The Gold Series AU-DC 12,000 BTU/h 230 V/50-60 Hz/1-Ph air handler, recipient of an Honorable Mention at the 2012 International Boatbuilders Exhibition and Conference (IBEX), incorporates many innovative features, including an optional Breathe Easy™ air purifier and rust-free composite drain pan. This AU-DC model features ultra-quiet, yet powerful, "WhisperCool" DC blowers. The corrosion-resistant composite drain pan quickly removes condensate water. Each drain hole is reinforced and has an external stop to prevent over tightening of the screw-in hose barb. Straight or 90-degree hose barbs may be used to better accommodate a variety of installation situations. Vibration-isolation mounting hardware can be attached at a variety of locations along the perimeter of the drain pan to ensure a quiter operation. The rotatable blower ring can be positioned easily by adjusting a single screw, and can even blow directly downward. The blower inlet adapter is made of a high-temperature resin to easily withstand the heat generated by the optional internal electric heating element. The manual heater-overload safety switch is easily accessible without disassembling the unit. The optional integrated Breathe Easy air purifier is positioned directly in the airstream. Our award-winning Breathe Easy technology eliminates odors and up to 99.9 % of contaminants. An upgraded Gold series EU package is available.
