Drying inside walls, behind cabinets and inside other complex assemblies used to be almost impossible. The Dri-Eaz DriForce InterAir Drying System (F211) can save the time and money of demolishing and rebuilding after suffering flooding or other water damage. The InterAir system allows you to direct high-pressure air into hard-to-reach structures and dry them quickly and with minimal disruption. The system requires only making quarter-inch holes behind baseboards or kickplates to gain access these interior spaces. Attach the InterAir system to deliver warm dry air to these spaces for fast, effective drying.
