Mold, mildew, cold drafts and corrosion are a fact of life in RVs and
other outdoor-related environments. Instead of messy dehumidifying bags
or fan units with tanks to empty, Air-Dryr from Davis Instruments uses
heat and natural convection to keep the air dry and prevent mold. The
compact unit is placed on the floor and plugged into a 120V outlet. The
air is heated above dew point to hold the moisture in suspension so it
won’t settle on surfaces, then 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 handles a high volume of
air. The attractive, neutral beige housing is made of strong and
durable polycarbonate. Slim and stable, it can be placed out of the way.
Silent and costing no more to operate than a light bulb, the
unit is trouble-free, with no switch, fan or thermostat. A thermal
cut-off turns the unit off should air flow be impeded. With no
components to cause sparking, Air-Dryr is also safe for marine use. An
alternative to expensive dehumidifiers, the Air-Dryr 500 from Davis
Instruments handles up to 500 cubic ft., draws only 0.6 amps, 130W,
measures 14″ L x 5″ W x 4.5″ H and retails for $57.99. The Air-Dryr 1000
handles up to 1,000 cubic ft., draws 1.1 amps, 130W, measures 13.5″ in
diameter and 4.25″ high and costs $67.99.
