Davis Air Dryer 500

Damp storage spaces breed mildew and rust. The Davis Air-Dryr 500 keeps the air above its dew point so moisture stays in the air instead of settling on what you’ve stored. Set it on the floor, plug it in, and leave it on 24 hours a day.

How it works: it gently warms the damp air, the warm air rises out the top vents, and cooler damp air gets pulled in underneath to take its place. No fan, no switch, no thermostat. Just convection, so it’s silent.

• Handles up to 500 cubic feet.
• Draws 0.6 amps, 70 watts. Davis says it costs about as much to run as a light bulb.
• 14 x 5 x 4.5 in rectangular unit that fits in tight spots.
• Thermal cutoff shuts it off if airflow gets blocked.
• Safe to the touch, no sparking components, UL listed, safe for marine use.

Davis lists closets, basements, storage units, gun cabinets, RVs, trailers and boat cabins, bilges and V-berths among its uses.

One limit: it needs an outlet and an enclosed space. Use it in a garage corner, storage unit or cabin, not inside a fabric shelter or under a cover. For a bike in a shelter, a no-power moisture absorber is the better fit. Bigger room? See the Air-Dryr 1000.

Common Questions

How does the Davis Air-Dryr work without a fan?
It warms the air just above dew point so moisture stays suspended instead of settling. Warm air rises out the top vents and cooler damp air gets drawn in. Natural convection does the work, silently.

How much space does the Air-Dryr 500 cover?
Up to 500 cubic feet. It’s a 14 x 5 x 4.5-inch rectangle that draws 0.6 amps, 70 watts. For a bigger room, look at the Air-Dryr 1000.

Can I put an Air-Dryr inside my motorcycle shelter?
No. Don’t run it inside a fabric shelter or under a cover. Use it in a garage, shed or storage unit with a 110/120V outlet. Inside a shelter, use a no-power No Damp absorber.
