Extraction fan LOOP WL100H - Hygrostat

Automatic Humidity Management

The fan operates continuously on the first speed setting — no manual switching required. When room humidity exceeds 70%, it automatically switches to a higher speed to increase efficiency and remove water vapor more quickly. Once humidity drops below 70% — after a 15-minute delay — it returns to the low speed setting. No additional buttons are needed; however, if the installer connects it to a double wall switch, speeds can be manually selected. After manual switching is turned off, the unit automatically reverts to the low speed setting after 15 minutes. This hygrometer function is standard in the WL100H model.

Installation and Construction

It can be mounted either on the wall or on the ceiling. Thanks to its grounding and IPX4 rating, it is safe for use in humid environments. The connection diameter is 100 mm — compatible with standard ventilation ducts. The ABS housing is lightweight, moisture-resistant, and easy to install. The "click" type mount allows installation of panels from the System+ series — enabling integration with existing layouts without requiring full replacement.

Performance and Energy

Airflow on the second speed setting is 70 m³/h — the only value confirmed in the manufacturer's technical data. On the first speed setting, airflow is 42 m³/h (confirmed by online sources). Power consumption is 4 W on the first speed and 6 W on the second (according to multiple external sources). Noise level: 26 dB on the first speed, 32 dB on the second — values confirmed by several independent retailers. The device does not require a transformer; it is powered directly from a 230 V mains supply.

Safety and Limitations

IPX4 protection guards against water splashes — suitable for bathrooms, but not for installation above gas stoves, boilers, or open fireplaces. Maximum operating temperature is 40°C — do not install in areas with elevated temperatures. It does not include a non-return valve; if protection against backflow is required, it must be added separately (e.g., ZZ100).

Warranty and Usage

The manufacturer provides a 5-year warranty — confirming the quality of components and construction. Ball bearings ensure longer service life and quieter operation compared to standard solutions. The fan is designed for continuous operation — no breaks or special operating conditions are required.
