AC Infinity Ducting
The AC Infinity Flexible Four-Layer Ducting is a heavy-duty aluminium ventilation hose designed for ducting connections in grow rooms, grow tents, HVAC systems, dryers, bathrooms, attics, and AV equipment rooms. Its four-layer construction significantly outperforms the single-layer aluminium ducting commonly found at hardware stores, providing superior resistance to leaks, tears, punctures, and cuts during both installation and long-term use in demanding environments.
Starting from the inside out, the construction begins with a dual-layer heavy-duty aluminium foil inner core that is fire and flame resistant, critical when ducting runs near heat sources or within enclosed spaces. The outer shell is dual-layer PVC thermoplastic that protects the aluminium from physical damage, cuts, and tearing during routing through tight spaces and around obstacles. An internal steel-wire spiral runs the full length of the tube, maintaining its round cross-section under compression and allowing it to flex around corners and bends without collapsing or restricting airflow. The tube can be shortened by cutting to fit any installation precisely, and each roll includes two stainless steel duct clamps in the matching diameter for immediate installation without additional hardware.
Compatible with inline fans, carbon filters, air filter boxes, silencers, and any standard flanged ductwork component in the matching diameter. Available in 2.4 m (8 ft) and 7.6 m (25 ft) lengths to suit compact setups and full grow room installations. Note: the PVC outer layer will melt if exhaust temperatures exceed 80°C, do not use in high-temperature applications beyond this threshold. For a grower connecting a CLOUDLINE fan to a carbon filter and then to the tent exhaust point, the 7.6 m (25 ft) roll provides enough duct to complete most standard tent ventilation runs with material remaining for adjustments.

- Internal steel-wire spiral maintains round cross-section through bends and corners without collapsing
- Trimmable, cut to any required length with scissors or a sharp blade
- Two matching stainless steel duct clamps included with every roll
- Compatible with inline fans, carbon filters, air filter boxes, silencers, and all standard flanged ductwork components
- Available in 2.4 m (8 ft) and 7.6 m (25 ft) lengths
Directions for Use
expand_more
Directions for Use
- Measure the required ducting length for your installation before cutting, allowing extra for any bends or rises in the run.
- If shortening is required, cut the tube cleanly with scissors or a sharp blade.
- Slide one end of the ducting over the fan, filter, silencer, or ductwork flange and secure with one of the included stainless steel clamps. Tighten firmly to create an airtight connection.
- Route the ducting through the grow space, allowing the steel-wire spiral to flex around corners without pinching or collapsing the tube. Avoid sharp bends that could restrict airflow.
- Connect the remaining end to the next ductwork component and secure with the second included clamp.
- For additional joins or connections, seal with AC Infinity aluminium ducting tape to ensure airtight joints.
- Seal all duct port openings at the tent wall with aluminium ducting tape to prevent light leaks and unfiltered air bypass.
Note: Do not use in applications where air temperatures exceed 80°C (176°F). The PVC outer layer will melt above this threshold.
