The CarboAir 50 Filter 315 x 660mm is a cylindrical carbon filter for grow‑room extraction systems. It features a 50 mm bed of virgin activated granular carbon and includes a machine‑washable pre‑filter to protect the media and sustain airflow. This 315 mm diameter, 660 mm length variant is rated up to 2100 m³/h and is designed to be fitted on the intake side of an extractor fan so air is pulled through the filter before being exhausted. Developed alongside Systemair and handmade in Europe, the 50 series targets odour‑causing VOCs while avoiding excessive restriction, making it a practical choice for small to mid‑size spaces and 12-inch ducted setups. Published airflow figures are laboratory tested to aid reliable fan matching.
