Prima Klima’s K2604 Eco Line is a cylindrical activated‑carbon exhaust filter for 200 mm ducting, built to scrub odors from extraction air in medium grow spaces. The unit pairs a 3 cm bed of CTC75 virgin carbon with robust metal press parts and an extra‑long flange for a secure connection. Core specifications on the official page list a 200 mm flange, 280 mm body diameter, and 500 mm length (without flange). Maximum airflow is rated at 1000 m³/h, with an optimal range around 780 m³/h. The filter ships with a K2704 dust pre‑filter, weighs about 7.2 kg with 4.3 kg of carbon, and is refillable for extended service. Use with 200 mm inline fans on the exhaust side of your ventilation run.
