Prima Klima K4600-100 is a Carbocone activated-carbon exhaust filter built for 100 mm ducting. It features a patented conical inner basket that promotes even carbon saturation, improves adsorption efficiency by up to 30%, and extends service life compared with classic cylinders. The filter body measures 50 cm long and 18 cm in diameter, using approximately 3.9 kg of granulated carbon behind a removable K3700 prefilter to capture dust before the bed. Rated for a maximum airflow of 400 m³/h, it suits small tents or rooms where reliable odour control and particulate reduction are required. Metal press parts and an extended flange help ensure stable mounting and leak-free connections within inline ventilation systems.
