Product Summary
The AC-MAX is a split-type HVAC scent diffuser built for large indoor commercial interiors. The machine and the fragrance oil tank are separate components, and the unit connects directly to central HVAC ducts so scent is delivered through the building's existing airflow system instead of from a single point in a room. A 5L oil bottle feeds the atomizer, and one unit is rated to cover approximately 2,500-3,500 m² (8,000-10,000 m³ or 25,000-35,000 ft²). The unit runs on DC12V at 48W, consumes 6ml ±5% of fragrance oil per hour and operates below 45dB. Wi-Fi and Bluetooth control cover adjustable working schedules, fragrance intensity and password protection for project management. A silver aluminum body with a net weight of 4.2kg keeps installation on HVAC runs straightforward.
