Quest 70 Dehumidifier Duct Kit (4038599)

Send the Quest 70's dry air exactly where it's needed

The Quest 70 Dehumidifier Duct Kit lets you attach ducting directly to the Quest 70 Overhead Dehumidifier, so you can direct intake and exhaust airflow to specific parts of a sealed grow room rather than relying on the unit's natural draw. In a sealed space that targeted air distribution is what stops one corner running too humid while another stays dry, the kind of uneven moisture that drives mould, weak development and patchy flowering across the canopy. Fitted with 8-inch duct collars, the kit makes those supply and return connections quick and secure.

Key Benefits

• Purpose-built for the Quest 70 Overhead Dehumidifier
• 8-inch duct collars included for quick, secure supply and return connections
• Directs supply and return airflow to the areas that need moisture removal most
• Evens out humidity across sealed grow rooms, tents and hydroponic setups
• Improves air circulation for steadier conditions through veg and bloom

How to Use

1. Turn off and unplug the Quest 70 before installation.

3. Secure compatible 8-inch ducting to the collars with clamps or fasteners.
