Commercial Scent Diffusers A3000

See user manual

A3000 Commercial Scent Diffuser — 3000 m³ / 105 944 ft³, HVAC Connectable, 1000 ml / 33.81 fl oz / 50 Days

The A3000 is a large commercial scent diffuser built for hotel lobbies, B&Bs, retail stores, supermarkets, gyms, brand boutiques, large living rooms and corridor scenting. Nano-atomization technology breaks essential oil into ultra-fine dry mist that spreads evenly across rooms up to 3000 m³ / 105 944 ft³ — no wet residue, no smoke.

Three-in-one mounting — desktop, wall-mounted, or HVAC connectable. Place the A3000 on a desktop, mount it on a wall with the included aluminum alloy back stick, or connect it to a central air system for whole-building scenting. Same unit, three installation modes. PP + Metal alloy housing in matte black blends with modern hotel and commercial interiors.

Built for 24/7 commercial use. A 1000 ml / 33.81 fl oz refillable oil tank keeps the A3000 running about 50 days on one fill (8h/day, 10s on / 600s off cycle). Nano-atomization core with built-in powerful fan accelerates diffusion for faster, more even scent spread. ≤36 dB (≤38 dB per spec sheet) — quiet enough for hotel rooms and meeting rooms.

Smart APP remote control. Bluetooth 5.0 + WiFi dual protocol works with the companion app — supports week scheduling, start/end time, custom spray/pause cycles, work / work-night / normal modes, and fan & pump level adjustment, all from your phone.

Wide application. Suited for hotel lobby, hotel room, bedroom, living room, corridor, B&B, clothing store, supermarket, gym, and other entertainment venues. Suitable for home use, retail spaces, and large entertainment venues.

OEM/ODM available: laser logo, private label, custom colour, custom shape. MOQ flexible for first orders. Wholesale direct from our China factory with 9 years of B2B supply experience.

FAQ:

Product Line & Specs

Q1. What is the A3000, and where does it sit in the product line?
A: The A3000 is the largest commercial scent diffuser in WD Aroma’s metal-housing A series, sitting above the A600 (600 m³ / 21 188 ft³, 160 ml) and A2000 (2000 m³ / 70 629 ft³, 1000 ml). Built for large commercial projects — hotel lobbies, conference centres, mall atriums. For coverage above 3 000 m³ / 105 944 ft³, step up to the M series: the M6000 (8 000 m³ / 282 518 ft³) for HVAC large spaces, and the M8000 for floor-standing installs.

Q2. Where can I find the full A3000 spec sheet?
A: The complete spec table sits at the top of the product description. Key numbers: 240 × 145 × 285 mm / 9.45 × 5.71 × 11.22 in, net 3.5 kg / 7.72 lb, coverage 3 000 m³ / 105 944 ft³, tank 1 000 ml / 33.81 fl oz, noise ≤38 dB(A), DC 12 V / ≤12 W. Carton size and weight are confirmed per order.

Q3. Is the A3000 noisy?
A: At 1 m, the A3000 runs at ≤38 dB(A) — quieter than the 40-50 dB background of most commercial HVAC systems, so it adds no audible hum in lobbies or corridors and stays unobtrusive in guest rooms at night. Reference: library 30 dB / A3000 38 dB / office 50 dB / conversation 60 dB.

Q4. Voltage and power consumption?
A: DC 12 V at ≤12 W — about a small LED bulb. At typical China commercial rates (≈0.85 RMB/kWh), 24/7 operation uses 8.64 kWh per month, costing roughly 7.3 RMB / USD 1+. A 12 V power adapter ships in the box.

Capacity & Coverage

Q5. How does ceiling height affect coverage?
A: Coverage scales inversely with ceiling height: 1 000 m² / 10 764 ft² at 3 m / 9.84 ft, 750 m² / 8 073 ft² at 4 m / 13.12 ft (industrial / loft), 600 m² / 6 458 ft² at 5 m / 16.40 ft (warehouse / atrium). Total zone volume must not exceed 3 000 m³ / 105 944 ft³.

Q6. How long does a refill last?
A: At the default 10 s on / 600 s off cycle: ~50 days at 8 h/day (hotel lobby default), ~33 days at 12 h/day (retail), ~25 days at 16 h/day (24-h supermarket / hospital corridor), ~17 days at 24/7 (airport lounge). Each refill is 1 000 ml / 33.81 fl oz. For reference: a 12 h/day hotel lobby cycles oil ~11 times a year; a 24-h supermarket ~22 times a year. Intensity is adjustable via the 4 onboard buttons (Q15).

Q7. Which essential oils can I use?
A: 100% pure essential oils, aroma oils, or fragrance oils — waterless, no dilution. For brand-specific scent profiles, our factory supplies 500+ stock formulations plus custom blending. Heads up: avoid high-viscosity oils (pure vetiver, patchouli) and any with a vegetable carrier (jojoba, sweet almond, olive, etc.) — they clog the atomizer core. For HVAC-integrated projects (Q10), specify low-viscosity oils designed for continuous diffusion.

Q8. Can the A3000 run 24/7?
A: Yes. The A3000 is rated for continuous commercial duty — PP + metal-alloy housing, built-in high-output fan, and nano-atomization core are all designed for 24/7 operation. Typical deployments: 24-h convenience stores, airport VIP lounges, hotel lobbies running around the clock. Maintenance: clean the atomizer core with alcohol and wipe the housing at every refill.

Installation & HVAC

Q9. What are the three mounting modes and how do I install each?
A: Desktop — any flat surface, plug and play. Wall — the back panel has 2 pre-drilled keyhole slots; fix with the 2× M4 × 25 mm Phillips screws + 2× 7 mm five-point rubber wall plugs (drill 7 mm holes) into solid concrete or brick. HVAC — cut a 30-40 mm opening in the return duct, attach with the included 1 m hose (best cut to ≈35 cm for a secure fit and optimal diffusion) + copper fitting, clamp, and plug in. Step-by-step illustrated guide ships in the box.

Q10. How do I connect the A3000 to an HVAC system?
A: Use the included 1 m hose (best cut to ≈35 cm — secure fit, best diffusion) + copper fitting to connect the A3000 mist outlet to the AHU return or supply duct. Sizing rule: one A3000 covers 3 000 m³ / 105 944 ft³ — a 9 000 m³ / 317 832 ft³ building takes 3 A3000s. For projects ≥ 6 000 m³ / 211 888 ft³ where 3 A3000s aren’t cost-effective, step up to the HVAC-specialised M series: M6000 = 8 000 m³ / 282 518 ft³ per unit, so 2 × M6000 covers 16 000 m³ / 565 035 ft³. Compatible with central AHU, split AC, and VRF systems.

Q11. Which wall types are safe to hang the A3000 on?
A: Fully loaded, the A3000 weighs 4.5 kg / 9.9 lb (3.5 kg empty + 1 L oil ≈ 1 kg), so adhesive mounting is out. Safe walls: solid concrete, brick, wood studs — the included M4 × 25 mm screws + 7 mm rubber wall plugs hold fine. Unsafe walls: hollow drywall, plasterboard without a stud, glass, metal — 4.5 kg will pull out. Drywall fix: add a plywood back-board across 2 studs, or use M6 toggle bolts (user-supplied, not in the box).

Q12. Can the A3000 go outdoors?
A: No. The A3000 is indoor-only (IP20 rated). For outdoor, semi-outdoor, poolside, or sauna spaces, contact our sales team for IP65-rated alternatives.

Smart App Control

Q13. Does the A3000 support app control?
A: The A3000 ships with Bluetooth App control included by default (no extra charge), supporting iOS and Android. The app is free. For WiFi control, add the WiFi module at order time: +$3 USD/unit for the Bluetooth + WiFi dual-mode version. The smart-control module is configured at order time and is not field-retrofittable.

Note on Button-only SKUs: the A3000 is also available as a Button-only unit (no Bluetooth, no WiFi) for projects that prefer absolute simplicity — these are quoted on request via sales. For all other deployments, the Bluetooth default is recommended.

Q14. How many A3000 units can I run from one app account?
A: One app account pairs with multiple A3000s simultaneously. Each unit can be custom-named (e.g., “Lobby 1”, “Room 302”) for easy multi-zone management. Firmware updates push over-the-air, free for the life of the unit.

Q15. Can the A3000 work without the app?
A: Yes. The A3000’s 4 onboard buttons (MODE / SET / UP / DOWN) handle everything: timer, scent intensity, mode, on/off. The button layout matches the A2000 / A600, with 4 intensity levels. For any deployment where stability is the priority, the button-based timer mode is the most reliable option — the app is best for centralised management and complex scheduling, but for hotel guest-room night modes or hospital sterile zones, run the unit on its buttons.

Wholesale & Customisation

Q16. What is the price, MOQ, and tooling cost?
A: Unit price (Bluetooth App included as default): Sample $84.00 / 10-49 units $80.29 / 50-999 units $78.44 / ≥1000 units $77.82. Add-on: +WiFi $3 USD/unit (upgrade to Bluetooth + WiFi dual-mode).
