Quest Exhaust Duct Kit for Quest 746 480V, 876 and 706, 50-HZ

Exhaust Duct Kit for Quest 746, 876, and 706 Dehumidifiers

Large commercial dehumidifiers generate a substantial volume of exhaust air, and directing that air away from the growing space, rather than releasing it into the same room, helps keep conditions consistent. This exhaust duct kit attaches to the existing duct collar across three related Quest models, letting you route exhaust to a separate room or an out-of-sight location.

It covers the Quest 746 480V (PN 4037610), Quest 876 (PN 4037600), and Quest 706 50-Hz (PN 4041800) dehumidifiers, giving one kit coverage across this model group.

• Covers Three Quest Models — fits the 746 480V, 876, and 706 50-Hz units.

Who Should Use This Quest Exhaust Duct Kit

Frequently Asked Questions

Which models does this kit fit?

It fits the Quest 746 480V (PN 4037610), Quest 876 (PN 4037600), and Quest 706 50-Hz (PN 4041800) dehumidifiers. That covers three related models in Quest's larger commercial lineup.

What does this kit do?

It routes exhaust air to a different room or an out-of-sight space instead of releasing it directly where the dehumidifier sits. That helps keep exhaust away from the growing area in larger facilities.

How is it installed?

It connects at the factory duct collar already on the unit, so the dehumidifier itself needs no modification. Installation follows the same process across all three compatible models.

Does this kit include intake fittings?

No, this kit handles exhaust air only. A separate intake duct kit is available for this model group if you also need to route intake air.
