficiency centrifugal impeller features backward curved blades made from premium polymer materials. Dynamically balanced for smooth, low-noise performance, it supports silent airflow in any setting.
Powered by an electronically commutated (EC) external rotor motor, this model offers IP54 protection, high energy efficiency, and maintenance-free operation. The motor is equipped with integrated electronic temperature monitoring for added reliability.
Fan speed can be adjusted steplessly via a built-in internal potentiometer or controlled externally using a potentiometer or the Helios EUR-EC control system. The fan connects through a standard IP54 terminal box mounted on an extended cable, allowing for fast and secure installation.
