Helios Fans SVS EC 315 B

The Helios SVS EC 315 B is a premium EC in-line centrifugal duct fan featuring a sound-insulated, flat casing for quiet and efficient operation. Designed for integration into duct systems in residential, commercial, or industrial settings, it ensures reliable air movement with minimal noise.

The housing is constructed from durable galvanized sheet steel and internally lined with 50 mm thick mineral wool, providing excellent acoustic insulation. Both intake and exhaust ports come with twin-seal rubber gaskets for a secure fit with standard ducting. Maintenance is made simple thanks to the swing-out motor and impeller assembly, allowing easy cleaning without needing to dismantle the entire unit.

Its dynamically balanced centrifugal impeller with backward curved blades is crafted from galvanized sheet steel, ensuring smooth, quiet airflow and long-term performance.

Power is supplied by a high-efficiency, speed-controllable EC external rotor motor that is maintenance-free and radio interference-free, with integrated electronic temperature monitoring for added safety. An internal potentiometer allows precise fan speed adjustment, while external speed control is possible via a potentiometer or the Helios EUR-EC universal control system. The unit features an IP65-rated terminal box mounted externally on the casing for secure and straightforward electrical connection.
