Helios Fans SVS EC 200 A

The Helios SVS EC 200 A is a robust EC centrifugal in-line fan designed for quiet and efficient ventilation in residential, commercial, and industrial duct systems. Its casing is crafted from durable galvanised sheet steel in an extended flat format, acoustically insulated with over 50 mm of abrasion-resistant mineral fibreboard for superior noise reduction.

The fan features standard-sized intake and exhaust spigots with twin-seal rubber gaskets, ensuring tight, secure connections to ductwork. The motor and impeller unit can swing out for convenient cleaning and maintenance access.

Its centrifugal impeller is made from high-grade polymer and features backward curved blades, providing optimal airflow with low sound emission. The dynamically balanced construction guarantees smooth, vibration-free operation.

Powering the unit is a high-efficiency, speed-controllable EC external rotor motor rated to IP54. It is maintenance-free, ball bearing mounted, and equipped with integrated electronic temperature monitoring for added protection. Radio interference-free operation ensures reliable performance in sensitive environments.

Fan speed is adjustable via a built-in internal potentiometer or steplessly using an external potentiometer or the Helios EUR-EC universal control system. A standard IP54 terminal box with an extended cable enables straightforward electrical connection.
