Gold Series air handlers, recipient of an Honorable Mention at the 2012 International Boatbuilders Exhibition and Conference (IBEX), incorporate many innovative features, including an optional Breathe Easy™ air purifier and rust-free composite drain pan. AU-DC models feature ultra-quiet "WhisperCool" DC blowers that are strong enough to overcome high-static-pressure duct. The 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.
