See the user manual

A2000 Commercial Scent Diffuser — 2000 m³ / 70 629 ft³, HVAC Connectable, 1000 ml / 33.81 fl oz / 60 Days

The A2000 is a mid-large commercial scent diffuser built for hotels, 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 2000 m³ / 70 629 ft³ — no wet residue, no smoke.

Three-in-one mounting — desktop, wall-mounted (expansion screws), or HVAC connectable. Place the A2000 on a desktop, mount it on a wall with the included expansion bolts (solid concrete or brick wall required), 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 A2000 running about 60 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 WD Aroma 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. MOQ flexible for first orders. Wholesale direct from our China factory with 9 years of B2B supply experience.

FAQ:

Q1. What is the A2000 and what model line is it part of?

A: The A2000 is a mid-large commercial scent diffuser from WD Aroma’s metal-housing A series. The full series covers: A600 (600 m³ / 21 188 ft³, 160 ml), A2000 (2000 m³ / 70 629 ft³, 1000 ml), A3000 (3000 m³ / 105 944 ft³, 1000 ml), A6000 (commercial floor-standing). A2000 sits between A600 and A3000.

Q2. What are the dimensions and weight of the A2000?

A: Product size 200 × 145 × 285 mm / 7.87 × 5.71 × 11.22 in. Net weight 2.9 kg / 6.39 lb. Gross weight 3.2 kg / 7.05 lb. Single box 25 × 19 × 37 cm / 9.84 × 7.48 × 14.57 in. Carton 38 × 50 × 38 cm / 14.96 × 19.69 × 14.96 in for 1 unit, 14 kg / 30.86 lb per carton.

Q3. How does the A2000 noise level compare to everyday environments?

A: ≤36 dB at 1 m distance, between a quiet library (≈30 dB) and a normal office (≈50 dB). For reference: rustling leaves 20 dB / quiet library 30 dB / A2000 36 dB / normal conversation 60 dB / city traffic 70 dB / vacuum cleaner 75 dB. The A2000 is unobtrusive in hotel rooms, meeting rooms, and bedrooms at night.

Q4. What is the voltage and power consumption of the A2000?

A: DC 12 V input, ≤12 W power. Ships with a 12 V power adapter. Power consumption is equivalent to a small LED light bulb — running 24/7 for a month costs less than USD 1 in electricity (at typical China commercial rates).

Q5. How does room height (ceiling) affect the A2000 coverage?

A: For a standard 3 m / 9.84 ft ceiling, ≈667 m² / 7 178 ft². For a 4 m / 13.12 ft ceiling (industrial / loft), ≈500 m² / 5 383 ft². For a 5 m / 16.40 ft ceiling (warehouse / atrium), ≈400 m² / 4 306 ft². Ceiling height × floor area should not exceed 2000 m³ / 70 629 ft³ total.

Q6. How long does a refill last at different usage intensities?

A: At 8 h/day (default hotel): ~60 days. At 12 h/day (retail): ~40 days. At 16 h/day (24-h supermarket / hospital): ~30 days. At 24/7 continuous (airport lounge): ~20 days. Each refill is 1000 ml / 33.81 fl oz. Consumption rate: ≥2.08 ml/h / ≥0.0703 fl oz/h at default spray/pause cycle (10s on / 600s off).

Q7. What kind of essential oil should I use with the A2000?

A: Pure essential oil, aroma oil or fragrance oil — waterless, no dilution required. Compatible with WD Aroma’s full essential oil catalogue (500+ stock scents + custom blending). We recommend oils specifically formulated for HVAC and commercial diffusers (low viscosity, no carrier oils) to avoid residue build-up. Avoid thick oils (pure vetiver, patchouli) and any oil with vegetable carrier.

Q8. Can I use the A2000 continuously 24/7?

A: Yes. The A2000 is rated for continuous commercial use. PP + Metal alloy housing, built-in powerful fan, and nano-atomization core support 24/7 operation. Recommended maintenance: each time you refill essential oil, clean the atomizer core with alcohol and wipe the housing with a towel.

Q9. What tools and steps are needed for each mounting mode?

A: Desktop — no tools, plug and play. Wall hanging — drill, level, 6 mm masonry bit, screwdriver; mount aluminum alloy back stick into studs or concrete (not drywall alone); slide A2000 on. HVAC — 1 m HVAC hose + copper fitting (sold separately or bundled); cut into HVAC return duct, secure with hose clamps, plug in. Install time: desktop 1 min, wall 15 min, HVAC 30-45 min by licensed HVAC technician.

Q10. Can the A2000 connect to an HVAC system?

A: Yes. The air mist duct is connected to the air conditioning outlet/inlet, making every corner of the building full of fragrance. For whole-building scenting, we recommend one A2000 per 2000 m³ / 70 629 ft³ zone. Multi-zone installations (e.g., 6000 m³ / 211 887 ft³ building) require 3-4 A2000 units. Compatible with central air, split AC, and VRF systems.

Q11. What wall types can the included wall hanging back stick support?

Q11. What is the wall mounting method for the A2000, and what is included in the box?
A: The A2000 is wall-mounted with expansion screws (not adhesive backing). Two expansion screws and two screws are included in the default accessory kit. No back stick / no wall sticker is included — solid concrete or brick wall is required for secure mounting.

Full default accessory kit (per the A2000 spec sheet): 1 m HVAC hose × 1 / HVAC copper connector × 1 / atomizer core × 1 / key × 1 / sealing ring × 1 / screws × 2 / expansion bolts × 2 / 12 V power adapter × 1.

Q12. Can I install the A2000 outdoors?

A: No. The A2000 is designed for indoor use only. For outdoor / semi-outdoor spaces contact us for IP-rated alternatives.

Q13. Does the A2000 support Tuya / Smart Life / Alexa / Google Home?

A: The A2000 is shipped with Bluetooth App control included by default (no extra charge). For non-smart SKU models (which ship without smart control), smart control can be added — per the price list: smart control upgrade MOQ 1000 units for non-smart SKU / 500 units for commercial diffuser. Bluetooth APP connection add-on: +$2.24 USD/unit. WiFi connection add-on: +$3 USD/unit. Note: A2000 already includes Bluetooth App, so no upgrade fee applies.

Q14. How many diffusers can I control in one app account?

A: There is no hard limit on the number of A2000 units a single app account can pair with — the system is built around a multi-device, multi-user architecture, so one property manager can group lobbies, guest rooms, spa zones, and back-of-house units under shared or role-based access.

For very large deployments (hospitality chains, multi-property estates, etc.), we recommend confirming the exact concurrent-control ceiling with your sales engineer at the quoting stage, because the practical limit depends on the router, network topology, and the firmware build loaded on the unit.

• Pairing: one app → many diffusers, many users
• Concurrent-control ceiling: depends on site network; confirm with sales for 50+ unit rollouts
• Firmware updates: pushed over-the-air through the same app, included for the life of the unit

Q15. Can the A2000 work without the app?

A: Yes. The A2000 has 4 onboard buttons (MODE / SET / UP / DOWN) for full manual control: timer, scent intensity, mode, on/off. The app is optional but recommended for advanced scheduling and multi-device management.

Q16. What are the OEM / ODM MOQ and tooling costs?

A: Per the price list notes:
Private label / brand logo (self-brand): 0 MOQ, no minimum order quantity.
ODM design fee: starting from USD 450, depending on customization complexity.
No tiered discount model — pricing is based on actual configuration (smart control add-on, color customization, etc.), not order volume discount tiers.
A2000 default inclusions (no extra charge): Bluetooth App, programmable timer, regional adapter.
Color customization: MOQ 500 units.
Mold / shape customization: MOQ 1000 units.
