K40 1800m³ Countertop Touch Commercial Aroma Diffuser Waterless Scent Machine

Where does the K40 commercial aroma diffuser fit in the RAMOND K Series?

In the RAMOND K Series the suffix marks the control tier: base models are run by touch keys, S models add Bluetooth, and Pro models add WiFi. The K40 is the touch tier in its countertop expression: the same 1800 m³ coverage class as the series' floor-standing column, but packaged as a white rounded box that sits where people actually are, at desk and counter height.

• Base tier = touch keys on the machine, for venues that adjust levels in person rather than over an app

• 1800 m³ of coverage matches the floor-standing column in this series; the format, not the volume, decides which one a project needs

• Pump-pressure two-fluid atomization, oil-based specialty fragrance only

• White rounded metal countertop body: 23.5 × 14 × 30 cm, 4.35 kg net, 4 units per export carton

How much floor area can one K40 cover?

Coverage is stated in air volume: 1800 m³ per unit. Commercial ceilings commonly 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 600–640 m² band. Match the examples below to your own rooms; for larger footprints, our guide to choosing a scent diffuser for large spaces scent diffuser for large spaces walks through multi-unit layouts.

Why pump-pressure atomization instead of ultrasonic?

The K40 atomizes with an air pump, not a vibrating plate. Oil is fed through a two-fluid nozzle and sheared into a dry cold mist. No water is added and nothing is heated. Because this unit works closer to people than any other format, that dryness is non-negotiable: guests at a front desk or salon chair must never feel moisture in the air, while ultrasonic units trade it for a low price and a water tank you must keep filled and descaled. The table below sums up the trade-off.

How is the K40 placed and installed?

Installation is placement, not construction. Four facts define the setup:

• White rounded metal body sits on front desks, counters and cabinet tops (23.5 × 14 × 30 cm, 4.35 kg net)

• Blue display and light strip face the guest side; the nozzle throws from the top deck, so leave headroom above the placement surface

• Extension duct included in the box

• Runs from a 12V⎓2A / 24 W plug-in adapter with a 1.5 m cable (CN plug standard); ships as unit + manual + extension duct + accessory pack + adapter

The extension duct ships in the box as supplied; any custom duct routing is a topic to settle with our team during specification rather than a feature claimed on this page. For projects that integrate scenting into central air handling, read how to install an HVAC scent diffuser how to install an HVAC scent diffuser and review the ducted-capable K31S/K51S.

How much oil does the K40 use?

Rated consumption is 4.5 ml per hour of continuous output (0.0013 ml per second), drawn from the 500 ml tank. Runtime per intensity level is confirmed with your quotation: share the daily hours your front-of-house runs and the quotation will state the refill interval for your own duty pattern, sized on your venue rather than a generic assumption.

Consumption is published as the rated per-hour figure; refill calendars are issued with the quotation against your actual duty pattern. Intermittent operation extends the interval rather than shortening it.

How do you run the K40 day to day?

Control lives on the machine. The touch panel beside the blue display sets output levels directly, and the light strip signals run status visible from across the counter: staff adjust in seconds, guests touch nothing. This machine-set control is the base tier of the ladder running through our commercial scent diffusers commercial scent diffusers; the Pro tier adds WiFi where remote management becomes worth the step.

Which venues get the most from a K40?

Four venue types show where a near-person 1800 m³ countertop unit earns its slot:

Hotel front desks & guest lounges

The check-in counter is where brand impression and staff workflow meet. A white rounded unit behind the desk covers the lounge plate on mid levels, and the light strip lets the concierge see at a glance that the machine is running.

Beauty salons

Salon chairs sit metres from the machine all session long, exactly where wet vapor would be felt. Dry cold mist from the counter keeps the air fragrant without humidity, and the rounded white shell suits a treatment-room palette.

Bank branch halls

Waiting areas need a calm, consistent ambience during banking hours. A unit on the back counter covers hall and waiting zone together, and tellers adjust levels on the touch panel without calling a vendor.

Esports hotels & guest floors

Lobby and corridor runs on guest floors need coverage that does not clutter shared space. A cabinet-top unit throws down the corridor from one point, and the blue display sits low-key against the interior.

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 this close to guests?

Distance is exactly the point. The K40 works at desk and chair distance, where any moisture in the mist would be felt immediately: pump-pressure two-fluid atomization keeps the output dry, with no water tank to refill. Ultrasonic units suit back rooms where humidity is acceptable, not guest-facing counters.

How does the K40 differ from a floor-standing touch column?

Both cover 1800 m³ on the same pump-pressure platform; the format decides the job. The floor-standing column throws across a hall from a distance, while the K40 sits at counter height near guests (front desks, salon reception, bank halls), where the blue display and light strip read as part of the interior. The K40 also ships with an extension duct included in the box.
