Davis Air Dryer 1000

The Air-Dryr 1000 is the same idea as the 500, sized for twice the space. It handles up to 1,000 cubic feet, so it suits a bigger storage unit, a basement room, a large boat cabin or an RV.

It warms damp air just enough to keep the moisture suspended (above dew point) and lets it rise out the top vents while cooler air is drawn in below. There’s no fan, switch or thermostat. It runs silently around the clock.

• Up to 1,000 cubic feet.
• Draws 1.1 amps, 130 watts.
• Round unit, 13.5″ across and 4.25″ high.
• Plugs into a 110/120V outlet and stays on 24 hours a day.
• Thermal cutoff if airflow is blocked. Safe to the touch, no sparking parts, UL listed, safe for marine use.

500 or 1000? Work out the cubic feet (length x width x height). Up to 500, the smaller rectangular Air-Dryr 500 is enough and draws 70 watts. Over that, up to 1,000, get this one.

Like any plug-in unit, it’s for an enclosed room with an outlet: a garage, storage unit, basement or cabin. Don’t put it inside a fabric shelter or under a cover. For a bike stored in a shelter, use a no-power moisture absorber instead. More in our motorcycle storage guide.

Common Questions

Air-Dryr 500 vs 1000: which one do I need?
Go by the space. The 1000 handles up to 1,000 cubic feet and draws 1.1 amps, 130 watts. The 500 covers half that. The 1000 is round, 13.5 inches across and 4.25 inches high.

Is it safe to leave an Air-Dryr on all the time?
It’s designed to run 24 hours a day. It’s UL listed, safe to the touch, has no sparking components, and a thermal cutoff turns it off if airflow gets blocked.

How much does an Air-Dryr cost to run?
Davis says it costs no more to run than a light bulb. The 1000 draws 130 watts. Keep it in a garage, basement or storage unit, never inside a fabric shelter or under a cover.
