How do I forecast fragrance oil for a Vaayu programme? From the tank. Each SOSA Vaayu (₹11,999) holds 400ml and a fill lasts up to about 75 days depending on intensity and run hours, which is roughly 5.3ml a day or 480ml per machine over a 90-day quarter. Twelve machines across six sites is therefore about 5.8 litres a quarter at moderate settings, rising towards 9.6 litres where sites run at a higher intensity step or longer hours.
What settings should every Vaayu in the programme run? One intensity step and one timer block, written down and key-locked. Most sales offices use the 8h block starting about 45 minutes before opening, with sample flats one intensity step lower on the same fragrance and the same block. The SOSA Vaayu (₹11,999) offers 1h, 4h, 8h and 24h timers with adjustable intensity, and the key-lock is what keeps the setting where the sheet put it.

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 onboard button control, 1h/4h/8h/24h timers, adjustable intensity, operation under 38dB, freestanding or wall and HVAC mounting, auto-stop and key-lock for public spaces, 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, connecting to the building's HVAC or running 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.
This is the whole programme in one place: how many machines per site, what every machine is set to, how the refills run, what to order each quarter and what to check four times a year. Every number in it comes from the Vaayu's own specification, so you can rebuild it for your own portfolio.
Quick answers — read this first
What is in a SOSA Vaayu multi-site scenting programme? Five things: the machine count per site, the settings sheet, the monthly refill round, the quarterly stock forecast and the quarterly review. The standard unit is the SOSA Vaayu (₹11,999), rated to 1000m³ or about 2,000-3,000 sq ft, so a standard site is two machines - one in the sales office and one in the sample flat. A double-height volume takes a SOSA Angaan (₹25,999) on the HVAC instead.How do I forecast fragrance oil for a Vaayu programme? From the tank. Each SOSA Vaayu (₹11,999) holds 400ml and a fill lasts up to about 75 days depending on intensity and run hours, which is roughly 5.3ml a day or 480ml per machine over a 90-day quarter.

The short answer
Short answer: the programme is five lines - one SOSA Vaayu (₹11,999) per 1000m³ so about two per site, one intensity step and one timer block key-locked across the portfolio, a monthly top-up round logged in millilitres, a quarterly forecast of roughly 480ml per machine at moderate settings, and a quarterly review - with the SOSA Angaan (₹25,999) as the one documented exception for a double-height volume.
The pick: the SOSA Vaayu (₹11,999) as the programme unit at every site, with the SOSA Angaan (₹25,999) written in once for a volume that is double height or 8,000-10,000 sq ft.

Straight answer
What does a complete SOSA Vaayu multi-site programme look like?
Five lines, and then the working. Count: one SOSA Vaayu (₹11,999) per 1000m³ of connected air, which is about 2,000-3,000 sq ft, so a standard site is two machines - one in the sales office, one in the sample flat - and a six-site portfolio is twelve, plus roughly one spare per ten in service. Settings: one intensity step and one timer block for the whole portfolio, typically the 8h block starting about 45 minutes before opening, with sample flats one step lower on the same fragrance, then the key-lock engaged at every machine. Refills: one top-up round a month on a fixed day, every tank filled to full, millilitres logged per machine. Stock: the Vaayu tank is 400ml and a fill lasts up to about 75 days depending on intensity and run hours, which is roughly 5.3ml a day, about 160ml a month and about 480ml per machine per quarter; twelve machines is therefore about 5.8 litres a quarter at moderate settings, and closer to 9.6 litres where sites run a higher step over long days, so hold a quarter centrally with one spare fill per site. Review: twenty minutes each quarter on consumption, settings drift, site feedback and any launches coming up that will need an extra litre. The one documented exception is the SOSA Angaan (₹25,999) where a single volume is double height or 8,000-10,000 sq ft; it runs programmable schedules on the HVAC, holds 800ml and carries the same fragrance as the rest of that site. Everything here is honest about its limits: fragrance works alongside ventilation and cleaning, and we make no claim it influences a purchase decision. A free multi-site scenting plan will fill this sheet in for your portfolio, and a portion of every order supports girl-child education through Nanhi Kali.
Count, settings, refills, stock, review. One Vaayu per 1000m³, one settings sheet key-locked, one monthly round, about 480ml per machine per quarter, one quarterly review.
Every number in this programme comes from one machine. The SOSA Vaayu is rated to 1000m³ (about 2,000-3,000 sq ft), holds 400ml with a fill lasting up to about 75 days depending on intensity and run hours, runs under 38dB, offers 1h/4h/8h/24h timers and adjustable intensity, and locks with a key-lock for public spaces.

The machines in the programme
The programme contains two machines and no more, which is deliberate: a specification that names one standard unit and one exception is one that a site team can follow without a phone call. Both pictures link to the live product page.
The programme unit - two per standard site

The three pages that make up the programme document
The programme document is three pages: what you own, how it is set, and what it consumes. Here is what belongs on each.
1
Page one - what you own
The register: sites, volumes, machines, spares
One row per connected volume across the portfolio, with length, width, height, the resulting cubic metres and the machine count. One Vaayu per 1000m³, rounding down and checking the far corner. Add the mounting position for each unit - on the air path near the entrance airflow or beside the air-conditioning return - and mark the one or two volumes that take an Angaan instead. Finish with the spares line: about one per ten machines in service, held centrally with the settings sheet taped to the box.
Tip: record ceiling height in the register - it is the number that makes two similar-looking sites differ.
The Vaayu is 1000m³, 0.9kg and mounts freestanding, on a wall or to HVAC, so the register can specify placement precisely.
See SOSA Vaayu →
2
Page two - how it is set
The settings sheet: fragrance, step, block, start time, lock
One fragrance for the portfolio. One intensity step for sales offices, one step lower for sample flats. One timer block - usually 8h - with the start time written relative to opening rather than as a clock time, so sites with different hours stay in step. Mounting position, and the instruction to re-engage the key-lock after any authorised change. Name the one person who may authorise a change at all. This page is short on purpose: a settings sheet that runs to three pages is a settings sheet nobody applies.
The Angaan runs programmable schedules on the HVAC and joins the same fragrance and the same quarterly audit.
See SOSA Angaan →
3
Page three - what it consumes
The refill log and the quarterly forecast
The arithmetic is fixed by the tank. 400ml, up to about 75 days, so roughly 5.3ml a day, 160ml a month and 480ml a quarter per machine at moderate intensity and typical run hours. Twelve machines is about 5.8 litres a quarter. Be explicit that the 75-day figure is an upper end: at a higher intensity step over 12 to 14 hour days a tank can go in around 45 days, which takes the same twelve machines to roughly 9.6 litres. Log millilitres monthly, order quarterly against the log, and add about a litre against any site with a launch in the window.
Tip: replace my figures with your log after two rounds - your numbers already include your run hours.
A Vaayu holds 400ml and is waterless, so what you pour in each month is exactly what the site used.
See SOSA Vaayu →
The SOSA principle
A programme you can print on three pages is a programme a site team will actually follow. Everything longer than that becomes a folder nobody opens after the first month.
Count, settings, consumption. If a page is not one of those three, it does not belong in the document.
The programme on one sheet
Here is the whole programme as a single reference sheet. Every figure is from the machines' own specifications, so you can check it against the product pages before you commit.

This guide is the summary; each line has its own working. The count is expanded in how many scent machines a multi-project developer needs, the settings sheet in standardising scent machine settings across multiple sales offices, and the ordering rhythm in planning monthly scent machine refills across multiple project sites. The one decision this sheet does not make for you is the fragrance strategy, which is argued through in one signature scent versus a different fragrance for each project. For a single flagship, use the sales gallery scenting plan instead.

The SOSA Vaayu programme specification
The programme runs on one machine, with one documented exception. The Vaayu is the unit at every site; the Angaan appears once, where a volume is genuinely double height or 8,000-10,000 sq ft. Both are waterless, so there is no damp, no heat and no residue on scale models, veneers or fabric, and both are made in India. A portion of every order supports girl-child education through Nanhi Kali.

A quick word on using this guide: every figure here comes from the machines' own specifications, and the one that moves most is the fill life. 75 days is an upper end that assumes moderate intensity and typical run hours; a higher step over long days can empty the same 400ml tank in around 45. Forecast against the harder number and let your own refill log correct it. One honest note - fragrance works alongside ventilation and cleaning and cannot cover fresh paint, adhesive or damp, and we make no claim that it influences a purchase decision. We will complete the sheet with you on a free multi-site scenting plan.

A note from Sonal
This is the document I wish every developer had before the first machine arrived. Not a brochure - a working sheet with your site count on it, the settings written in numbers, and the arithmetic that turns a tank size into a purchase order.
It fits on three pages. Page one is what you own: one Vaayu per 1000m³ of connected air, which is about two per standard site, plus a spare per ten. Page two is how it is set: one fragrance, one intensity step, the 8h block starting 45 minutes before opening, flats one step lower, key-lock engaged. Page three is what it consumes: 400ml per tank, up to about 75 days per fill, so roughly 480ml per machine per quarter at moderate settings and about 5.8 litres for twelve machines - closer to 9.6 if your sites run hard. The one exception written into the whole thing is an Angaan at a genuinely double-height centre.
The honest part, which belongs in the programme document itself: this delivers consistency and perceived quality across your sites, and that is the entire claim. I make no claim that fragrance influences a purchase decision. It works alongside ventilation and cleaning rather than instead of them, and it cannot cover fresh paint, adhesive or damp - commission a site only after it has been properly aired. SOSA's hotel-inspired fragrances are our own original interpretations; we are an independent Indian brand and are not affiliated with any hotel. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
What is included in a SOSA Vaayu multi-site scenting programme?
Five lines: the machine count per site, the settings sheet, the monthly refill round, the quarterly stock forecast and the quarterly review. The standard unit is the SOSA Vaayu (Rs 11,999) at 1000 cubic metres coverage, about 2,000 to 3,000 sq ft, so a standard site is two machines. The one documented exception is the SOSA Angaan (Rs 25,999) on the HVAC where a volume is double height or 8,000 to 10,000 sq ft.
How much oil does a twelve-machine portfolio use per quarter?
About 5.8 litres at moderate settings. Each 400ml tank lasts up to about 75 days depending on intensity and run hours, which is roughly 5.3ml a day and about 480ml per machine over a 90-day quarter. If sites run at a higher intensity step or 12 to 14 hour days, a tank can empty in around 45 days instead, which takes the same twelve machines to roughly 9.6 litres a quarter.
What settings does the programme specify?
One fragrance for the portfolio, one intensity step for sales offices with sample flats one step lower, one timer block - usually the 8h option - starting about 45 minutes before opening, and the key-lock engaged afterwards. Write the start time relative to opening rather than as a clock time so sites with different hours stay in step, and name the one person who may authorise a change.
How many spare machines should the programme hold?
About one per ten units in service, held centrally rather than at a site, with the settings sheet taped to the box. Because every site runs the same SOSA Vaayu, one spare covers the whole portfolio and can be swapped in the same day, which is far cheaper than a flagship sales office running unscented while a unit is away.
Does this programme claim to improve sales at our sites?
No. It delivers consistency of experience and steadier perceived quality across your projects, and that is the whole claim. Fragrance works alongside ventilation and cleaning rather than instead of them, it cannot cover fresh paint, adhesive or damp, and we make no claim that it influences a purchase decision.
