Do we hire scent machines for a launch or buy them? Buy them. A launch is a one-evening event but the machines are not one-evening equipment - they move into the sales gallery the next morning and run there for the life of the project. A SOSA Vaayu is ₹11,999 with a 400ml tank that lasts up to 75 days, which is usually less than a single evening's hire quote and it is still yours in year two.
How many machines does a launch actually need? Usually two or three. Count the separately moving bodies of air, not the zones on the floor plan: registration foyer, launch floor, sample flat. Each one up to 1000m³ is a SOSA Vaayu (₹11,999). A single volume of 8,000-10,000 sq ft, such as a banquet hall or a marquee, is one SOSA Angaan (₹25,999) rather than five small machines.

Facts verified 24 August 2026 against the live SOSA product pages: the SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³, described by the manufacturer as approximately 2,000-3,000 sq ft, with a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, Bluetooth app and button control, 1h/4h/8h/24h timers, operation under 38dB, dimensions of 165 x 80.5 x 215mm at 0.9kg on a DC 12V/1A 5W supply, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, and also runs standalone wall-mounted or lay-flat. Scent enhances the ambience and perceived quality of a space; it works alongside proper ventilation and cleaning and is not a substitute for either, and SOSA makes no claim that fragrance alone influences a purchase decision. The hotel-inspired scents are SOSA's own original interpretations; SOSA is an independent brand and is not affiliated with, or endorsed by, any hotel named for reference. Coverage, fragrance usage and running cost depend on the space, settings and hours of use, and are confirmed on a consultation. Prices and availability are subject to change - see the live product pages.
A project launch is the one evening a developer cannot repeat, and scent is the finish that gets specified last or not at all - so here is the entire setup in one page: what you buy, where each machine goes in a venue you do not own, what to run and when, and how the same kit carries on working in the sales gallery from the next morning.
Quick answers — read this first
What does a complete fragrance setup for a real estate project launch involve? Three things, in this order. One, a machine sized to each separately moving body of air - one SOSA Vaayu (₹11,999) covers up to 1000m³, about 2,000-3,000 sq ft, so a registration foyer and a launch floor are usually two machines. Two, one fragrance across every machine, chosen because it has to remain the project's signature for two years. Three, a run schedule that starts 45 minutes before doors, not at the moment guests arrive. A banquet-scale hall of 8,000-10,000 sq ft is one SOSA Angaan (₹25,999) instead.Do we hire scent machines for a launch or buy them? Buy them.

The short answer
Short answer: buy two or three machines rather than hiring - one SOSA Vaayu (₹11,999) per separately moving body of air up to 1000m³, about 2,000-3,000 sq ft, one fragrance across all of them, started 45 minutes before doors; a banquet or marquee hall of 8,000-10,000 sq ft takes one SOSA Angaan (₹25,999) instead.
The pick: the SOSA Vaayu (₹11,999) for the foyer, the launch floor and the sample flat, stepping up to the SOSA Angaan (₹25,999) when the launch hall itself is 8,000-10,000 sq ft.

In this guide
A launch setup is two or three machines and one fragrance, not a machine per zone. The count comes from the air volume of each separately moving body of air, and everything you buy for launch night keeps working in the sales gallery afterwards.

Straight answer
What does a complete fragrance setup for a luxury project launch actually involve?
Three decisions and about ₹24,000 of equipment, in most cases. First, the count. Work in cubic metres, not zones on a floor plan. One SOSA Vaayu (₹11,999) is rated to 1000m³, roughly 2,000 to 3,000 sq ft at normal ceiling height, so a registration foyer and a main launch floor are two machines, and the sample flat is a third. Where the launch hall is a single banquet or marquee volume of 8,000-10,000 sq ft, that is one SOSA Angaan (₹25,999) instead of five small machines fighting each other. Second, one fragrance. Order the same profile for every machine on site, and choose it knowing that whatever you pick on launch night usually becomes the project's signature for the next two years. Third, the schedule. Set the Vaayu app to start 45 minutes before doors so the fragrance has diffused and settled, and let it run at a low intensity through the evening instead of a burst as guests walk in. Launch venues are usually hired, so the practical details matter: both machines are waterless, so nothing damp or sticky lands on a rented carpet or a hired stage; the Vaayu is 0.9kg on a 5W supply and stands freestanding or wall-mounts; and the key-lock means a public crowd cannot change your settings. One honest caveat - a venue that still smells of paint, adhesive or a freshly laid floor needs curing and ventilation, and fragrance on top of that gives you both smells at once. A free scenting plan will size it from your venue plan, and a portion of every order supports girl-child education through Nanhi Kali.
Count the bodies of air, not the zones. One Vaayu per 1000m³, one fragrance across all of them, started 45 minutes before doors and kept low all evening.
The machine at the centre of almost every launch setup is the SOSA Vaayu - waterless, under 38dB, rated to 1000m³ (about 2,000-3,000 sq ft), 0.9kg on a 5W supply, with a 400ml tank that runs up to 75 days and a Bluetooth app timer you set to the run of show. Buy it for launch night, keep it for the gallery.

A launch setup has two machines in it and the difference between them is air volume. Both pictures link to the product page so your projects team can check the specification before the purchase order goes out.

A foyer where guests queue and hand over invitations is a separate body of air from the main hall. Give it its own machine on the same fragrance so the impression starts at the door rather than halfway through the evening.

The three parts of a launch fragrance setup
A launch setup is only three decisions, and developers usually get the first one wrong by counting zones on a floor plan instead of measuring air.
1
What you actually buy
Two or three machines, one fragrance, no hire contract
Measure each separately moving body of air, multiply length by width by height, and divide by 1000 to get your Vaayu count. A registration foyer is one. A launch floor up to about 3,000 sq ft is one. A sample flat is one. That is the whole shopping list for most launches, and it comes to less than the AV budget for a single evening. Resist the urge to add a machine per zone: five machines in one connected hall smell like five different rooms, which is exactly the impression a launch cannot afford.
Tip: buy, do not hire - the machines move into the sales gallery the morning after and run there for years.
The Vaayu is rated to 1000m³, about 2,000-3,000 sq ft, and weighs 0.9kg, so it travels from launch venue to gallery in a crate.

Where it goes in a venue you do not own
On the inward air path, never chasing an open door
Launch venues are hired, and hired venues have rules: no drilling, no ducting, no cabling across a walkway. Place the machine where air is genuinely moving inward - beside the air-conditioning supply, a few metres inside the entrance, on a plinth or a wall mount the venue approves. Do not put it at an open door. Launch doors stay open for hours, the fragrance walks straight out, and you end up running a strong setting to fight a draught you cannot win. Three metres inside the threshold does more than three times the intensity at it.
When the hall itself is one 8,000-10,000 sq ft volume, the Angaan covers 3,000m³ from a single standalone wall mount, no ducting required.
See SOSA Angaan →

What happens on day two
The launch kit becomes the sales gallery kit
This is the part that turns a launch expense into an asset. The morning after, the machines move into the sales gallery and the sample flat, the intensity drops a step, and the app schedule changes from a four-hour event to gallery opening hours. The fragrance stays identical, which is the whole point: a buyer who came to the launch and returns to book six weeks later walks into the same building they remember. Write the fragrance name and the settings on the handover sheet so nobody changes them when the site manager changes.
Tip: one 400ml fill usually carries launch night and the first weeks of the gallery, up to about 75 days of running.
The Vaayu app holds 1h, 4h, 8h and 24h schedules with adjustable intensity, so switching from event mode to gallery mode takes a minute.

The SOSA principle
Developers budget lakhs for the launch stage and nothing for the air in the room, then wonder why the venue still smells like a venue.
The fragrance is the only part of a launch that keeps working after the marquee comes down.
What goes where on launch day
Here is the whole setup as a table. Read it as a shopping list: one line per separately moving body of air, one machine against each.

On the fragrance itself, this is the one decision that outlives the evening, so it gets its own page: read the signature fragrance guide for a luxury property launch before you order, because a profile that reads beautifully in an empty hall at four in the afternoon can turn heavy once four hundred warm bodies and a catering counter arrive. If you are working out how far in advance to place the order and run the test, the launch scenting timeline counts the days back from launch morning for you. And for the ongoing gallery plan that this setup hands over to, the pillar guide on planning scenting for a luxury real estate sales gallery covers the sizing maths in full.
The whole launch setup is two or three machines
SOSA Vaayu ₹11,999 covers up to 1000m³, about 2,000-3,000 sq ft. Send the venue plan and the run of show and we will build the setup before you raise the purchase order.
Nobody at your launch will say the room smelled wonderful. They will say the project felt finished, and that is the sentence you were paying for.

The SOSA project launch specification
Two machines, one decision, and both of them keep earning after launch night. The Vaayu handles a foyer, a normal-height launch floor and the sample flat; the Angaan takes over when the launch hall is a single banquet-scale volume. Both are waterless, so there is no damp and no residue on hired finishes, and both are made in India. A portion of every order supports girl-child education through Nanhi Kali.

A quick word on choosing: the count comes from air volume, not from the number of zones on the event plan, and the machines are an asset rather than an event consumable. One honest note - fragrance works alongside ventilation and cleaning at a venue, cannot cover fresh paint, adhesive or damp, and SOSA makes no claim that scent influences a purchase decision. The quickest way to get it right is a free scenting plan from your venue drawings.

A note from Sonal
A launch is the only evening a developer gets to introduce a building that does not exist yet. Everything in the room is doing the same job - the light, the model, the champagne, the way the invitation felt in someone's hand. Smell is the one channel nobody has specified, which is why so many launches smell of carpet, cabling, cold air and catering. That is not a disaster. It is just a missed line on the finishing schedule.
My advice is to keep the setup embarrassingly small. Two or three Vaayu machines, one fragrance, one schedule. Each is rated to 1000m³, roughly 2,000 to 3,000 sq ft, and each weighs 0.9kg, so the same units you plug in at the venue on Friday are running in the sales gallery on Monday. If the launch hall is genuinely banquet scale, one Angaan does what five small machines cannot, because it works with the room's airflow instead of against it.
And the honest part, which I say to every developer before they order: fragrance cannot cover a construction smell, and it will not sell a flat. Fresh paint, adhesive and new flooring need curing, ventilation and time, and scent layered on top gives you both smells at once. We make no claim that fragrance influences a purchase decision - it makes a space feel finished and considered, which is a real thing but a modest one. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
What does a complete fragrance setup for a project launch cost?
For most launches, between one and three machines. A SOSA Vaayu is Rs 11,999 and covers up to 1000 cubic metres, about 2,000 to 3,000 sq ft, so a foyer plus a launch floor is roughly Rs 24,000 of equipment plus fragrance. A banquet-scale hall of 8,000 to 10,000 sq ft is one SOSA Angaan at Rs 25,999 instead of several smaller units. The machines are not an event consumable, so the cost is spread over the life of the project, not the evening.
Should we hire scent machines for the launch instead of buying them?
Buy them. The launch is one evening but the equipment is not one-evening equipment. The morning after, it moves into the sales gallery and the sample flat and runs there for the life of the project. A 400ml Vaayu tank lasts up to 75 days, so a single fill usually covers launch night and the first weeks of the gallery.
How many machines does a launch venue need?
Count the separately moving bodies of air, not the zones on the event plan. Foyer, launch floor and sample flat are usually three, each up to 1000 cubic metres on a SOSA Vaayu at Rs 11,999. If the hall is a single volume of 8,000 to 10,000 sq ft, that is one SOSA Angaan at Rs 25,999 rather than five small machines competing with each other.
Our launch venue is hired and we cannot drill or duct anything. Does that work?
Yes. The Vaayu is 0.9kg on a 5W supply and stands freestanding on a plinth or console, so it needs a plug point and nothing else. It is waterless, so there is no risk of damp or residue on a hired carpet or a rented stage, and the key-lock stops anyone changing settings during a public event. The Angaan also runs standalone on a wall mount when a marquee has no ducting at all.
Will fragrance make people buy at the launch?
No, and we do not claim it does. Scent makes a space feel finished, consistent and considered, which is worth doing on the one evening you cannot repeat. It works alongside ventilation and cleaning, not instead of them, and it will not cover the smell of fresh paint or new adhesive in a venue that has just been fitted out.
