When Does a Diagnostic Centre Need Multiple SOSA Vaayu Scenting Zones?

When it contains more than one separate body of air that customers occupy. That is the entire rule, and everything else on this page is a way of applying it. Three arrangements qualify. A different floor, because a staircase and a lift lobby are not a shared volume and the upper waiting area does its own thing whatever you install downstairs. A wing on its own air handling, because separate supply and return means the two halves of a building do not exchange air in any useful quantity. And a room behind a door that stays closed, which in this vertical is nearly always an executive lounge. Those three are volumes. What is not a volume: a large floor area, a second waiting bay off the same concourse, a department boundary, a change of flooring, a half-height screen, or the fact that one end of the hall reads weaker than the other. Now the mechanism, because the rule is only convincing once you know why the alternative fails. A single source in a connected space produces one gradient - strongest near the unit, fading with distance and with whatever the air conditioning is doing. Add a second source in the same air and you have two overlapping gradients whose meeting point moves through the day as the doors cycle and the room fills. Nobody set the level in that overlap, and it is the part patients notice. So the second unit does not add coverage; it adds an argument, and the usual correction of turning both down leaves a less even room at more than twice the price. The arithmetic then follows the count. Size each genuine volume separately, using square feet × ceiling height in metres × 0.0929. A single-floor centre with 1,800 sq ft of public area at 3.2m holds 1,800 × 3.2 × 0.0929, about 535 cubic metres: one volume, one machine, well inside a SOSA Vaayu's 1000m³ rating. A two-floor centre with 1,400 sq ft of public area on each floor at 3.1m holds about 403 cubic metres per floor: two volumes, two machines, and each one sized against its own number rather than against the total. A centre with a 900 sq ft waiting area at 3.2m and a 300 sq ft lounge at 3m holds about 268 cubic metres and 84: two volumes, and the second takes a ₹749 reed rather than a second machine, running the same fragrance a touch fuller. Here is the concession, and it is the honest heart of the page: most centres that ask me this have one volume. A reception, a waiting area open to it, a corridor that buffers, and clinical rooms that get nothing. One machine, correctly placed, is the whole specification, and the second unit they were about to buy would have made the result worse rather than better. Fragrance here is an ambience decision like lighting, seating or signage, it works alongside your ventilation and cleaning rather than instead of them, SOSA products are not medical devices, we make no claim that scenting affects how a centre performs commercially, and the clinician's judgement overrides any scenting plan, including mine.
