Prima Klima’s K1603 Industry Line Carbon Filter is a refillable exhaust filter designed for reliable odour control in small to mid‑size grow setups. It uses a 4 cm deep bed of highly activated CTC75 carbon to maximise contact time and adsorption efficiency. The unit connects via a 125 mm flange, measures 400 mm in length (without flange) and 205 mm in outer diameter, and includes the K1703 fabric pre‑filter. Maximum airflow is rated at 460 m³/h, with an optimal operating range around 360 m³/h. Robust metal press parts and an extra‑long flange support secure, low‑leak installation. Typical pairing is with 125 mm inline fans and ducting on the extraction side of the system to scrub outgoing air while reducing unwanted odours.
