AC Infinity Flexible Four-Layer Ducting – 4" to 12" (8ft & 25ft)

Cheap ducting has a habit of announcing itself: a pinhole tear, a crinkly roar, a joint that sags off the spigot. AC Infinity's Flexible Four-Layer Ducting is built so you never think about it. It's four laminated layers round a steel-wire spiral, finished in a matte black that disappears against a tent or ceiling, and it comes with the two stainless steel clamps you need to fit it.

Why this ducting

• Four-layer construction. More resistant to leaks, tears and cuts than single- or triple-ply foil ducting.
• Steel-wire spiral. Flexible enough to bend round corners, firm enough to hold a round bore for smooth, quiet airflow.
• Matte black outer. Low-glare and discreet.
• Two clamps included. Stainless steel duct clamps come in the box, so there's nothing extra to buy for a fan-to-filter run.

Sizes and lengths

4", 6", 8", 10" and 12", each in 8ft (2.4m) or 25ft (7.6m). Match the ducting to your fan and filter. The 25ft length is the better value per metre and can be cut down.

Not just for growers

• Grow tents and grow rooms
• Tumble dryer and portable air-con exhausts
• Kitchen, bathroom and workshop extraction

Rose's Pro-Tip

"Pull it out straight and cut it to length. Bunched-up ducting roars and steals airflow. Fit a noise reduction clamp between your fan and the ducting and the whole run goes quieter still."

FAQ

How do I cut it?
Cut the layers with a sharp knife and snip the wire with side cutters. Tuck the cut end of the wire inwards.

Does it fit non-AC Infinity fans?
Yes. The sizes are standard, so it fits any fan or filter with a matching spigot.
