K31Pro
RAMOND Aroma
Product Description
Inside the RAMOND K Series, the control tier decides the suffix: base models run on keys, S models add Bluetooth, and Pro models add WiFi. The K31Pro is the WiFi workhorse for mid-to-large interiors: more volume than the compact Bluetooth desktops, yet still a countertop-format machine you can carry between zones.
Pro tier = keys + WiFi (mini-program/APP), stepping past Bluetooth-only compact models
800 m³ of coverage places it above the 400–500 m³ compact units in the same series
Pump-pressure two-fluid atomization, oil-based specialty fragrance only
Black sheet-metal countertop body: 27 × 12.5 × 27 cm, 3.7 kg, 6 units per export carton
Coverage is stated in air volume: 800 m³ per unit. Ceiling heights in most commercial interiors run 2.8–3 m, so convert with a simple ratio: floor area ≈ volume ÷ 3.0 down to volume ÷ 2.8. That places one machine in the 270–285 m² band. Match the examples below to your own rooms; if your venue runs larger still, our guide to choosing a scent diffuser for large spaces scent diffuser for large spaces walks through multi-unit layouts.
Space type | Volume | Suggested units |
|---|---|---|
Hotel lobby + main corridor | ≈700 m³ | 1 unit |
Shopping-mall atrium (single floor plate) | ≈2,400 m³ | 3 units |
Office tower reception hall | ≈1,600 m³ | 2 units |
Car showroom | ≈800 m³ | 1 unit |
The K31Pro atomizes with an air pump, not a vibrating plate. Oil is fed through a two-fluid nozzle and sheared into a dry cold mist, with no water added and nothing heated. The mist therefore stays dry enough for a unit sitting metres from guests on a counter or shelf, while ultrasonic units trade that dryness for a low price and a water tank you must keep filled and descaled. The table below sums up the trade-off.
| Pump-pressure (K31Pro) | Ultrasonic diffuser |
|---|---|---|
Working principle | Air pump drives oil through a two-fluid nozzle | High-frequency vibration breaks water into mist |
Water required | None; runs on pure fragrance oil | Tank must be kept filled with water |
Mist character | Dry cold mist, no heat involved | Cool but wet vapor that can settle |
Upkeep focus | Refill oil and keep the nozzle clear | Regular descaling of the ultrasonic plate |
Best fit | Guest-facing counters, shelves and lobbies | Small back rooms where humidity is acceptable |
Installation is placement, not construction. Four facts define the setup:
Footed black sheet-metal body stands on counters, cabinet tops or equipment shelves (27 × 12.5 × 27 cm, 3.7 kg net)
Top carry handle repositions the unit between zones without tools
Runs from a 12V⎓1A / 12 W plug-in adapter with a 1.5 m cable (CN plug standard)
Ships as unit + manual + accessory pack + adapter; the nozzle sits on the top deck, so leave headroom above the placement surface
Ducted scenting through central air handling is not this model's route; that capability belongs to the K31S/K51S. If your project requires HVAC integration, read how to install an HVAC scent diffuser how to install an HVAC scent diffuser and shortlist those models instead.
Consumption is 0.00253 ml per second, about 9.1 ml per hour of continuous output. A full 500 ml tank therefore stretches across weeks, and the four intensity levels pace it further: A1 lasts ≈94 days, A2 ≈71 days, A3 ≈48 days and A4 ≈25 days per fill. Quote these measured levels as they stand; the duty pattern you run decides where your own calendar lands.
Refill-cycle settings (measured, current model range)
Setting | Measured refill cycle |
|---|---|
A1 | ≈94 days |
A2 | ≈71 days |
A3 | ≈48 days |
A4 | ≈25 days |
Runtime is published per intensity level (A1–A4) as measured figures, with no percentage estimates added. Intermittent operation extends the calendar rather than shortening it.
Two control layers ship in the box. At the machine, an LED display shows weekday, time and status icons above a four-key AI · M · + · − panel, so levels are set directly on the unit. Over WiFi, the mini-program/APP takes care of remote management, the Pro-tier control stack within our commercial scent diffusers commercial scent diffusers. No Bluetooth pairing is involved: the Pro suffix is the WiFi tier.
Four venue types show where an 800 m³ WiFi unit earns its slot:
A reception hall plus its corridor run is a tall, open 600–800 m³ volume. One unit on the back counter scents both, and the carry handle lets night staff move it to the breakfast area without a second install.
Atrium plates run 2,000 m³ and up, so malls stage two or three units along the primary walkway. WiFi management keeps every unit on the same daytime rhythm from one phone.
First impressions form at the turnstiles. A unit behind the reception desk covers the entry hall on mid levels, and the keypad lets building staff adjust it without calling a vendor.
Showrooms pair tall ceilings with display cars that must stay dry. A dry-mist unit on the office shelf scents the floor without water vapor settling on paint or glass.

Every export carton holds 6 units. Each machine ships with the diffuser, manual, accessory pack and a 12V⎓1A adapter (CN plug standard). The packed product measures 31.5 × 17.5 × 32 cm; the master carton is 65 × 54.5 × 34 cm at ≈27 kg gross, with each unit at 3.7 kg net / ≈4.5 kg gross.
The tank is built for oil-based specialty fragrance only, never water or water blends.

What are the MOQ and lead time?
Black is the standard color and is available for normal order cycles; any other color starts at 500 units per color. Your exact MOQ, lead time and shipping terms are confirmed with your quotation.
Which certifications does the unit hold?
The K31Pro carries product certification and a certified patent record. Certificate copies are shared for named-market discussions rather than listed on the page; request the pack for your destination market via quality and technology quality and technology.
What warranty applies?
Warranty length and coverage depend on the destination market and order volume. Our team will confirm the applicable terms in writing with your quotation.
Why pick pump-pressure over ultrasonic for a unit that sits on a counter?
Placement is the reason. A counter or shelf unit works metres from guests and display goods, so the mist must stay dry; pump-pressure two-fluid atomization delivers that with no water tank to refill. Ultrasonic units suit back rooms where humidity is acceptable, not guest-facing surfaces.
How does WiFi control help with several units or several sites?
Each unit is set directly on its LED keypad, then joined to the mini-program/APP over WiFi. At the control layer this means one phone can check and adjust every machine, across zones in one building or units in different branches, without walking to each unit. Site-level rollout details are best confirmed with our team during specification.
Send your floor area, ceiling height and zone list, and we will return a placement map showing where each K31Pro commercial aroma diffuser should stand, how many units the project needs, and the oil budget for a quarter.
