Caluma’s Axial Fan 125 mm 2‑stufig is a two‑speed inline duct fan for small to mid‑sized grow tents. The 125 mm (12.5 cm) connection fits standard ducting and filters. A built‑in two‑position switch selects preset airflow rates of 285 or 350 m³/h to match intake or exhaust needs. Power consumption is 35 W. The unit is supplied wired for immediate use and includes four plastic feet for stable placement or mounting. Pairing with a matching 125 mm activated‑carbon filter and ducting is recommended by the brand for complete ventilation setups. Designed for continuous operation, it helps maintain stable humidity and temperature by moving fresh air through the tent efficiently without complex controllers.
