Source cleanroom equipment with an AI agent.

Where to source cleanroom equipment: FlowMarket is a B2B sourcing network powered by an AI agent. You describe the requirement — the ISO 14644 class or GMP grade and whether it applies at rest or in operation, room size and layout, air changes and filtration, pressure cascade, temperature and humidity, monitoring, and the qualification documentation you need — and the AI agent matches you with verified cleanroom manufacturers and installers, then requests specifications, prices and lead times from every match at once. Getting matched is free for buyers.

A cleanroom is not bought as a room but as a controlled condition, and the classification alone does not describe it. ISO 7 held while nobody is working is a fraction of the cost of ISO 7 held with eight people assembling product inside it.

That distinction — the occupancy state the class must be met in — is the single most consequential line in a cleanroom enquiry, and the one most often left out.

What you can source

Rooms and enclosures

Modular cleanrooms built from wall panels and a suspended ceiling grid, either freestanding inside an existing building or fitted into a shell. Softwall enclosures cost far less and suit lower classifications or temporary needs. Both are sized by classification, footprint and the air handling that has to sit behind them, which is usually the larger part of the budget.

Filtration and airflow

Filter fan units mount in the ceiling grid and deliver filtered air locally, which makes them the flexible way to reach a classification without a large central plant. HEPA and ULPA filters are classified to EN 1822 — H13 and H14 are the common cleanroom grades — and laminar flow benches provide a small zone of unidirectional clean air for critical handling within a lower-class room.

Access control and monitoring

• Air showers — remove particles from personnel before they enter the classified area.
• Pass-throughs and material locks — move material in without breaking the pressure cascade.
• Cleanroom furniture and garments — low-shedding, cleanable, specified to the class.
• Particle counters and monitoring — continuous or periodic measurement with alarming and data retention.

What to specify when sourcing

These details decide both the design and the price:

• Classification — ISO 14644 class or GMP grade, and whether it applies at rest or in operation.
• Industry — pharmaceutical, medical device, semiconductor, optics or food; the rules differ substantially.
• Size and layout — floor area, ceiling height, and the airlocks and gowning areas around it.
• Occupancy and process — how many people, what they do, and what the process itself emits.
• Air changes and filtration — required air change rate and filter class, or leave it to the supplier to derive.
• Pressure cascade — the differential to be held between rooms and to the outside.
• Temperature and humidity — setpoints and tolerances, which often drive the air handling more than the class.
• Monitoring — particle counting, differential pressure, temperature and humidity, with alarms and records.
• Qualification — the documentation you require: design, installation and operational qualification.
• Site and schedule — existing building constraints, services available, and the date it must be operational.

The class is not the specification, and validation is not a line item

Two things routinely turn a cleanroom project into an argument. The first is treating the ISO class as the whole requirement. A classification is a particle count, and reaching it depends on how much clean air you push through the space, how much contamination is generated inside, and whether the count must hold while people work. In operation is far harder than at rest, because people are the dominant particle source — so a room that certifies beautifully on handover can fail once production starts if the enquiry never said it had to. State the occupancy state, the number of people and what the process emits, and let the supplier derive the air change rate rather than specifying one you read somewhere. Alongside it, name the pressure cascade: a classified room stays clean partly because it is held at a higher pressure than what surrounds it, and the cascade through airlocks and adjacent spaces has to be designed as a system, not per room. The second is qualification. In a regulated environment — pharmaceutical or medical device in particular — the documented evidence that the room does what it claims is not paperwork attached to the end of the job; it is a substantial part of the cost and the schedule, and it can approach the price of the physical equipment. Design, installation and operational qualification each produce deliverables that must be agreed in advance, and a supplier who has priced the hardware while assuming you will handle qualification yourself will look dramatically cheaper than one who included it. Ask every offer to state exactly which qualification documents are inside the price, and compare on that basis — otherwise you are not comparing the same project.
