AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust - desertcart.com

Review: Durable and Reliable 8-Inch Aluminum Ducting – Perfect for Ventilation and Exhaust - The AC Infinity Flexible 8-Inch Aluminum Ducting (8 feet long) is a fantastic choice for anyone setting up or upgrading a ventilation system. I use mine with an AC Infinity inline fan, and the results have been excellent—it moves air efficiently while staying strong and secure. The four-layer protection (dual aluminum foil, PET, and steel wire spiral) makes this ducting not only flexible but also very durable. It doesn’t tear or kink easily like cheaper ducting, and the extra thickness helps keep it from collapsing under pressure. The flexibility makes it easy to route through tight corners, and installation was straightforward with the included clamps. ✅ Pros: Heavy-duty four-layer construction for long-lasting use Flexible design makes installation easy, even in tight spaces Works perfectly with inline fans, grow tents, hydroponics, and HVAC setups 8-foot length is versatile for most setups Comes with sturdy clamps for secure attachment ❌ Cons: A little stiffer than thinner ducting, but that’s the tradeoff for durability At 8 feet, you may need extensions for larger setups 💡 Tips: Use with an AC Infinity inline fan for maximum airflow efficiency. When cutting to size, make sure to trim cleanly and secure ends tightly with clamps to avoid air leaks. If using in a miner room or greenhouse, pair it with a soffit vent to direct air outside effectively. Avoid bending too sharply—keep smooth curves for better airflow. Bottom Line: This ducting is built to last and does its job extremely well. Whether you’re cooling a miner setup, venting a grow tent, or upgrading your HVAC system, the durability and flexibility make it worth the investment.

## Questions & Answers

**Q: What is the fully compressed length of the 8FT 4" diameter duct?**
A: 5 1/2 inches

**Q: Is this safe to vent a portable ac? ac's can get really hot.**
A: I've never owned a portable AC. If there is a 4"  circle shaped vent hole on the portable AC, it should tolerate the heat. Stationary ACs condensate water, there is no vent hole.

**Q: anyone use this for garage auto exhaust tube?**
A: I am currently using this to exhaust the air in my wood shop

**Q: Is this suitable for marine use?**
A: No paperwork came with it indicating whether it is USCG compliant (if there is such a requirement).  If you want to use it as a duct for a bilge blower, I would say go ahead and use it.  If you are concerned about fire retardancy, I suggest you contact the seller first.
