Helios Fans ELS EC 45÷25÷60 NC

The Helios ELS EC 45÷25÷60 NC is a fan insert designed for quiet and efficient ventilation featuring ultraSilence® technology. It offers three selectable airflow rates — 45, 25, and 60 m³/​h — to suit both demand-controlled and basic ventilation needs. The fan includes a codeable overrun, switch-on delay, and interval operation options for versatile control.

Constructed with a spiral casing and an aerodynamically and acoustically optimized radial impeller, this fan ensures a high-pressure reserve while maintaining a low noise level, compliant with sound insulation standards according to DIN 4109 T.2.

Installation is tool-free with a slide-in mechanism that simultaneously completes the electrical connection via a plug-in coupling. The energy-saving EC motor is housed in a durable closed cast aluminum casing and features maintenance-free ball bearings rated for 40,000 operating hours.

The fan’s flat, elegant alpine white façade has received multiple design awards and is made from high-quality plastic. It includes a permanent, dishwasher-safe air filter (class G2) located behind a hinged, closed front panel. An integrated filter contamination indicator provides a visual warning when cleaning is needed, ensuring easy maintenance and optimal performance.
