Medical Device Cleanroom UK | ISO 7 & 8, ISO 13485-Ready | PackSealer
Medical device cleanroom UK
A medical device cleanroom is a controlled environment that holds airborne particles to an ISO 14644-1 class and supports the contamination control your ISO 13485 quality system demands. Most device manufacturing runs at ISO 8, with ISO 7 for sterile or critical assembly and an ISO 8 gowning lobby in front. PackSealer supplies Monmouth Scientific modular cleanrooms, designed and built in the UK, with kits from £17,560 ex VAT or facility-scale builds scoped to your floor plan. Monmouth built for ADDEV Parafix a 500m² medical device facility; the case study is below.
What a medical device cleanroom needs
Two standards sit behind every medical device cleanroom, and they do different jobs. ISO 14644-1 governs the room: the particle class, the air changes, the validation. ISO 13485 governs your quality system: the controls, the records, the process validation that show a regulator your devices are made under control. The cleanroom is the physical part of that quality system, built and validated so your ISO 13485 evidence holds up.
For most device work the production area runs at ISO 8 (Class 100,000), with an ISO 8 gowning lobby in front and an ISO 7 zone where assembly is sterile or particle-critical. That layered design, gowning into ISO 8 into ISO 7, with a pressure cascade holding clean spaces positive to dirty ones, is the standard medical device cleanroom configuration.
Monmouth Scientific modular cleanrooms deliver that layered envelope as a single system: HEPA-filtered ceiling, vinyl-clad or coated panels with coved edges for cleaning, gasketed sliding doors, airlocks, and an integrated monitoring panel. We will tell you which classes your process actually calls for before you spend on the build.
Case study: a 500m² medical device facility for ADDEV Parafix
ADDEV Parafix in Lancing, West Sussex converts medical-grade adhesives, technical films, and membranes into ready-to-use components under ISO 13485:2016. Growth meant they needed a larger controlled environment built around their converting machinery, not a generic box dropped into a corner.
Monmouth Scientific designed and delivered a 26m by 26m facility of roughly 500m²: 15 operational zones with controlled transitions between ISO 7 and ISO 8, entrance and exit airlocks, gowning, production cells, material transfer bays, and packing. CAMT2000 HEPA modules, a Visionaire real-time monitoring system, cleanroom flooring, and concealed services trunking throughout. It was laid out around high-precision die-cutting, multi-layer lamination, and slitting held to ±0.25mm.
It is the largest modular cleanroom Monmouth has delivered. Richard Sincock, General Manager at ADDEV Parafix, put it plainly: "From the early design discussions through to installation, Monmouth understood exactly what we were trying to achieve. What stands out most is the scalability. We are not constrained by this environment, it has been designed to grow with us."
Which ISO class does your device work need?
The class is a process decision driven by your ISO 13485 risk assessment, and the build cost follows it. Device work usually maps to a class like this. Tell us the process and we will confirm the class with you.
| Device process | Typical ISO class | EU GMP grade | Why |
|---|---|---|---|
| Sterile device assembly, implants, single-use surgical | ISO 7 | Grade B/C | Particle-critical; tighter cap protects the sterile path |
| IVD, diagnostics, controlled fluid handling | ISO 7 or ISO 8 | Grade C/D | Process risk decides; often ISO 7 core, ISO 8 support |
| General device assembly, packaging, adhesive converting | ISO 8 | Grade C/D | Class 100,000 holds the count for non-sterile build |
| Gowning, material staging, kitting, support areas | ISO 8 | Grade D | Buffer and transition into the production zone |
Most device manufacturers land on a layered build: an ISO 8 production area, an ISO 7 zone for the critical step, and an ISO 8 gowning lobby. If your assembly is not sterile-critical, an ISO 8 envelope holds the count at a fraction of the build and running cost of ISO 7. The ISO 8 cleanroom page covers the entry class in detail.
Validation, ISO 13485 evidence and lifetime support
An auditor will not take the room on trust. Monmouth provide Installation Qualification and Operational Qualification documentation, particle count testing to ISO 14644-1, and HEPA integrity testing, so the build slots straight into your ISO 13485 design and process validation file as evidence. The cleanroom holds the ISO 14644-1 classification; the ISO 13485 certification stays with you and your quality system.
Filters need replacing on a schedule, gaskets need inspection, and monitoring instruments need calibration. We hold spare HEPA modules, gasket kits, and door seals in UK stock for every Monmouth build we sell, so a filter swap ships in days. Recurring revalidation visits keep your particle data current for the next audit, and run £400 to £795 per visit.
Monmouth Cleanroom Kits for device manufacturing
Facility-scale device manufacturing cleanrooms
Multi-zone production facilities like the ADDEV Parafix build: mixed ISO 7 and ISO 8 areas, gowning and airlock sequences, material transfer bays, integrated HVAC, and real-time particle monitoring, all laid out around your converting and assembly machinery. Engineered to your floor plan, validated to ISO 14644-1, IQ/OQ documentation included. Lead times typically 8 to 14 weeks depending on scope. Send us your scope and we will quote within a working week.

Common questions about medical device cleanrooms
It depends on the process and your ISO 13485 risk assessment. Most device manufacturing runs at ISO 8 (Class 100,000) for general assembly and packaging, with an ISO 7 zone where assembly is sterile or particle-critical and an ISO 8 gowning lobby in front. Sterile devices and implants usually need ISO 7; IVD and diagnostics sit at ISO 7 or 8 depending on the step. Tell us the process and we will confirm the class.
There is no separate "ISO 13485 cleanroom" standard. ISO 13485 is the quality management system standard for medical device manufacturers; the cleanroom is the controlled environment that supports it. The room itself is classified and validated to ISO 14644-1 (the cleanroom standard), and that validation evidence forms part of your ISO 13485 quality file. So an "ISO 13485 cleanroom" is a cleanroom built and documented to support an ISO 13485 quality system.
No. ISO 13485 certification belongs to your organisation and its quality system, not to the room. What the cleanroom needs is classification and validation to ISO 14644-1, plus IQ/OQ documentation an auditor can review. We supply that documentation with the build so it drops into your ISO 13485 evidence. The certification stays yours.
The right class is the loosest one your process can hold. ISO 7 allows ten times fewer particles than ISO 8 and needs more air changes, so it costs more to build and run. Reserve it for sterile or particle-critical assembly. ISO 8 holds the count for general device assembly and packaging at a lower cost. Most device facilities use both: an ISO 7 core for the critical step inside an ISO 8 production area.
A Monmouth Cleanroom Kit starts at £17,560 ex VAT for 12m² and runs to £24,800 ex VAT for 25m². The kit envelope is the same across ISO classes, so the price holds for an ISO 8 or ISO 7 target. Multi-zone facility builds are quoted to scope, typically £40,000 to £500,000, with large facilities like the 500m² ADDEV Parafix build above that range. Validation visits run £400 to £795 per visit.
A standard Monmouth Cleanroom Kit ships in 4 to 6 weeks from order and goes up in 1 to 2 days of self-assembly, or 3 to 5 days if our crew installs it. Multi-zone facility builds run 8 to 14 weeks from order to validated handover depending on scope. The cleanroom installation page sets out the full survey-to-handover path.
Yes. Monmouth built for ADDEV Parafix a 500m² facility with 15 zones, controlled ISO 7 and ISO 8 transitions, gowning, airlocks, material transfer bays, and packing, laid out around their converting machinery. It is Monmouth's largest modular cleanroom to date. Facility builds are designed to your floor plan and your process flow, then validated to ISO 14644-1 with full IQ/OQ documentation.
No. PackSealer supplies Monmouth cleanrooms for purchase only. For short-term project work or interim capacity, ask about clean tents and flexible clean canopies as a lower-cost option. For permanent device manufacturing capacity, a Cleanroom Kit or scoped build is the right route and typically pays back faster than rental over a 12-month horizon.
