Air-Dryr from Davis Instruments uses heat and natural convection to keep the air dry and prevent mold. Areas such as basements, closets, storage units, wine cellars, musical instrument rooms, vaults, pools, and spas are among the smaller spaces subject to mold and mildew, and the compact Air-Dryr is an alternative to dehumidifying bags or fan units with tanks to empty.
This unit is placed on the floor and plugged into a 110/120V outlet. The air is heated above dew point to hold the moisture in suspension so it will not settle on surfaces; then it is released through the top vents of Air-Dryr. As warmed air rises, cooler damp air is drawn into the unit, where it too is heated.
Designed to be left on 24 hours a day, Air-Dryr can handle a high volume of air. The neutral beige housing is made of strong and durable polycarbonate, and an aluminum base panel supports the tubular metal heating element. The units are silent, with no switch, fan, or thermostat. A thermal cut-off turns the unit off if air flow be impeded.
