Who This Is For
- You are upgrading your ventilation because flimsy single-ply ducting keeps tearing every time you adjust your fan.
- You are rerouting your airflow because rigid piping makes it impossible to navigate around tight corners.
What We Found
- This material is much stiffer than cheap dryer vent stuff, which makes it way easier to pull tight and secure.
- We noticed the included clamps have deeper ridges that actually bite into the thermoplastic for a leak-proof seal.
What Users Say
- Users who swapped out their old foil ducting report they no longer have to tape up tiny punctures every few months.
- Installers who work in cramped crawlspaces say the steel helix holds its shape even when snaked around heavy beams.
AC Infinity Flexible Four-Layer Ducting - (6" x 25')
Stop letting flimsy, leaky ducting compromise your entire ventilation setup. The AC Infinity Flexible Four-Layer Ducting is engineered to provide a durable, leak-proof, and reliable solution for any HVAC or indoor gardening application. It's the essential component for building a high-performance system, designed to work seamlessly with equipment like the Cloudline T6 inline fan.
Constructed with four robust layers, this ducting eliminates the risk of tears, cuts, and leaks that plague lesser-quality options. The inner layers of aluminum foil provide a fire-resistant barrier, while the outer layers of dual-layer thermoplastic protect against punctures. A strong internal steel-wire helix maintains the duct's shape and allows for incredible flexibility, making it easy to route around corners and obstacles. This 6" x 25' ducting is a core part of the extensive AC Infinity ecosystem, perfect for pairing with carbon filters and other ventilation accessories to achieve total environmental control.

FAQs
How do I cut this ducting to the desired length?
You can easily cut the ducting using a pair of wire cutters to snip the internal steel-wire helix and a utility knife to slice through the foil and thermoplastic layers. Always wear gloves for safety.
Is this ducting suitable for high-temperature applications?
Yes, the aluminum layers provide excellent fire resistance, making it suitable for a wide range of applications, including heating, ventilation, and air conditioning (HVAC) systems, as well as grow room exhaust.
What makes this four-layer ducting better than standard ducts?
The multi-layer design provides superior durability, preventing common issues like pinhole leaks, tears, and punctures. This ensures that your ventilation system operates at maximum efficiency without losing air pressure.
Can I use this ducting with fans from other brands?
Absolutely. This ducting has a standard 6-inch diameter, making it compatible with any 6-inch inline fan, exhaust fan, or carbon filter flange, regardless of the brand.
What other components might I need for a complete setup?
For a complete system, you will typically need an inline fan and a carbon filter. We recommend a complete air filtration kit which bundles all the necessary components for easy setup.
How do I set up a complete ventilation system in my grow tent?
Setting up an effective system involves positioning your fan and filter for optimal airflow, usually with the filter inside at the top of the tent. For a detailed walkthrough, check out our in-depth guide on AC Infinity kits.
