AC Infinity Air Filtration Kit PRO 4 inch inline fan system
This complete PRO 4 inch system pairs a CLOUDLINE PRO EC inline fan with a smart controller. It adds an Australian carbon filter and 25 ft of ducting. The kit moves up to 205 CFM at just 29 dBA to clear heat, humidity, and odor from a grow tent. The mixed-flow EC motor runs quietly and sips power.
Smart inline fan, carbon filter, and ducting combo
The Controller 69 PRO automates fan speed from temperature, humidity, and VPD, with timer, cycle, and schedule modes set from the AC Infinity app. Growers keep root and canopy conditions steady while the fan holds a target climate on its own. A 38 mm bed of virgin charcoal scrubs odor from reservoirs and flowering plants before air leaves the tent. IP-44 housing, dual ball bearings, and a steel filter body handle humid rooms. The kit includes clamps, a prefilter, and rope-clip hangers for a fast install.
