Cleanroom class depends on product risk, intended use and customer or regulatory requirements. Many device plants use ISO 7 or ISO 8, and critical stations such as implant packaging may use ISO 5. Your risk assessment and the standards for your device type decide the final class. The table gives common references.
| Process area | Typical class | Typical materials from us |
|---|---|---|
| Implant or sterile-critical final packaging | ISO 5 station in ISO 7 room | Laminar Air Flow, flush panels, interlocked doors |
| Catheter and delivery system assembly | ISO 7 | Panels, HEPA Supply Boxes, Air Shower |
| Syringe, tubing and disposable assembly | ISO 7 or ISO 8 | Panels, flush doors, Pass Box |
| Injection molding of components | ISO 8 around molding machines | Economical panels, wide doors |
| Final packaging and sealing | ISO 7 or ISO 8 | Panels, windows, Pass Box |
| IVD reagent and kit assembly | ISO 7 or ISO 8, humidity control | Moisture-stable panels |
| Medical electronics assembly | ISO 7 or ISO 8, anti-static finishes | Anti-static panels, doors |
Design considerations:
- Bioburden control: surfaces and layout should limit microorganisms as well as particles.
- Material flow: keep raw parts, work in process and finished packaged goods apart.
- Humidity: some materials and adhesives need controlled humidity, commonly 40–60 % RH.
- Equipment size: molding machines and packaging lines need wide doors and strong floors.
We customize dimensions, colors and door options for each plant.
Please also tell us about your sterilization method and packaging materials, because some processes, such as ethylene oxide or radiation, have separate area requirements before and after sterilization, and these affect layout, doors and pass-through points.
Cross-Border Delivery and Localized Construction Support
Medical device companies frequently expand quickly, add new lines for new products or move production to new countries. We therefore plan delivery around machine installation, validation and product launch dates, and we make sure the cleanroom shipment arrives at the right time.
- Layout confirmation: we review the process flow, equipment sizes and cleanliness classes by room.
- Flat-pack shipping: panels and profiles are packed flat, and mixed loads reduce freight cost.
- Documents: packing list, commercial invoice and certificate of origin, with FOB, CFR or CIF terms.
- Phased shipments: large plants can be delivered in stages, matched to construction.
- Installation help: manuals, video guidance or an on-site engineer.
Local construction: a trained local contractor can usually install modular device cleanrooms efficiently. For production plants, the most important coordination points are machine access routes, floor loading, utility penetrations and ceiling loads. Molding and extrusion machines can be heavy, and compressed air, vacuum and cooling water lines often need openings in walls and ceilings that must be sealed carefully.
Local building, fire and electrical rules apply, and your engineer or contractor remains responsible for approvals.
For device plants with several production lines, we suggest agreeing a clear phase plan, so Line 1 can start validation while Line 2 is still being built. We prepare drawings and shipments for each phase and mark the interfaces between old and new areas, so later expansion does not interfere with running production.
Staged delivery also eases storage and customs processes.
Quality Control and Certification
Device makers are audited through their quality system, process validation and product records. Building materials are not certified as "medical device grade", and we do not claim otherwise. We provide consistent products and documents that make your audits and validation easier.
| Control step | Inspection | Why it matters |
|---|---|---|
| Incoming materials | Sheet, face, core, profiles, gaskets, glass | Known quality |
| Panel production | Dimensions, flatness, bonding, edge sealing | Tight, flush joints |
| Surface inspection | Scratches, bubbles, color, cleanability | Low particle shedding |
| Door and window | Gasket contact, hardware, interlock function | Pressure stability |
| Equipment check | Pass Box, Air Shower and fan function | Ready for installation |
| Packing | Count, labels, condition | Complete delivery |
Documents available: material specifications, factory inspection records, filter data and, where available, reports on fire or surface performance. These can support your facility validation file.
After installation, a qualified third party should measure particle counts, airflow, pressure and filter integrity, and ongoing monitoring should follow your quality procedures. If a customer audit or a regulator requires a specific document, tell us early, and we will confirm what we can supply. Supplier audits of our factory are welcome.
Device customers often receive supplier audits from their own customers, such as large brand owners or hospital groups. We support these by answering questionnaires, providing material data and showing our production steps. Factory visits and video tours are available, and batch records can be shared where appropriate.
We also encourage you to ask your validation team which documents they will need, so we can confirm early what we can supply and what must come from other parties, such as the HVAC contractor or the testing agency.
After-Sales Service and Response Capability
Medical device production lines run to tight delivery schedules, and a damaged door or a leaking joint can affect cleanliness and output. We support customers with quick answers and matching spare parts, using the drawings and records stored for each project.
- Fast communication: technical questions answered in English by email, phone or messaging.
- Remote diagnosis: photos and short videos of doors, gaskets, windows or joints help us assess problems.
- Spare parts: gaskets, hinges, closers, handles, door leaves, windows, lights and HEPA Filters.
- Line changes: doors can be widened, openings added or rooms extended with updated drawings.
- Engineer visits: by arrangement.
Typical wear points in device plants:
| Location | Typical issue | Suggested action |
|---|---|---|
| Door edges and wall bases | Trolley impact | Add protective rails, repair or replace panel |
| Door gaskets | Compression wear | Replace gasket |
| Window frames | Sealant aging | Re-seal frame |
| Wall openings for utilities | Gaps after machine changes | Reseal with suitable material |
Small repairs made early prevent bigger cleanliness problems later. Please keep a log of changes, since auditors may ask for it.
Production lines for medical devices change often, with new tools, new products and new packaging formats. Our after-sales team therefore helps not only with repairs but also with modifications, such as adding a pass-through window, widening a door or opening a wall for a new machine.
When you plan such a change, send us the present drawing and a sketch of the new layout. We will review it, advise on sealing and structure and prepare the required parts. Keeping spare panels, gaskets and sealant on site makes small changes faster.
Our engineers can also join a video call with your maintenance team.
Commercial Terms, Warranty and Lifecycle Cost
Medical device companies often have several product lines, each with its own volume and class. A flexible and modular envelope lets you match room class and size to each line and change them as sales grow. This is usually more economical than building a single high-class space for everything.
| Item | Our approach |
|---|---|
| Quotation | Itemized by room and component, with drawings |
| Trade terms | FOB, CFR or CIF, defined in the quotation |
| Payment | Commonly a deposit with balance before shipment or against documents; final terms in the contract |
| Warranty | Defined by component group in the contract |
| Lead time | Given after drawing confirmation |
| Customization | Size, thickness, color, door width, window options |
Ways to control long-term cost:
- Match class to risk: use ISO 5 only for critical stations and ISO 7 or ISO 8 elsewhere.
- Protect high-wear areas: rails and bumpers extend panel life.
- Improve airtightness: lowers fan and cooling energy.
- Plan for growth: modular layouts allow new lines without demolition.
Production machines, HVAC, utilities, monitoring, validation and permits are outside our supply. Warranty exclusions are stated clearly in the contract.
It helps to compare quotations by including the cost of future changes. A system that allows walls and doors to be moved with little waste may cost slightly more at the start but saves considerable money when product lines change.
We provide itemized quotations and can show how different panel cores, face materials and door types affect price, durability and cleaning effort, so you can choose what fits each room.

Medical Device Manufacturing Cleanroom FAQ
Q1. Which cleanroom class do medical devices need?
It depends on the device and its risk. ISO 7 and ISO 8 are common, with ISO 5 for critical stations. Your risk assessment and customer or regulatory requirements decide.
Q2. Do I need a cleanroom for all devices?
Not always. Many non-sterile devices need only clean, controlled production areas, while sterile or implantable devices usually need classified rooms.
Q3. Are your panels medical grade?
No building product is certified that way. Our panels offer smooth, sealed, cleanable surfaces with records that support your validation.
Q4. How does ISO 13485 affect the cleanroom?
ISO 13485 requires controlled work environments suited to the product. Your quality system defines the requirements, and the cleanroom is one way to meet them.
Q5. Can you supply molding-area cleanrooms?
Yes. We can design rooms with wide doors and strong panels for molding machines, with air supply and extraction planned with your HVAC engineer.
Q6. Can the plant be expanded later?
Yes. Modular panels let you add rooms and lines as production grows.
Q7. How do I get a quotation?
Send your product type, target class, layout and destination country.
Q8. Can you build cleanrooms for medical electronics?
Yes. We can supply anti-static finishes and humidity-stable panels for electronic device assembly.
Q9. Do I need an air shower?
Not always. Many device plants use gowning rooms and airlocks, while air showers help at high-traffic points or for extra particle removal.
Q10. Can you supply sample panels?
Yes, samples can be sent for testing with your own cleaning agents.
