Air Filtration Kit PRO 4" Grow Tent Fan System

The Air Filtration Kit PRO 4" combines a high-efficiency inline fan 4 inch with a smart controller, premium Australian carbon filter, and 25 ft of ducting to create a complete grow tent fan and filtration solution. Its CLOUDLINE PRO EC motor delivers up to 205 CFM of airflow at just 29 dBA, reducing hot spots and humidity swings in your grow tent while running quietly and efficiently.

Smart Inline Fan, Carbon Filter & Ducting Combo for Hydroponics

The included Controller 69 PRO automates your inline fan for grow tent with temperature, humidity, and VPD triggers, plus timer, cycle, and schedule modes you can adjust remotely via the AC Infinity app. A 4" grow tent carbon filter packed with 38 mm of Australian virgin charcoal scrubs odors before air exits through the flexible ducting, making this an ideal carbon filter fan combo for hydroponic grow rooms that need reliable, odor-free ventilation.

Key features:

  • Complete ventilation solution for hydroponics – Inline fan, smart controller, carbon filter, ducting, clamps, prefilter, and hangers all included for a plug-and-play grow tent exhaust setup.

  • Precise climate control (temp, humidity, VPD) – Controller 69 PRO automates fan speed based on temperature, humidity, and VPD, helping maintain optimal conditions for hydroponic root and canopy health.

  • Quiet, energy-efficient airflow – PWM-controlled EC motor and mixed-flow design deliver up to 205 CFM with low energy draw and just 29 dBA of noise, ideal for indoor grow tents near living spaces.

  • Powerful odor and VOC removal – 4" Australian virgin charcoal filter (1200+ IAV, 38 mm thick bed) effectively strips smells from nutrient solutions, reservoirs, and flowering plants before air is exhausted.

  • Durable, grow-ready construction – IP-44 rated housing, dual ball bearings (up to 67,000-hour lifespan), and corrosion-resistant steel filter body withstand humid hydroponic environments.

  • Flexible installation and control – 25 ft of 4" ducting, rope clip hangers, and multiple control modes (timer, schedule, cycle, app control) make it easy to dial in airflow and routing for any tent layout.
