Quest 155 Dehumidifier - Return Duct Kit (4028610)

Site Your Quest 155 Outside the Grow Room Without Losing Capacity

The Quest 155 Return Duct Kit is a purpose-built ducting accessory for the Quest Dual 155 dehumidifier. It lets you connect return ducting to the unit so the dehumidifier can be installed remotely - outside the grow room or tent - while still pulling humid air from the cultivation space. That is the answer for growers who need serious dehumidification but do not want a large unit taking up floor space, adding heat or adding fan noise inside the canopy. The result is precise humidity control through veg and flower with a tidier, more efficient grow environment.

Key Benefits

• Remote installation - site the Quest Dual 155 outside the grow room while it draws air from inside
• Less heat and noise in the growing space, keeping climate control easier
• More usable floor space inside the tent or grow room
• Heavy-duty 12-inch flange designed specifically for the Quest 155 / Dual 155
• Better airflow management in large grow rooms and sealed, climate-controlled setups
• Stable humidity control for strong plant health and improved yields

Large Dehumidifier Crowding and Heating Your Grow Space?

Big dehumidifiers eat valuable space inside a grow tent or grow room and the heat they generate works against your climate control - exactly when you need stable humidity most, particularly through the bloom stage where excess moisture raises the risk of mould and poor bud density. Running a return duct out to a remotely sited unit keeps full dehumidification capacity without the clutter.

How to Use

1. Turn off and disconnect the Quest Dual 155 before fitting the kit
2. Attach the 12-inch return flange to the designated return air opening on the unit
3. Secure the flange firmly using appropriate fixings
4. Connect compatible 12-inch ducting to the flange
5. Route the ducting from the grow room to the remotely placed dehumidifier
6. Seal all duct joints properly to stop air leaks and maintain suction
