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.

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.
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.
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.
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.
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.
