Waterless nebulizing diffuser · Model 2410 aluminium alloy
Aluminium Alloy Waterless Essential Oil Diffuser 2410
This alloy waterless essential oil diffuser uses cold nano-atomization to break pure oil into 1-3 micron dry mist. No water, no heat, no wet residue, no smoke. It covers 187.5 m³ / 6 621 ft³ from a 20 ml / 0.68 fl oz glass bottle at 0.2-0.74 ml/h - about 50 m² / 538 ft² of floor at a 3.75 m / 12.3 ft ceiling - and runs at ≤36 dB on a 2000 mAh battery. The anodised body comes in 8 colourways with a flat or interchangeable A / B / C high head. Wholesale direct from our China factory.
Floor area by ceiling height
3.75 m / 12.3 ft50 m² 538 ft² 187.5 m³ ÷ ceiling height
Scent is dosed by volume, so the fixed figure is 187.5 m³. Floor area is that volume divided by your ceiling height - double the height and the area halves. Open-plan rooms, atriums and stairwells count as one connected volume. Spaces with heavy fresh-air exchange or doors held open need de-rating; air-change data is confirmed per project, never estimated.

Heads share one thread, so a spare head re-styles existing stock without a new SKU. The head surcharge is the same at every quantity.
Looking for the lower-cost PP version?
The PP shell 2410 runs the same internals in a 285 g / 0.63 lb plastic body, black or white only, from $7.75.
View the PP 2410 page →Anodised alloy waterless essential oil diffuser, 187.5 m³ from a 20 ml bottle
The alloy 2410 is an alloy waterless essential oil diffuser for hotel rooms, retail corners, offices, cars, bathrooms and studios up to 187.5 m³ / 6 621 ft³. An air pump forces pure oil through a venturi nozzle. The nozzle shears it into a 1-3 micron dry aerosol. Nothing is heated and no water is added, so the oil molecule stays intact. You get scent throw without wet residue, without smoke and without dilution.
Oil draw runs 0.2-0.74 ml/h / 0.007-0.025 fl oz/h across the three atomization levels. A 20 ml / 0.68 fl oz glass bottle is standard. The same thread also accepts 5 ml / 0.17 fl oz and 10 ml / 0.34 fl oz bottles, so sample kits and hotel amenity programmes share one machine.
The 2000 mAh battery charges over Type-C at DC 5V 1A and draws 3 W. Runtime tracks the interval you pick: 70 h at level 1, 20 h at level 2 and 7 h at level 3. Noise stays at ≤36 dB, quiet enough for a bedside table or a consultation room.
Why the anodised shell earns its $1.61
The shell is aluminium alloy over PP structural parts with a glass oil bottle. Anodising builds an oxide film into the surface instead of laying paint on top. The finish resists scratching from housekeeping trolleys and corrosion in bathrooms, spas and poolside rooms. Net weight is 420 g / 0.93 lb, and that mass is what stops a unit sliding off a marble counter.
Nine anodised colourways ship at no surcharge: black, silver, grey, blue, green, pink, gold, red and white. Because colour is free, a hotel group can colour-code by floor or brand tier with no price penalty.
One nozzle decision, three intervals, four timer states
Choose a flat head or one of three interchangeable high heads, A, B or C. All three cost the same +$0.32 and share one thread. A box of spare heads restyles existing stock instead of creating new SKUs.
One top touch key cycles atomization: 10 s spray / 170 s sleep, 30 s / 150 s, or 90 s / 110 s. The timer key cycles 1H → 2H → 3H → always-on and auto-shuts down at the set hour. Both settings sit in memory, so an unplugged unit returns to the same profile.
Built for unattended commercial duty
A tilt cut-off stops the pump when the body leans past 45°. It resumes 5 seconds after the unit is upright, which protects the pump from oil flooding during cleaning. Three indicator flashes signal 15% battery remaining.
Wholesale direct from our China factory. OEM / ODM and private-label work are supported. We engrave your logo on the sample unit at no extra charge – the engraving is free, the sample unit itself is charged at the 1 pc price. Every unit ships with free replacement spare parts and online technical support.

One option to choose: the nozzle head
This page covers the Aluminium alloy shell only. Every unit on it shares the same 69 x 69 x 120 mm / 2.72 x 2.72 x 4.72 in body, the same 187.5 m³ / 6 621 ft³ output and the same 2000 mAh battery. Two things move the unit price: the order quantity, which sets the tier, and the nozzle head, which adds +$0.32 on top of it. Colour is free.

Looking for the lower-cost PP version?
The PP shell 2410 runs the same internals in a 285 g / 0.63 lb plastic body, black or white only, from $7.75. Shell material is a separate product page, not a variant, so each shell keeps its own price list, colour chart and photography.

User manual
The 24xx manual covers key functions, the three atomization gears, timer cycling, memory behaviour, charging states and safe-use limits. Buyers reselling into retail may reprint it under their own brand as part of a private-label order.
Open the 24xx manual PDF (324 KB)Safe use extract
- Do not invert or tilt a filled unit - oil will drain into the pump and cause permanent damage.
- Operate between 10 °C and 50 °C / 50 °F and 122 °F.
- Switch the unit off before changing oil.
- For long storage, remove the nozzle and store it separately from the body.
- Do not modify or disassemble - this voids warranty.
Bottle change and level setup in 5 steps
Source: WD Aroma 24xx user manual. Total time about 2 minutes, no tools.
- Switch the unit off. Press and hold the power button for 2 seconds until every light is out. Never change oil while the pump is running.
- Release the bottle from the base. Push the bottle up from the bottom of the body to release the nozzle assembly, then unscrew the bottle from the nozzle.
- Fill and refit. Fill with neat essential oil, screw the bottle back onto the nozzle, then align the mark on the bottle holder with the mark on the body.
- Select the atomization level. Short-press the power key to cycle 10 s / 170 s, 30 s / 150 s and 90 s / 110 s. The chosen level is stored in memory.
- Set the timer. Press the timer key to cycle 1H, 2H, 3H and always-on. Display units offer 1H, 2H, 3H and 6H instead.
Certification
CE, FCC and RoHS apply to this platform per the supplier quotation sheet. Certificate copies and the per-market document list are issued with your quotation. Additional market approvals are quoted.
No engraving charge
Logo engraving on your sample unit
Order one sample unit at the 1 pc tier price and we laser-engrave your logo on it at no extra charge, so you approve placement, depth and contrast on the actual shell before the production run. The engraving service is free; the sample unit itself is charged at the 1 pc price. Send vector artwork with Pantone references. Volume logo work across the order, printed sleeves and custom retail boxes are quoted separately.
Buyer questions
How much oil should I budget per room per month?
Work from the level, not the bottle. At level 1 a 20 ml / 0.68 fl oz bottle runs about 70 h, so an 8 h housekeeping cycle gives roughly 9 days per room. At level 3 the same bottle drops to about 7 h, or under one day. A 30-room property running 8 h daily at level 1 therefore burns roughly 100 bottles a month; the same property at level 3 burns closer to 900. Quote your oil budget off the level you will actually run.
What is the real difference between the high heads A / B / C?
They are 3 cosmetic top profiles on one common thread, all at the same +$0.32. Mist output, particle size and oil draw are identical because the pump and venturi sit inside the body, not in the head. Buy a spare head to re-style existing stock instead of opening a second SKU.
Older listings for this model say 600 sq ft, 100 m³ or 48 hours. Which figure is right?
The specification sheet is the source of record and it says 187.5 m³ / 6 621 ft³ coverage, 0.2-0.74 ml/h oil draw and 70 h / 20 h / 7 h of bottle life on levels 1 / 2 / 3. The 48-hour figure on legacy listings was standby time, not spray time, and the 100 m³ figure predates the current nozzle. Quote the sheet figures to your customers.
Which oil bottles fit, and can I use my own retail bottles?
The nozzle takes standard 5 ml / 0.17 fl oz, 10 ml / 0.34 fl oz and 20 ml / 0.68 fl oz bottles. Unscrew the cap from a retail bottle and thread the bottle straight onto the nozzle, or decant into the empty glass bottle that ships fitted. Thick carrier oils, resins and anything with wax will clog the venturi - stick to neat essential oil and oily synthetics.
How does the running cost compare with an ultrasonic diffuser?
An ultrasonic unit dilutes oil into water, so the scent throw per millilitre of oil is far lower and the tank needs cleaning. This platform sprays neat oil at 0.2-0.74 ml/h and puts no water into the room, which is why it can sit next to laptops and mirrors. The trade is oil cost: you spend less on labour and refills of water, more on oil per hour at level 3.
What happens if a guest knocks it over?
Past 45 degrees the tilt sensor cuts the pump. Stand it upright and it resumes after about 5 s. The bottle threads onto the nozzle rather than sitting loose, so a knock does not empty oil into the carpet. That is the reason this platform is cleared for car cup holders and bathroom shelves.
Can I get this model with a digital display?
A display build exists on this platform at +$0. It replaces the always-on timer slot with a 6H position and shows battery state on the panel. It is not a picker option on this page - put "display" on your RFQ and we build that version.
Is the sample unit free, or just the engraving?
The engraving is free. The sample unit is not. You pay the 1 pc tier price for the diffuser itself ($12.00 on this model), and we laser-engrave your logo on it at no extra cost - there is no setup fee, no plate fee and no minimum for the engraving. That is the whole of what "free" covers here. Quoted separately: volume logo work across the production order, printed sleeves, custom retail boxes and any artwork redraw. Send vector files with Pantone references. Tooling or design fees, if any, are on request - we do not carry a standing number for them.
How is 187.5 m³ measured, and what do I buy if it is not enough?
It is cubic volume, not floor area: divide by ceiling height. At 3.75 m that is about 50 m² / 538 ft²; at 3.1 m about 60 m² / 646 ft². Above that, step up to the mains-powered commercial range - see our A2000 commercial scent diffuser or the wider ultrasonic diffuser category for HVAC-tied installations.
What are the lead time, warranty and pump service life?
MOQ is 500 pcs with a 30% deposit, delivery ex Huizhou, priced at $10.66 per unit at that quantity. The pump is model 370. Air-pump service life, warranty period and current lead time are on request: they move with batch and season, so we confirm them on the quotation instead of publishing a figure. Certification on file is CE, FCC and RoHS.
