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.
