AC Infinity 4-Inch Duct Carbon Filter XL (Extra Large Australian Charcoal)
Product Overview
Maximize your ventilation endurance and eliminate intense odors with the AC Infinity 4-Inch Duct Carbon Filter XL. Engineered with an elongated chamber, this extra-large model contains an expanded carbon bed designed to trap pollutants over an extended lifespan. It pairs seamlessly with 4-inch high-airflow inline fans to provide superior molecular scrubbing without choking your air velocity.
Best Use & Applications
  • High-Odor Grow Tents: Built for 2x2, 2x4, and 3x3 setups containing highly aromatic cultivars that overwhelm standard-sized filters during peak flower.
  • Extended Growing Cycles: Ideal for cultivators wanting fewer filter replacements, as the expanded volume extends continuous usage cycles.
  • High-Volume Extraction Lines: Optimized for small indoor spaces requiring an accelerated cubic feet per minute (CFM) replacement rate to cool down heavy lighting setups.
  • Concentrated VOC Workspaces: Excellent for filtering heavy organic compounds, paint fumes, laser smoke, or 3D printer emissions in compact hobby rooms.
Key Features & Technological Highlights
  • Expanded Australian Virgin RC412 Core: Densely packed with top-tier activated charcoal grading over 1200+ IAV (Iodine Adsorption Value). The extra-long 16-inch body fits a much larger surface area to trap pollutants efficiently.
  • Reversible Flanges: Includes heavy-duty aluminum flanges that detach easily from both ends. By reversing the hardware, you change the primary air contact area, extending the carbon filter's functional life span by up to 33%.
  • Stainless Steel Open-Surface Mesh: Constructed with a dual-sided mesh framework maximizing up to 53% open-surface area. This structural design allows peak airflow passthrough, minimizing backpressure on your inline fan.
  • Heavy Duty Mounting System: Designed with integrated aluminum anchor hooks built onto the flanges. These clip directly into the included suspension kit to eliminate sagging in upper grow tent supports.
