Pharmaceutical and medical device manufacturing has higher requirements than any other industry.
The right cleanroom is crucial for quality, safety, and approval. Here you can find out what it takes to build a solution that meets both ISO and GMP requirements—and is ready for future production.
Pharmaceutical and medical device manufacturing requires total control of air, materials, and processes. It is not just a matter of meeting standards—it is about ensuring patient safety. To succeed, you need a well-designed cleanroom solution tailored to your product, risk level, and production flow.
A cleanroom for pharmaceutical and medical device manufacturing must be more than just clean. It must be built to withstand the demands of flexibility, traceability, and sustainability—while facilitating validation, documentation, and future expansion.
What are the requirements for pharmaceutical and medical device manufacturing?
Manufacturing in the pharmaceutical and medical technology industries is governed by strictly regulated standards such as ISO 14644-1 and EU-GMP. Classifications such as ISO 7 or ISO 8 are common, but for particularly sensitive products, the requirements can be as high as ISO 5.
In the pharmaceutical industry, GMP grades (A–D) are often used, where, for example, filling zones require a Grade A environment. For medical device manufacturing, the requirements are also governed by quality management systems in accordance with ISO 13485, which means clear procedures for both processes and documentation.
Cleanroom classes and standards – what do they mean in practice?
The cleanroom class determines how many particles are allowed in the air and how the air flow should be designed. In an ISO 7 environment, a maximum of 352,000 particles of 0.5 µm per cubic meter of air are allowed, while an ISO 5 cleanroom allows only 3,520.
For pharmaceutical and medical device manufacturing, classification affects everything from ventilation systems to the choice of filters, pressure zones, and material surfaces. By determining early on which class your production needs, you can avoid unnecessary renovations and costly validations.
Material selection and modular solutions
In pharmaceutical and medical device manufacturing, the choice of materials is crucial. Surfaces must be smooth, impervious, and easy to clean, while also being able to withstand frequent disinfection. Aluminum profiles with recessed painted panels in steel or stainless steel are common, as are block walls—both for hygiene and durability.
Octanorm Cleanroom system solutions enable the construction of flexible cleanrooms that can be adapted and expanded as needed. Doors, ceilings, airlocks, and windows can be combined in a modular fashion and integrated into existing buildings without compromising on airtightness or flow control.
Five important questions to consider before your next cleanroom project
A holistic approach for future-proof manufacturing
Pharmaceutical and medical device manufacturing is changing rapidly. New materials, shorter development cycles, and increased regulatory requirements place higher demands on cleanrooms that can evolve over time.
By choosing a modular solution with a holistic perspective—where walls, ceilings, and airlocks are integrated—you get a cleanroom that not only meets today's requirements but also those of tomorrow. It's about creating security at every stage—from idea to production.
When you build clean rooms for pharmaceutical and medical device manufacturing, it's basically about patient safety. A well-planned solution reduces the risk of operational disruptions, lowers energy costs, and meets regulatory requirements from the start.
The right cleanroom is not a cost – it is a long-term investment in quality, efficiency, and trust.
Frequently Asked Questions
What cleanroom class is required for pharmaceutical and medical device manufacturing?
It depends on the product and process. Simpler assembly can be done in ISO 8, while sterile
products require ISO 5 or GMP Grade A.
What standards apply to pharmaceutical and medical device manufacturing?
The most common are ISO 14644-1 for cleanrooms and ISO 13485 for medical device quality, as well as
EU GMP directives for pharmaceuticals.
What materials are recommended in cleanrooms for pharmaceutical and medical device manufacturing?
Smooth, chemical-resistant, seamless, and sealed surfaces such as painted aluminum, steel, or stainless steel
that are easy to clean and disinfect.
How often should a cleanroom be validated?
Depending on classification and activity, but as a rule of thumb
A/B zones → 6-month intervals.
C/D zones → annual intervals.
ISO 5 or better 6-month intervals.
ISO 6-8 annual intervals
Extra re-validation in the event of changes, deviations or major maintenance (filter replacement, renovation,
process changes, etc.) Cleanrooms for pharmaceutical and medical device manufacturing must be checked
immediately.
