Prima Klima Carbocone K3604-200 is a cylindrical activated-carbon odor filter for exhaust ventilation in grow rooms and industrial spaces. It uses 100% virgin CTC75 pellets in a patented conical inner basket to promote even saturation, boosting adsorption efficiency and service life by up to 30% compared with conventional straight-wall designs. The K3604-200 features a 200 mm flange and is 1000 mm long (without flange), with an outer diameter of 280 mm. Maximum rated airflow is 1400 m³/h. A washable pre-filter sleeve (K3704) is included to capture dust and extend the carbon bed’s life. The metal housing and long flange provide a stable, secure connection to ducting and inline fans while maintaining low resistance for efficient, continuous odor control.
