Quest Supply Duct Kit - Quest Dual 110 and 150

Supply Duct Kit for Quest Dual 110 and 150 Dehumidifiers

A Quest Supply Duct Kit connects a compatible dehumidifier's supply air outlet to rigid or flexible ductwork, so dehumidified air gets delivered to a specific point in the room rather than discharging directly at the unit. The kit includes the supply air flange, collar, and the hardware needed to make an airtight connection between the unit and your ducting.

This kit is sized for the Quest Dual 110 and Dual 150 models, letting installers duct supply air from either unit to a specific point in the grow room.

Key Features & Benefits

• Supply air flange — the flange is sized to mate directly with the compatible dehumidifier's supply outlet, giving a proper seal point for connecting ductwork.
• Matching duct collar — the collar accepts standard round ducting, letting installers route dehumidified air to a specific point in the grow space instead of discharging it at the unit.
• Complete mounting hardware — fasteners and gasketing are included, so the kit doesn't require separately sourcing hardware to complete the connection.
• Supports controlled-environment airflow design — directing supply air through ductwork helps even out humidity control across a room rather than concentrating dry air near the unit.
• Model-specific fit — the flange and collar dimensions are matched to the compatible unit series, so the kit installs without field-modifying the sheet metal.

Who Should Use This

This kit is for growers and facility installers routing a compatible Quest dehumidifier's supply air through ductwork to a specific location in the room, rather than relying on the unit's direct discharge pattern alone.

About Quest

Quest is a Therma-Stor brand. It focuses on commercial dehumidification. Therma-Stor is headquartered in Madison, Wisconsin. It's the same parent company behind the Anden brand. Therma-Stor has built dehumidifiers and environmental-control equipment for decades. Quest specifically targets commercial and industrial moisture control. Think indoor cultivation, food production, and commercial buildings. That's a different focus than residential basement units. Many overhead models use the company's patented M-CoRR design. M-CoRR stands for multi-coil refrigeration. The design recycles heat pulled from the air. That happens during dehumidification itself. It improves energy efficiency as a result. It also cuts heat sent back into the room.

Frequently Asked Questions

What's included in the Supply Duct Kit?

The kit includes the supply air flange, a matching duct collar, and the hardware needed to complete an airtight connection to the dehumidifier's supply outlet. No separate hardware purchase should be necessary for a standard installation.

When would I skip this kit entirely?

If the dehumidifier is set to discharge air directly into the room without ductwork, this kit isn't necessary. It's specifically for installations that need to route supply air to a different point in the space through ducting.

Which Quest models is this Supply Duct Kit compatible with?

This kit is compatible with the Quest Dual 110 and Dual 150 models. Confirm your exact model and voltage variant against the current compatibility list before ordering, since supply flange dimensions vary across Quest's model lines.

Does this kit include the ductwork itself?

No, the kit provides the flange, collar, and connecting hardware at the unit end. Rigid or flexible ductwork, along with any additional fittings needed to reach the discharge point, is sourced separately based on the specific installation layout.
