Perfect for maintaining comfort and air quality inside your trailer when you travel to areas with high humidity, the Airstream Ultimate 4000 Dehumidifier for Travel Trailers is a powerhouse dehumidifier that's small enough to stow away inside your Airstream when you're not using it. Not only does it work to improve interior air quality and comfort when used regularly, but it also provide excellent drying capabilities for wet towels and bathing suits when laundry facilities are hard to come by.
The first RV dehumidifier to use innovative rotary desiccant technology to provide high volume dehumidification without requiring a compressor, the Airstream Ultimate 4000 Dehumidifier is designed for low maintenance operation. It features a high-capacity water catch basin and the option for attaching a self draining hose (hose not included). The Airstream Ultimate 4000 Dehumidifier also includes a built-in ionizer that helps freshen interior air.
Use the Airstream Ultimate 4000 Dehumidifier in the main cabin of your Airstream travel trailer, or set it up inside your trailer's shower to create an excellent "drying room" for wet towels, bathing suits, and gear. A built-in "Dryer Mode" and electronic louvers help direct warm, dry air at wet gear, and a convenient timer provides versatility.
