CarboAir 50 315x1000mm is a cylindrical activated-carbon exhaust filter for grow-room odour control. It uses a 50 mm bed of virgin granular carbon and a 55.5% open mesh to balance contact time with low resistance. The 315 mm diameter, 1000 mm length housing is handmade in Europe and supplied with a machine‑washable pre‑filter. Manufacturer data and brand‑listed retailers rate this size at a maximum airflow of 3100 m³/h, suitable for pairing with 12-inch extraction systems. The filter can be installed vertically or horizontally and is compatible with popular RVK, Revolution and other inline fans. Intended for extraction duty in small to large spaces; use a pre‑filter to extend service life and maintain performance.
