300m³ Wall Mounted Scent Diffuser Remote-Control Unit

Where does the remote-control dome sit in the RAMOND J line?

The remote-control dome sits in the RAMOND J line for homes, guestrooms and small commercial spaces, a line whose coverage ratings span 90–550 m³. This unit takes the 300 m³ class in a dome form that mounts on the ceiling, the wall, a floor stand or a spotlight rail. Buyers who want app-based control or higher coverage in the same family can step up to the Bluetooth tier of the line, and large commercial floors are covered by the commercial series elsewhere on our site.

• Waterless pump-pressure diffusion: dry cold mist, no water top-ups, no visible plume

• 300 m³ coverage class with a 120 ml tank drawing 2 ml/h continuously (0.00056 ml/s)

• White dome cylinder, φ13 × 15.5 cm, 0.621 kg; wall, floor-stand, drilled or drill-free ceiling, and spotlight-rail mounting

• Plug-in 12 V ⎓ 0.5 A / 6 W; hand-held remote control backed by a built-in memory battery

How much space does one ceiling dome cover?

One dome unit covers up to 300 m³; at typical 2.8–3 m ceilings, that is roughly 100–107 m² of floor area. Mounting high is part of how the rating works: scent released at ceiling level falls through the room's circulation instead of stopping at the first sofa, and a single unit holds connected volumes, such as a bedroom joined by a bathroom passage or a living room open to the dining zone. Match the examples below to your own rooms.

Water or no water? How this ceiling dome scents the air

The ceiling dome scents the air by pump-pressure atomization: a two-fluid, cold-air method that breaks pure fragrance oil into a dry, fine dispersion. No water enters the loop, so there is no tank to top up, no humidity added to the room, and no cool-mist plume near bedding, curtains or the garments on a shop rack. That matters most exactly where this unit is placed: bedrooms, guestrooms and entrance zones, where people and textiles sit closest to the unit. One condition to plan around: it runs on oil-based specialist fragrance oils, not water-soluble oils; the matched oil programme is listed further down the page.

What does mounting one involve — wall, ceiling or rail?

Ceiling, wall, floor stand or spotlight rail: the spec sheet lists five mounting routes, and the fittings come in the box. Fix the mounting plates following the manual, seat the dome, then connect power from the nearest outlet with the 1.5 m adapter cord. No ducting, no fixed wiring, and the room below keeps its sightlines. A standard placement checklist:

• Dome body φ13 × 15.5 cm, 0.621 kg; wall-mount, floor stand, drilled or drill-free ceiling, or spotlight-rail mount per the spec sheet

• Power input 12 V ⎓ 0.5 A / 6 W via the supplied adapter, cord length 1.5 m

• Tank 120 ml filled with oil-based specialist fragrance oil; continuous output 2 ml/h (0.00056 ml/s)

• Ships as unit + manual + mounting plates (lock and slide) + accessory pack + battery + adapter (CN plug standard); 12 units per export carton

Positions that work well: on the ceiling above the bedroom side of a bathroom passage, centered on an open living-dining floor, over a guesthouse room's luggage bench, or clipped to a spotlight rail just inside a shop entrance. Keep the unit clear of direct water spray in bathrooms and let the high position carry scent inward. Fixing details are covered by the manual and accessory kit in the package; for hotels and small chains planning a room standard, our team can advise placement points and unit counts per room type when you inquire.

How far does a 120 ml fill go?

Continuous output is 2 ml/h (0.00056 ml/s) from the 120 ml tank — the smallest fill in this coverage class, so refills sit on a steadier rhythm than with larger tanks. How long one fill lasts depends on the working setting and how many hours a day the unit runs. Measured refill cycles are shared with your quotation: send your room type and daily usage window with the inquiry and our team will plan the refill rhythm with you.

Refill frequency also follows the density you want: a bedroom used for sleep needs a gentler field than a shop entrance. Keep one oil profile per room type so the routine stays simple; the oil programme below covers single notes and layered blends for exactly that.

No phone needed: how is the dome unit controlled?

Control stays off your phone: the hand-held remote reads out on a small LCD display with dedicated power, mode and set keys, so households and housekeeping teams adjust output and working windows without an app, an account or a network connection. A built-in memory battery keeps your settings through power cuts, so the unit picks up where it left off. For buyers comparing control tiers across the catalogue, the commercial scent diffusers commercial scent diffusers of the K series step up to WiFi app control on their top tier; ask our team which level fits your property standard.

Where does a remote-control dome unit fit best?

Four kinds of space show where a ceiling dome earns its slot:

Bedrooms & bathroom passages

Mounted on the ceiling above the passage or high on the wall, the dome sends dry scent along the corridor into the bedroom: no humidity near bedding and no unit taking the nightstand.

Living rooms & dining zones

One unit over an open living-dining floor covers the connected volume; ceiling placement keeps outlets and shelving free for the room's own styling.

Guesthouse rooms

A white dome reads as part of the ceiling in a styled guesthouse room, and the remote rides in the housekeeping cart: turnover teams adjust each room's settings without logging into anything.

Small shop entrances

Scent meets customers at the door: a unit over the entrance zone holds the front floor of a boutique or salon, and dry mist never settles on clothing racks or displays.

What do buyers ask before ordering a dome unit?

Can I arrange a sample unit first?

For hotels, guesthouse groups and retail buyers, samples are usually the first step. Send your property list and timeline through our contact our team and our team will confirm the current sample arrangement; OEM and branding requirements are covered under our aroma diffuser custom services.

What are the MOQ and lead times?

MOQ and production lead time depend on the order volume and any custom requirements, so we quote them per project rather than quoting ballpark numbers. Share your project scale in the inquiry and the quotation will carry the exact figures.

Is the unit certified?

Yes. This dome unit ships as a quality-certified unit, and our quality and technology page outlines the approach behind it. For the documentation that applies to your market, ask together with your quotation and our team will confirm which certificates are current and share them.

What warranty applies?

Warranty terms are confirmed per order and per market, so the terms you receive match the units you order. Request the warranty schedule together with your quotation.

Pump-pressure or ultrasonic: which suits a bedroom or bathroom passage?

Ultrasonic diffusers vibrate a water-and-oil mixture into a visible cool mist. They add humidity and need regular water top-ups, so they are often kept away from textiles and passage zones. The ceiling dome works on pump-pressure atomization with pure oil alone: dry, invisible mist from the ceiling or a high wall position, no humidity added near bedding or entryway storage, and no water routine for housekeeping. In rooms where people live closest to fabrics, that difference usually decides the choice.

What does installation involve, and is the remote included?

Five mounting routes are listed on the spec sheet — wall, floor stand, drilled or drill-free ceiling, and spotlight rail — and the mounting plates, accessory kit, battery and adapter come in the box. The hand-held remote is part of the package, and the built-in memory battery keeps your settings through power cuts. Follow the manual for fixing details, or ask our team together with your room list.
