Dank, damp air causes damaging mold, mildew and corrosion on houseboats. Instead of unsightly dehumidifying bags and fan units requiring drainage, Air-Dryr by Davis Instruments uses heat and natural convection to warm and dry the air, preventing mold and corrosion.

Designed for constant use, the compact Air-Dryr fits out of the way in an enclosed space and plugs into 110/220V power. It dries damp air by heating it above dew point, then releasing warmed air through top vents.

With no switch, fan or thermostat, the silent Air-Dryr is trouble-free and draws no more energy than a light bulb. A thermal cut-off shuts down the unit should air flow be impeded. Air-Dryr has no components to cause sparking, so it's safe for marine use in cabins, v-berths and engine rooms. For fresh-smelling air, to prevent condensation and protect woodwork, Air-Dryr is great for onboard compartments.

Made of durable polycarbonate, the Air-Dryr 500 from Davis Instruments handles up to 500 cubic feet, draws only 0.6 amps, 70W and measures 14 inches long by 5 inches wide. The Air-Dryr 1000 handles 1,000 cubic feet, draws 1.1 amps, 130W and measures 13.5 inches in diameter and 4.25 inches high.

Compared to standard dehumidifiers that can retail for $200 or more, the Air-Dryr 500 costs only $59.99 and the 1000, $69.99.
