Exhaust fan VEGA WGB125H - Hygrostat

Automatic humidity control and quiet operation in the bathroom

The VEGA WGB125H fan is designed for effective air exchange in rooms with increased humidity, such as bathrooms, toilets, or laundries. Its key advantage is a built-in hygrostat that automatically detects an increase in water vapor levels in the air and activates ventilation without the need for manual intervention. This means the user does not have to remember to turn on the device after bathing – the system operates independently, responding to the actual needs of the room. When humidity drops below the set threshold (adjustable between 60% and 90%), the fan does not switch off immediately but continues to operate for an additional time set on the timer potentiometer (from 3 to 30 minutes). This solution guarantees the complete removal of excess moisture and prevents the growth of mold or fungi.

The device features high performance with a low noise level. With an airflow of 180 m³/h and a power consumption of only 15 W, it ensures effective ventilation even in larger bathrooms without generating annoying noise (sound level is approximately 39 dB). This efficiency is made possible by the use of a modern motor with durable ball bearings, tested for 30,000 hours of continuous operation. As a result, the fan is not only energy-efficient but also reliable over many years of operation, which is important for both installers seeking durable solutions and users valuing tranquility.

Flexible installation and resistance to environmental conditions

The VEGA model construction allows for free installation on both walls and ceilings, facilitating adaptation to the specific ventilation layout of a given building. The casing is made of durable ABS plastic, which is resistant to UV radiation and corrosion caused by moisture. The classic white color and compact external dimensions (172 x 172 mm) ensure the fan aesthetically fits into most interiors, and its installation does not require complex procedures – mounting screws are completely hidden under the casing. The connection diameter is 125 mm, making it compatible with most standard ventilation ducts in residential and public buildings.

User safety is ensured by protection class IPX4, which means resistance to water splashes from any direction – a key feature in wet zones. The fan can operate in ambient temperatures up to 40°C, and its maximum static pressure is approximately 46-50 Pa, allowing it to effectively overcome flow resistance in short ducts or when using a check valve (available as an accessory). The device is powered by 230 V and is grounded, meeting strict safety standards for electrical equipment used in bathrooms.

Thanks to the combination of automatic humidity control with the possibility of manual activation (e.g., via a light switch), this model offers universal application. The hygrostat system has priority over manual control – if humidity rises above the set threshold during manual operation or after its completion, the fan automatically completes the cycle of removing water vapor. This intelligent approach eliminates the risk of leaving a closed room with excess moisture after a shower or cooking. In practice, this means the smooth cooperation of all elements: a 15 W motor drives an impeller achieving an efficiency of 180 m³/h with a quiet noise level of approx. 39 dB(A), while the whole unit is protected against splashes thanks to IPX4 class. Durability is provided by steel ball bearings adapted for continuous operation, while the hygrostat reacts precisely within a humidity range of 60% to 90%, and the timer allows adjusting the switch-off delay time to individual needs (range from 3 to 30 minutes). The entire unit is made of UV-resistant ABS plastic in white and can operate stably even at ambient temperatures reaching up to 40°C.
