Helios Fans SVS EC 315 A

The Helios SVS EC 315 A is a high-efficiency EC centrifugal in-line duct fan designed for silent and effective ventilation in residential, commercial, and industrial ducted systems. Its compact, flat casing is built from durable galvanized sheet steel and acoustically insulated with 50 mm thick mineral wool to reduce operational noise.

Fitted with twin-seal rubber gaskets, the intake and exhaust spigots ensure a secure connection to standard ductwork. For maintenance convenience, the fan includes a swing-out motor and impeller assembly, enabling quick servicing without dismantling the duct system.

This model features a dynamically balanced centrifugal impeller with backward curved blades, constructed from galvanized sheet steel for enhanced durability and quiet operation.

The fan is driven by a speed-controlled, energy-saving EC external rotor motor, offering IP54 protection. It is maintenance-free, equipped with ball bearings, and radio interference-free. Integrated temperature monitoring safeguards both the motor and electronics.

Fan speed is adjustable via an internal potentiometer or can be controlled steplessly using an external potentiometer or the universal EUR-EC control system. The unit is equipped with a standard IP54 terminal box mounted on an extended cable for flexible and secure electrical connections.
