Helios Fans ELS-VF 60/35

The Helios ELS-VF 60/35 is a quiet and efficient ultraSilence fan unit designed for bathroom ventilation with two-speed airflow settings of 60 m³/​h for general ventilation and 35 m³/​h for trickle ventilation. Equipped with an advanced electronic dynamic humidity sensor, it automatically increases fan speed to high when the set humidity level is exceeded and returns to low speed once humidity normalizes.

Its spiral housing contains an aerodynamically and acoustically optimized radial impeller, offering a high pressure reserve and low noise output that complies with DIN 4109 T.2 noise control standards. Installation is user-friendly, featuring tool-free fan insertion and an integrated quick plug connector for easy electrical connection.

The energy-efficient motor is enclosed in a robust aluminum cast casing and runs on maintenance-free ball bearings rated for 40,000 operating hours. The fan consumes just 18 W on high speed and 9 W on low speed. Its elegant, flat, and award-winning white polymer fascia blends seamlessly with room interiors.

A class G2 permanent air filter, which is dishwasher-safe, is housed behind the hinged fascia. The built-in filter change indicator notifies when cleaning is necessary. Control options include manual On/​Off switching on high speed, an overrun timer of approximately 6 minutes, and a delayed start of about 45 seconds. Manual control of both speeds is possible using the optional DSEL 2 switch. The automatic humidity control can be disabled with an additional switch, requiring a 5×1.5 mm² power supply cable.

The ELS-VF 60/35 is fully insulated (Class II) and rated IPX5 for hose-proof protection, making it suitable for installation in bathroom zone 1. Combining automatic humidity sensing, quiet operation, and energy efficiency, this fan unit provides reliable ventilation tailored to varying room conditions.
