What is a modular cGMP cleanroom?

A modular cGMP cleanroom is a permanently installed, off-site engineered and fabricated facility that arrives on-site as a fully integrated, process-ready environment. Unlike traditional construction, where a cleanroom is built inside an existing shell building, Germfree's modular cleanrooms are freestanding structures — the building and the cleanroom are one and the same. All critical systems, including HVAC, electrical, lighting, utilities, and environmental monitoring infrastructure, are integrated during fabrication before the unit ever reaches the site. This approach compresses project timelines significantly compared to conventional construction, reduces on-site disruption, and ensures that system integration and quality control happen in a controlled manufacturing environment rather than in the field. The result is a facility that is ready to begin commissioning, qualification, and validation (CQV) activities much sooner than a traditionally built cleanroom.

What industries and processes are these cleanrooms built for?

Germfree modular cGMP cleanrooms are purpose-built for the biopharma industry, where the regulatory demands, environmental controls, and process integrity requirements are among the most rigorous in any sector. Applications span a wide range of advanced therapeutic and manufacturing workflows, including cell therapy, gene therapy, viral vector production, mRNA manufacturing, monoclonal antibody (mAb) production, and sterile fill-finish operations. The facilities are also well-suited for radiopharmaceutical preparation, plasmid manufacturing, and CRISPR-related research workflows. Because each facility is engineered around the specific process it will house, the room layout, airflow design, material flow, and utility infrastructure are configured to support the actual workflow — not adapted from a generic template.

What cleanroom grades and rooms can be included?

Modular cGMP cleanrooms can be configured to include a full range of EU GMP and ISO-equivalent cleanroom grades depending on the processes being performed. Typical configurations incorporate Grade D (ISO 8) support spaces, Grade C (ISO 7) processing areas, and Grade B (ISO 5 background) suites for aseptic operations. For the most critical aseptic processes, Grade A unidirectional airflow zones can be integrated within Grade B environments using isolators or restricted access barrier systems (RABS). Beyond the core processing rooms, configurations commonly include material airlocks (MALs), personnel airlocks (PALs), anterooms, gowning and degowning rooms, and equipment or parts wash areas. The specific room sequence and adjacency planning is driven by the process flow, contamination control strategy, and regulatory framework applicable to the product being manufactured.

How are HVAC and environmental controls handled?

The facility is equipped with a fully integrated HVAC system designed and built to maintain the precise temperature, humidity, air change rates, and differential pressure parameters required for cGMP manufacturing. Pressure cascades between rooms are engineered to prevent cross-contamination and are monitored continuously through an integrated environmental monitoring system. The HVAC design accounts for the specific heat and humidity loads introduced by process equipment, personnel, and the compounding environment itself. Systems are also compatible with bio-decontamination protocols — including vaporized hydrogen peroxide (VHP) — for facilities where periodic room decontamination is required, such as those used in viral vector or cell therapy manufacturing. All HVAC components are specified and installed to support the qualification and validation activities required for regulatory submission, including IQ, OQ, and PQ protocols.

Can modular cGMP cleanrooms be relocated or adapted later?

Yes. One of the defining advantages of a modular facility is its inherent flexibility over the lifecycle of the project. Because the structure is freestanding and self-contained, it can be integrated with an existing building, connected to another modular unit to expand capacity, or relocated to a different site entirely as operational needs evolve. This makes modular cleanrooms particularly well-suited for organizations that are scaling up, entering new markets, or operating in an environment where long-term real estate commitments are uncertain. Facilities can also be adapted internally — with changes to room layouts, equipment configurations, or utility infrastructure — more readily than a traditionally constructed cleanroom embedded within a permanent building. This lifecycle flexibility means the initial capital investment continues to deliver value even as programs, processes, or business strategies change.
