Commercial & Bulk Purchasing

Who This Is For
- You are ducting a high-capacity Quest unit because generic kits never seal correctly and let humid air leak back in.
- You are setting up remote ventilation because your floor plan requires the unit to sit far from the primary exit point.
What We Found
- The 22 included screws ensure a completely airtight seal that does not rattle even under high static pressure.
- We prefer this rigid plate over generic collars because it actually holds its shape when the ducting is full of air.
What Users Say
- Facilities that swapped to this kit say their ambient temperatures dropped once they piped the heat outside.
- Operators report that the 12 inch collar fits standard insulated ducting without needing extra transition pieces.

No, this kit is designed specifically for the exhaust outlet. For intake ducting on compatible models, you would need the Quest Intake Duct Kit.
Ducting allows you to precisely control your environment. You can exhaust the warm, dry air into a specific area that needs it, or vent it out of the room entirely to manage temperature. This is crucial for creating the perfect conditions in a grow room. For more information, read our guide on how to lower humidity in your grow room.
