M6000 Commercial HVAC Scent Diffuser
The M6000 is a commercial HVAC scent machine built for hotels and large venues: factory-rated 6000–8000 m³ / 211 888–282 518 ft³ coverage from two external 1000 ml / 33.81 fl oz bottles. Each nozzle has its own pump and control panel, so two different scents can follow independent weekly schedules at the same time. Two-fluid nano atomization connects directly to central air-conditioning ductwork; free-standing and wall-mounted placement are supported. Aluminum-alloy housing in black, DC 12 V, <50 dB, Bluetooth APP, 1-year warranty. No MOQ, four wholesale tiers from $69.79 per pc, wholesale direct from our China factory.
Floor area by ceiling height
3.75 m / 12.3 ft1 600 m² 17 222 ft² 6 000 m³ ÷ ceiling height
Scent is dosed by volume, so the fixed figure is 6 000 m³. Floor area is that volume divided by your ceiling height - double the height and the area halves. Open-plan rooms, atriums and stairwells count as one connected volume. Spaces with heavy fresh-air exchange or doors held open need de-rating; air-change data is confirmed per project, never estimated.

Buyer questions
Why is the M6000 coverage given as a range, 6000–8000 m³?
Coverage depends on three site conditions: ceiling height, HVAC airflow when the machine is ducted in, and how much the room is ventilated. A closed room with strong supply-air throw reaches the upper end; a high-ceiling or heavily ventilated space works closer to the lower end. Send your ceiling height and floor plan and we will confirm the figure for your project.
How does the 6000–8000 m³ rating convert to floor area?
Divide the volume by ceiling height. At a 3 m / 9.84 ft ceiling: about 2000–2667 m² / 21 528–28 704 ft². At 4 m / 13.12 ft: about 1500–2000 m² / 16 146–21 528 ft². At 5 m / 16.40 ft: about 1200–1600 m² / 12 917–17 222 ft².
When do I need more than one M6000?
Add units when walls, doors or partitions break the space into separate air zones, since fragrance cannot cross a closed door; one M6000 per 6000–8000 m³ zone is the rule of thumb. In a single open hall, one ducted unit with well-spaced outlets normally covers the whole volume. Contact us with a floor plan for a unit-count and outlet layout.
How does the M6000 compare with ordinary small scent machines?
An ordinary machine on the market covers roughly 300 m³; the M6000 at 6000–8000 m³ is about 20–27 times that, and additionally provides two pumps, two bottles and HVAC duct connection that small desktop units do not have. For a single-bottle metal machine with smaller coverage, compare the rest of our metal diffuser line.
Can the two sides run two different fragrances at the same time?
Yes. Each nozzle has its own air pump, its own control panel and its own bottle, so the two sides are fully independent scenting zones. Two different scents can run simultaneously on different weekly schedules — for example a fresh lobby scent and a warmer corridor scent.
How do I install and refill the two external bottles?
Slide each 1000 ml bottle into its holder at the side of the machine and connect its small pipe; the bottles stay outside the housing, so refilling or swapping a scent is done in place without moving the unit. Refill with pure essential oil using a funnel, then reconnect the pipe.
What oil can I use, and can I supply my own fragrance?
Use pure essential oil, aroma oil or fragrance oil — waterless, with no dilution. We can run a compatibility test on customer-supplied oil before a branded order. Low-viscosity oils formulated for commercial and HVAC diffusers atomize best; very thick oils and carrier-oil blends mist more lightly and can narrow the tube over time.
Will the two fragrances mix, and can I run only one side?
The scents do not mix inside the machine because each side has a separate pump, pipe, bottle and nozzle; they only meet after leaving the outlets with the room air. Either side can be switched off independently, so the M6000 can also be used as a single-scent machine with the second bottle as reserve.
How are the four HVAC connection pipes used?
The box contains two large pipes and two small pipes, four in total. The small pipes run from the back of the machine to the bottle holders; the large pipes fit above the bottle holders and their other ends connect into the air-conditioning supply or return duct. Insert each pipe fully into its fitting before running the unit.
What are the steps for connecting the M6000 to central air-conditioning?
Cut an opening into the supply or return duct, secure the large pipes to the duct with clamps, route the small pipes to the bottles, then plug in the DC adapter and set the schedule from each panel. We recommend having a licensed HVAC technician carry out the duct work; typical installation takes about 30–45 minutes once the duct position is chosen.
Can the M6000 be used without HVAC ductwork?
Yes. It can stand free on the floor or a sturdy surface, or be wall-mounted; in both modes the dual nozzles scent the room directly. Duct connection is only needed when you want fragrance distributed through the building's own air system to multiple rooms.
How many air outlets can one M6000 feed?
The supplier installation reference shows up to five outlet points from one ducted unit. The practical number depends on duct length and fan pressure; for long duct runs or outlets spread across several floors, contact us to confirm sizing so fragrance stays even at every outlet.
How do I set the weekly schedule on the button panel?
Each zone is set separately with its CYCLE, MODE, SET, UP and DOWN buttons: choose the days (Monday to Sunday shown on the panel), set the working period such as 08:00–22:00, set the spray interval, then choose the concentration level. The schedule repeats weekly until changed.
How do I connect the Bluetooth APP, and can several staff use it?
Install the companion app on your phone, enable Bluetooth, and pair with the machine from the app to control schedules and scent levels from the phone. There is no subscription fee, and multiple phones or staff members can be given access for sites such as hotel chains. Bluetooth works within phone range of the machine.
Does the M6000 keep running without a phone connected?
Yes. Schedules are stored on the machine itself, so once the weekly program is set from the panel it runs independently, with no phone present and no internet connection. The Bluetooth APP is an alternative way to control the unit, not a requirement for operation; WiFi control is not supported.
What are the four wholesale price tiers, and can I order a sample first?
USD EXW per piece: sample 1 pc at $80.00; 10–49 units at $80.29; 50–999 units at $71.65; 1000 or more units at $69.79. There is no MOQ, so a sample or trial order is welcome; freight and import duty are not included.
What does OEM customization include?
OEM covers laser-engraved logo on the aluminum housing, custom packaging and a branded manual; there is no MOQ for standard units and small customization batches are accepted. Send your logo file and the quantities you need and we will confirm customization details and lead time on the quotation.
Which certifications, warranty and replacement parts come with the M6000?
The M6000 is built to CE and RoHS, with certificate copies provided with the order, and carries a 1-year warranty backed by online technical support. Replacement wear parts — pumps, nozzles, pipes and control boards — can be supplied after the order; contact us for availability and shipping.
