Prima Klima Carbocone K4604-200 is a cylindrical activated‑carbon exhaust filter designed for 200 mm ducting. It uses Prima Klima’s patented conical inner basket to promote even carbon saturation and longer service life. The filter contains 13.1 kg of virgin carbon and ships with a K3704 dust pre‑filter. The housing measures 1000 mm in length (without flange) and 280 mm in body diameter, while the 200 mm flange connects to standard 200 mm fans and ductwork. The rated maximum airflow is 1400 m³/h, suitable for large extraction systems. Metal press components and an extended flange improve mechanical stability and sealing. Typical use is odour control on the exhaust side of indoor grows or similar ventilation setups.
