Quest Supply Duct Kit for Quest Dual 105, 155, 165, 205, 225, and 185 COOL

Supply Duct Kit for Quest Dual 105 Through 225 Dehumidifiers

Venting a dehumidifier's supply air directly into the room it sits in isn't always practical, especially in a multi-room facility where conditioned air needs to reach a different space. This supply duct kit attaches to the existing duct collar on the Quest Dual 105, 155, 165, 205, and 225 dehumidifiers, letting you route that air to a separate room or an out-of-sight location instead.

It also fits the Quest 185 Cool and 155 50-Hz variants, so one kit covers the full Dual model range plus these two related units.

• Covers Seven Quest Models — fits the Dual 105-225 range plus 185 Cool and 155 50-Hz.

Frequently Asked Questions

Which models does this kit fit?

It fits the Quest Dual 105, 155, 165, 205, and 225 dehumidifiers, along with the Quest 185 Cool and 155 50-Hz units. That covers the full Dual model range plus two related variants.

What does this kit do?

It lets you route the unit's supply air to a different room or an out-of-sight space instead of venting directly where the dehumidifier sits. That flexibility helps in facilities where conditioned air needs to reach an adjoining area.

How does it attach to the dehumidifier?

It connects to the duct collar already built into the unit, so no modification to the dehumidifier itself is required. Installation follows the same straightforward process across all compatible models.

Do I need a separate kit for return air?

Yes, this kit handles supply air only. A matching return duct kit is available separately for routing return air from another room.
