K72Pro
RAMOND Aroma
Product Description
The K Series ladder runs base (keys or touch), S (+Bluetooth) and Pro (+WiFi). Within the twin-head pair, the Bluetooth twin serves the same two-zone brief from a phone, while the K72Pro is the WiFi half: remote mini-program/APP management across a whole fleet, plus dual 1000 ml aluminum bottles feeding its two heads. Pick it when the machines will be checked from a phone at headquarters, not only at the machine.
Pro tier = keys + WiFi (mini-program/APP), the fleet-management alternative to the Bluetooth twin-head
Coverage rated 4000 m³ ×2: two heads, each covering 4000 m³
Pump-pressure two-fluid atomization, oil-based specialty fragrance only
Sheet-metal chassis with dual aluminum bottles: 56 × 17.2 × 31.5 cm, 10 kg net, 2 units per export carton
Coverage is stated as 4000 m³ ×2: each of the two heads carries a 4000 m³ rating. Ceiling heights in commercial interiors run 2.8–3 m, so convert per head with a simple ratio (floor area ≈ volume ÷ 3.0 down to volume ÷ 2.8), which places each head in the 1330–1430 m² band. One machine can therefore serve a lobby and a ballroom side by side, or pair with a second unit for a single giant hall; 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 grand lobby + ballroom as two zones | ≈3,800 + ≈2,600 m³ | 1 unit |
Shopping-mall atrium + main walkway | ≈7,200 m³ | 1 unit |
Exhibition center, single hall | ≈7,800 m³ | 1 unit |
Airport departure concourse section | ≈11,000 m³ | 2 units |
Each K72Pro head 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. The mist stays dry enough for units working above banquet tables and exhibition stands, 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 (K72Pro) | Ultrasonic diffuser |
|---|---|---|
Working principle | Air pump drives oil through a two-fluid nozzle | High-frequency vibration breaks water into mist |
Water required | None; it 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 the aluminum bottles and keep the nozzles clear | Regular descaling of the ultrasonic plate |
Best fit | Two-zone halls under one remote-managed fleet | Small back rooms where humidity is acceptable |
Installation is placement, not construction. Four facts define the setup:
Sheet-metal chassis measures 56 × 17.2 × 31.5 cm and 10 kg net, standing on a counter, cabinet top or platform
Two 1000 ml aluminum bottles mount left and right of the chassis, both visible and reachable for swaps
Runs from a 12V⎓4A / 48 W plug-in adapter with a 1.5 m cable (CN plug standard)
Ships as unit + manual + accessory pack + adapter; leave working clearance at both bottle ends
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 listed at 0.0074 ml per second, about 26.6 ml per hour of continuous output. Each head carries its own 1000 ml aluminum bottle, and the measured pace per intensity level reads: A1 lasts ≈64 days, A2 ≈48 days, A3 ≈33 days and A4 ≈17 days per fill. Quote these 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 | ≈64 days |
A2 | ≈48 days |
A3 | ≈33 days |
A4 | ≈17 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. On the machine, keys set weekday, time and intensity directly. Over WiFi, the mini-program/APP supervises the whole fleet: the Pro-tier control stack within our commercial scent diffusers commercial scent diffusers. One phone can check and adjust every unit across zones in a building or branches in a city, which is what the twin heads and dual bottles are managed for.
Four venue types show where a 4000 m³ ×2 WiFi unit earns its slot:
Atrium plates run 4,000 m³ and up per floor. One dual-head unit staged on back-of-house shelving fields the atrium and the primary walkway, while the WiFi APP keeps both heads on the same trading-hours rhythm from a single phone.
Halls of 7,000–8,000 m³ suit a single machine running both heads into the same volume. Organizers adjust intensity between build-up, show days and teardown from the mini-program/APP without walking the hall.
A lobby and its ballroom are two zones with different calendars. One machine covers both, one head per zone, and the banquet manager shifts intensity per floor from the WiFi APP before events.
Tall banking halls need steady, quiet coverage during opening hours. The keypad sets the base schedule once; head-office facility teams then check and adjust every branch machine over WiFi.

Every export carton holds 2 units. Each machine ships with the diffuser, manual, accessory pack and a 12V⎓4A adapter (CN plug standard). The packed product measures 69 × 56 × 44.5 cm, with each unit at 10 kg net / ≈11 kg gross and each carton at ≈22 kg gross.

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.
The K72Pro 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.
Warranty length and coverage depend on the destination market and order volume. Our team will confirm the applicable terms in writing with your quotation.
Zoning is the reason. Two heads rated 4000 m³ ×2 let one installation serve a lobby and a ballroom differently, or double the throw into a single giant hall, while the dual 1000 ml aluminum bottles double the oil carried on site, all from one power point and one managed device.
Each unit is set directly on its 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 K72Pro commercial aroma diffuser should stand, how many units the project needs, and the oil budget for a quarter.
