390m³ WiFi Wall Mounted Scent Diffuser Pull-Out Tank Unit with 200 ml

Where the pull-out tank unit sits in the RAMOND range

This WiFi pull-out unit sits in the upper-mid class of the RAMOND J line, a range for homes, guestrooms and small commercial spaces spanning 100 to 450 m³. Its 390 m³ rating covers generous suites and open living floors, and it pairs that reach with the connected control tier of the line: touch at the panel plus WiFi mini-program/APP management. Buyers who instead need scent across commercial floors and lobbies will find the K series floor and countertop units elsewhere on our site.

• Plug-in or battery operation with touch control plus WiFi mini-program/APP management

• 390 m³ coverage class with a 200 ml tank behind a pull-out drawer; bottles swap without dismantling the board

• Round nozzle above a vertical trim gives the board its wide-eye face; white PP body, 16 × 6.5 × 23 cm, 0.71 kg

• Ships as unit + manual + hook + accessory pack; 24 units per export carton

How much space does one pull-out unit cover?

Coverage is stated in air volume: one pull-out tank unit covers up to 390 m³. At typical 2.8–3 m ceilings that is roughly 130–139 m² of floor area: a generous guestroom suite, an open living-and-dining plan or a boutique showroom floor. Two siting conditions shape how the rating plays out: open, free-moving air distributes scent more evenly than partitioned corners, and rooms kept closed for long periods benefit from a position near the airflow path: mounted above head height, the board sends scent into the room's circulation rather than straight into one seat.

Water or no water? How this pull-out unit scents the air

The WiFi wall board scents the air by pump-pressure atomization: a two-fluid, cold-air method that breaks pure fragrance oil into a dry, fine dispersion. Because no water enters the loop, there is no tank to top up, no humidity added to the room, and no cool-mist plume near fabrics, bedding or display goods, the point that matters for a board that works metres from guests. One condition to plan around: the unit runs on oil-based specialist fragrance oils, not water-soluble oils; the matched oil programme is listed further down the page.

What does hanging or placing one involve?

Wall placement is a two-step job with the fittings in the box: fix the included hook to the wall following the manual, hang the board on it, then choose the power route: the wall supply for continuous operation, or the internal battery where an outlet is inconvenient. No ducting, no fixed wiring, and the surface below stays free. The pull-out drawer faces outward, so refills happen without taking the board down. A standard placement checklist:

• Body 16 × 6.5 × 23 cm, 0.71 kg; white PP board with the round nozzle above a vertical trim

• Runs at 12 V ⎓ 1 A / 12 W from the wall supply, or on the internal battery where outlets fall short

• Pull-out drawer carries the 200 ml bottle; slide it out to swap, no dismantling

• Ships as unit + manual + hook + accessory pack; 24 units per export carton

Positions that work well: beside a guestroom wardrobe or above head height along a bathroom entrance corridor, on the wall behind a shop counter, or flanking a showroom entry. Keep the unit clear of direct water spray in bathrooms and leave clearance for the drawer to slide out. Fixing details are covered by the manual and accessory kit in the package; for hotels planning a chain-wide standard, our team can advise placement heights and unit counts per room type when you inquire.

How do the 200 ml pull-out refills work?

The 200 ml bottle sits in a pull-out drawer, so a refill is a slide-and-swap rather than a dismantling job: the drawer design keeps housekeeping off a ladder and the board stays on its hook. How long one fill lasts depends on the working setting, the output level you choose and the running schedule of the space; our team maintains a measured consumption sheet that is shared with your quotation. Send your room type and usage window with the inquiry and we will plan the refill rhythm with you.

Refill frequency also depends on the density you want: a bedroom used for sleep needs a gentler field than a showroom that hosts walk-ins. Keep one oil profile per room type so staff can top up without re-deciding; the oil programme below covers single notes and layered blends for exactly that purpose.

Touch panel, WiFi app or both? How the unit is controlled

Daily control has two layers. The touch panel handles direct adjustments at the board; over WiFi, the mini-program/APP takes over remote management: check status and adjust output from a phone without walking to the unit, useful for teams covering several rooms or floors. For buyers comparing control levels across the catalogue, the commercial commercial scent diffusers shows the wider control stack; ask our team which level fits your property standard.

Where does a WiFi wall board fit best?

This WiFi wall board fits best in four kinds of space: hotel guestrooms and suites, bedrooms and living rooms, shops and showrooms, and salons and beauty studios. The notes below connect each space to the features above.

Hotel guestrooms & suites

The board hangs beside the wardrobe and scents the room before every arrival. Housekeeping swaps the 200 ml bottle through the pull-out drawer in seconds, and engineering can check each room's unit from the mini-program/APP instead of opening every door.

Living rooms & bedrooms

One board covers an open living-and-dining plan within its 390 m³ rating. Dry dispersion means no added humidity near curtains, sofas or bedding, and the touch panel adjusts levels without reaching behind furniture.

Shops & showrooms

A boutique floor around 130–139 m² is covered by a single board above the entry zone. Battery power keeps the display wall cord-free where outlets fall short, and the drawer refill means no ladder-side pouring between customers.

Salons & beauty studios

Treatment rooms run close to textiles and towels, so dry cold mist matters; the board sits above the entry door and the level changes between morning prep and back-to-back appointments, from the panel or from the app.

What do buyers ask before ordering a wall unit?

Can I arrange a sample unit first?

For hotel 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 for your order.

Is the unit certified?

Yes. This WiFi wall board ships as a quality-certified unit. Certificate copies are shared for named-market discussions via quality and technology quality and technology; request the pack for your destination market together with your quotation.

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.

How does WiFi remote management work?

Set the unit directly on its touch panel, then join it to the mini-program/APP over WiFi. At the control layer this means one phone can check and adjust the board without walking to it, useful when the unit serves a guestroom floor, several treatment rooms or a shop after hours. Site-level rollout details are best confirmed with our team during specification.

Plug-in or battery: how do the two power routes work together?

The board runs from either source: connect it to the wall supply for continuous operation, or let the internal battery carry it when an outlet is inconvenient or temporarily unavailable. Switching between the two needs no reconfiguration; the panel settings stay as you left them. To plan charging around housekeeping schedules, share your usage pattern with our team together with the inquiry.
