Where are electric micro-dehumidifiers used?

The 35mm barrel mounting includes both the RS model dehumidifier and VREG2 power supply within a single housing. It is fully assembled and includes a locking ring for ease of installation.You only need to add a standard 15W USB-C power supply.

Membrane Dehumidifier Mounting Kits

Rosahl membrane dehumidifiers are usually installed inside the enclosure or cabinet they’re protecting. But for smaller enclosures, mounting the dehumidifier externally can sometimes work better—giving you more space inside and easier access.

To make installation simple, we offer a range of mounting kits for both internal and external setups. These kits help position the membrane correctly so it can effectively remove moisture, no matter where it’s mounted. Three kits styles are available for internal and external mounting of different membranes.

Pre-Assembled Membrane Dehumidifier 

Streamline your setup with our CE/UKCA-certified Rosahl dehumidifiers—pre-assembled for fast, hassle-free installation.

Available in five sizes, they’re designed to protect enclosures up to 250 litres. For applications requiring relative humidity below 40%—such as drying 3D printer filament—it is essential to consult our selection guide to ensure optimal performance. Choosing the right model helps avoid underperformance and ensures consistent moisture control.
