Helios Fans SVR EC 315 B

The Helios SVR EC 315 B is a high-efficiency EC centrifugal duct fan engineered for direct installation in space-limited ducted ventilation systems in residential, commercial, and industrial applications.

Its flat and durable casing is made from galvanised sheet steel, designed for long-lasting performance. The intake and exhaust connections feature twin-seal rubber gaskets, ensuring airtight integration with standard ducting. Maintenance is simple with a swing-out motor and impeller unit for easy internal access.

This model includes a dynamically balanced centrifugal impeller with backward curved blades, crafted from high-quality polymer for optimal airflow and reduced noise emissions.

The fan is driven by an energy-efficient, speed-controllable EC external rotor motor with IP54 protection. The motor is maintenance-free, radio interference-free, and includes ball bearings and integrated electronic temperature monitoring to enhance reliability and safety.

Fan speed can be fine-tuned using the built-in potentiometer or adjusted externally with a potentiometer or Helios EUR-EC universal controller. Electrical connection is made through a standard IP54-rated terminal box mounted on an extended cable for installation convenience.
