Compact radial fan for water damage, building drying, and professional drying
The WDH-C20 Mini Turbo Fan is a compact and powerful radial fan designed for targeted drying of hard-to-reach areas. With an air capacity of up to 420 m³/h, it is particularly suitable for water damage restoration, building drying, renovation work, and targeted ventilation of cavities and small areas.
In the event of water damage, moisture often remains in places that are difficult to reach with a standard fan. The WDH-C20 generates a concentrated airflow with high pressure, thereby supporting the targeted drying of areas behind furniture, under built-in fixtures, on floors, or in hard-to-reach cavities.
Thanks to its compact design, the Mini Turbo Fan can be used flexibly. The airflow can be precisely directed in various positions, making the device particularly well-suited for restoration projects and professional water damage drying.
After water damage, moisture must be removed from affected areas as quickly as possible. It is often insufficient to merely circulate the room air. Moisture can collect, for example, behind kitchen cabinets, under built-in units, under bathtubs, or in cavities.
The WDH-C20 radial fan creates a targeted airflow, thereby supporting the ventilation of such hard-to-reach areas. The air movement promotes the evaporation of moisture and, in combination with a dehumidifier, can significantly assist in the drying process.
Radial fans differ from simple axial fans in their ability to generate a directed airflow with higher pressure. This allows air to be guided more precisely into hard-to-reach areas.
The WDH-C20 Mini Turbo Fan is therefore especially suitable for situations where concentrated airflow is more important than large-scale air circulation.
The WDH-C20 can be positioned flexibly, allowing the airflow to be directed precisely at the area to be dried.
| Position | Use |
|---|---|
| Horizontal | Direct airflow for ventilating and drying surfaces. |
| Inclined | Targeted airflow for transitions and hard-to-reach areas. |
| Tilted | Optimized airflow into cavities and under built-in units. |
The compact Mini Turbo Fan can be used in numerous situations where targeted air movement is required.
| Application Area | Use Case |
|---|---|
| Water damage | Targeted support for drying after water damage in apartments and houses. |
| Kitchens and bathrooms | Ventilation and drying behind kitchen and bathroom furniture and under built-in units. |
| Building drying | Support for renovations and restoration work. |
| Floors and carpets | Targeted air movement to support the drying of floors and carpets. |
| Cavities | Airflow into hard-to-reach areas and enclosed zones. |
| Small rooms | Support for air circulation in smaller or confined areas. |
| Car interiors | Support in drying out damp vehicle interiors. |
After water damage, moisture can collect behind kitchen ranges, bathroom furniture, or other built-in units. Such areas are often poorly ventilated and therefore dry out slowly.
Due to its compact dimensions, the WDH-C20 Mini Turbo Fan can be positioned precisely near such areas. The directed airflow supports air circulation and thereby drying.
The combination with a dehumidifier is particularly effective. While the WDH-C20 moves the air in a targeted manner, the dehumidifier removes the released moisture from the room air.
In professional drying operations, flexible airflow management is crucial. Large fans are suitable for general air circulation, but their use is limited in narrow areas.
The WDH-C20 complements such drying systems through its compact design and directed airflow. This allows it to be used precisely where additional air exchange is needed.

The WDH-C20 Mini Turbo Fan is suitable for private users, tradespeople, restoration companies, and professional drying businesses that require a compact solution for targeted airflow.
The WDH-C20 is used for targeted airflow and drying during water damage, renovation, and restoration work. It is particularly practical for hard-to-reach areas such as behind kitchen furniture, under built-in units, or in cavities.
A radial fan generates a directed airflow with relatively high air pressure. This allows air to be guided precisely into hard-to-reach areas, which is especially helpful when drying cavities and areas behind built-in fixtures.
Yes. The combination of the WDH-C20 Turbo Fan and a dehumidifier is particularly useful for drying after water damage. The fan ensures targeted air movement, while the dehumidifier removes moisture from the room air.
Yes. The WDH-C20 is designed for long-term professional use in drying and restoration projects.
The compact turbo fan is suitable for smaller rooms as well as confined or hard-to-reach areas. This includes, for example, basements, bathrooms, kitchens, closets, containers, and damp vehicle interiors.
The WDH-C20 achieves a circulation volume of 420 m³/h. The blowing speed is approximately 8.5 m/s.
The WDH-C20 can be positioned in three different ways: horizontal, inclined, or tilted. This allows the airflow to be aimed precisely at different areas.
Yes. The WDH-C20 was developed, among other things, for targeted drying during water damage and restoration work. The directed airflow is particularly effective at supporting drying in hard-to-reach areas.
Yes. The compact design and directed airflow make the WDH-C20 an excellent choice for ventilation and drying support behind kitchen and bathroom furniture.
According to the technical specifications, the sound pressure level is approximately 56–58 dB(A).
