The AC Infinity Cloudline H4 is sealed to IP65 against moisture, dust and spores. It moves 212 CFM through 4\" ducting at just 27 dBA, keeping humidity and CO2 stable while it brings in fresh air.\u003c\/p\u003e\n\u003cp\u003eThe included speed controller sets airflow across 10 precise levels with a single button. A PWM-controlled EC motor lets the Cloudline H4 run smoothly at very low RPM without motor noise, drawing 18 W on average. Backup memory restores the last speed setting automatically after a power interruption.\u003c\/p\u003e\n\u003cp\u003eA mixed-flow design with stator blades and dual hydrodynamic wind circles delivers 324 Pa of static pressure. That keeps air moving through filters and longer duct runs. Dual ball bearings are rated for 67,000 hours and allow horizontal or vertical mounting. The motor box detaches from its mounting bracket for cleaning.
