Pro Filter 125x475

RAM’s Pro Filter 125x475 is a cylindrical activated-carbon filter for grow‑room odour control. It uses virgin Australian RC412 carbon with a very fine 0.02‑micron pore size and is compacted to minimise air gaps, improving adsorption of volatile smells. In this size, the filter matches 125 mm ducting and is rated for a maximum recommended fan flow of 350 m³/h. The 125 mm neck and 475 mm body length suit mid‑size tents or small rooms, and the metal housing with internal mesh supports stable airflow. Intended for exhaust‑side use in extraction systems, it scrubs outgoing air before it leaves the space. RAM notes inline drying/dehumidifying during filling and expansion foam at the neck to maintain compaction and consistent filtration.
