Quest 155 Dehumidifier - Supply Duct Out Kit (4028607)

The Quest 155 Supply Duct Out Kit is designed to allow ducting to be connected to the outlet side of the Quest Dual 155 dehumidifier. This enables growers to direct the warm, dry air produced by the unit away from the grow room and into another space or ventilation path. In indoor growing environments, managing both humidity and heat is essential for stable climate conditions, especially during the flowering and bloom stage when humidity levels and airflow directly impact plant health and bud density.

By allowing the dehumidifier’s output air to be ducted away, this kit helps growers maintain a more controlled grow room environment while improving airflow management in hydroponic systems, soil or coco setups.

Key Benefits

• Allows ducting to be connected to the outlet side of the Quest Dual 155

• Helps redirect warm, dry air away from the grow room

• Supports stable humidity and temperature control in indoor growing environments

• Improves airflow management in grow tents and large grow rooms

• Includes two 10-inch duct collars for flexible duct connections

• Foam sealing components help ensure an airtight fit to the unit

• Includes self-drilling screws for straightforward installation

How It Solves Grow Problems

High-capacity dehumidifiers remove large amounts of moisture from the air, but they also release warm, dry air back into the space. In tightly controlled indoor growing environments, this extra heat can raise temperatures and make climate management more difficult.

The Quest 155 Supply Duct Out Kit allows growers to duct that air away from the grow room, helping maintain stable temperatures while still controlling humidity levels. This creates a more balanced environment for vegetative growth and flowering, reducing stress on plants and helping growers maintain strong plant health and consistent yields.

How to Use

1. Turn off and unplug the Quest Dual 155 dehumidifier before installation.

2. Position the supplied 10-inch duct collars on the outlet side of the unit.

3. Use the included self-drilling hex screws to secure the collars to the unit.

4. Apply the supplied foam seals to ensure an airtight connection between the collar and the dehumidifier.

5. Attach compatible ducting to the collars and route it to the desired exhaust location.

6. Ensure all duct connections are properly secured and sealed to prevent air leaks.

Note: Ducting and register grills are not included and must be installed separately if required for your grow room ventilation setup.
