Cloudline PRO S Series is AC Infinity’s inline duct fan offered by Global Air Supplies for controlled grow‑room ventilation. It includes a wired 10‑speed speed controller, runs a quiet, efficient EC motor, and uses a mixed‑flow impeller for pressure performance through ducting and carbon filters. The range is available in 100, 150, 200, 250 and 315 mm sizes; the 100 mm model is rated at 348 m³/h and 28 dBA. The fan integrates with the AC Infinity UIS ecosystem for optional automation via compatible controllers; the supplied S‑series controller is manual only and the system is not compatible with G.A.S controllers. Typical applications include intake or exhaust in tents and rooms where stable temperature, humidity and odour control are important.
