Airontek’s Filter 150-400 is a cylindrical activated‑carbon odor filter designed for extraction lines in indoor grow rooms. This model uses a 150 mm flange and measures 400 mm in length (15 × 40 cm), with a rated airflow capacity of up to 500 m³/h. It connects directly to an extractor, forcing air through packed carbon where odors and contaminants are adsorbed before exhaust. The line is manufactured in Italy and uses uniform extruded 4 mm carbon pellets to promote low dust and consistent performance. Airontek recommends matching filters so capacity exceeds the fan’s effective airflow by roughly 20–30% to preserve contact time and prevent overloading. Suitable for 150 mm ducting where a compact, mid‑capacity exhaust filter is required.
