What sets the Helios fan apart
Helios has been a trusted name in ventilation solutions for decades. This fan combines sensitive humidity control with a quiet, long-lasting motor. Unlike simple models, it doesn't just react to a switch but continuously monitors the room air – preventing mold growth and protecting building fabric.
Ideal for...
The fan is especially suitable for windowless bathrooms, guest WCs, utility rooms, and any space where moisture needs to be quickly removed. It's also a practical, low-maintenance solution for rental apartments or holiday homes to maintain a healthy indoor climate.
How to use the Helios fan
After installation, connect the fan to the mains. The humidity control works fully automatically: when the relative humidity exceeds the set threshold, the fan starts and turns off again once levels drop. If desired, you can manually activate the second speed via a separate light switch (not included). Clean the grille and impeller occasionally with a damp cloth.
Helios is a German manufacturer of ventilation systems with decades of experience. The company offers a wide range of fans for residential and commercial applications – from simple extractors to complex heat recovery ventilation units.
A humidity-controlled fan turns on automatically when the relative humidity in the room exceeds a set level. The built-in sensor continuously measures humidity and activates the motor – extracting moist air without any manual action needed.
It is ideal for bathrooms, toilets, utility rooms, and any spaces with high humidity. The 98 mm cut-out opening fits standard ceiling or wall ducts. Direct extraction to the outside or an exhaust shaft is required.
The fan has a 98 mm cut-out opening, is two-speed (basic and boosted), weighs 0.78 kg, and features an integrated humidity sensor. The color is white. It comes with a 24-month manufacturer warranty.
The delivery includes the Helios fan with humidity control, mounting hardware, and an instruction manual. A separate switch for manual speed selection is not included.
Clean the grille and the fan impeller occasionally with a damp, lint-free cloth. Avoid harsh cleaning agents. For heavy soiling, the grille can be carefully removed. Always disconnect the fan from the power supply before cleaning.
