Product Summary
The A300 is a commercial scent diffuser built for indoor scent marketing in medium and large venues. Its steel housing and 500ml fragrance oil tank are designed for continuous duty in hotel lobbies, shopping malls, banks, hospitals, showrooms and retail stores. A built-in fan moves atomised fragrance oil through the room for faster and more even distribution, while the 12W DC12V drive keeps running cost predictable.
Operators set diffusion schedules and fragrance intensity on the TFT colour touch screen or through the AromaOS smart app. The unit can stand alone, be wall-mounted, or be connected to HVAC ducting. Noise stays below 40 dB, so it can work in guest-facing areas without disturbing conversation.
Key Features
500ml oil tank at 4ml ±10%/h consumption — fewer refill trips for maintenance teams; at the rated rate one tank covers roughly 125 hours of diffusion.
500-800 m2 coverage (1500-2500 m3 / 5000-8500 ft2) — one A300 serves a hotel lobby or an open retail floor instead of several small units.
Steel housing — a metal body intended for long-term commercial use in high-traffic public interiors.
Built-in fan — pushes fragrance further and evens out concentration across the space.
TFT colour touch screen plus AromaOS app control — schedule diffusion windows and adjust intensity without walking to the machine.
12W DC12V operation and under 40 dB noise — low power draw and quiet running for guest-facing areas.

Working environment
Indoor commercial spaces
Models and Options
The A300 is supplied in two steel housing colours: white and black, so the unit can be matched to light hotel interiors or darker retail fixtures.
Three working configurations are supported on the same model. Standalone use suits reception desks and showroom floors; wall-mounted installation frees floor space and keeps the diffuser above head height; HVAC connection introduces fragrance into existing ducting where air already moves between rooms.
Control can be local through the TFT colour touch screen and manual buttons, or remote through the AromaOS app for schedules and intensity. Buyers should confirm model and placement against actual space size and airflow before ordering.
Materials and Structure
The body is a steel housing, finished for commercial interiors and built to withstand daily handling in public areas. Cold-air atomisation converts fragrance oil into fine particles without heat, and a built-in fan distributes them through the room. The 500ml reservoir sits inside the L231 x W105 x H271 mm chassis, powered from a DC12V supply at 12W. Wall-mount and HVAC connection points let the same chassis serve floor, wall and duct layouts. Packing measures L300 x W150 x H370 mm, with a gross weight of 4.4kg against 3.8kg net.
Applications
Hotel lobbies and corridors — consistent arrival scent across a 500-800 m2 lobby.
Retail stores and shopping malls — scent marketing that supports customer experience and odour control.
Offices, banks and showrooms — wall-mounted or standalone placement at quiet, under 40 dB operation.
Hospitals and clinics — odour control in waiting and reception areas.
HVAC-served buildings — duct-connected diffusion where several rooms share one air system.
