What is a Modular Cleanroom?

A modular cleanroom is a type of controlled environment designed to provide filtered, extremely clean air within a space to minimize the possibility of airborne contaminants. Modular cleanrooms are typically used in sensitive manufacturing environments where even tiny particles can adversely impact the final product. Modular cleanrooms are typically employed in industries like pharmaceuticals, electronics, semiconductor, biotechnology, and aerospace.

The term “modular” in modular cleanrooms refers to the construction method employed. Rather than being constructed entirely on site, modular cleanrooms are prefabricated in sections or panels, which are then assembled on site. These panel sections are manufactured to size based upon the approved set of plans from the customer, and are interlocked together to form the walls of the modular cleanroom. Then, based on the customer’s unique design requirements, a ceiling and a top deck are added to seal the cleanroom from the outside space. The decking may be capable of supporting equipment based on the particular application and requirements of the modular cleanroom.

Prefabrication and assembly on-site using similar or identical wall sections allows for quick and easy modification, reconfiguration, expansion, or even disassembly and relocation of the modular cleanroom. The modular construction of cleanrooms and prefabrication off-site typically results in lower cost, faster deployment, and less disruption to the customer’s ongoing activities. The panel sections that comprise the modular cleanroom are available in a range of materials, thicknesses, core materials, color options, insulative and load-bearing capabilities, and can be pre-wired and plumbed with electrical, data, water, and other process consumables.

Benefits of Modular Cleanroom Construction

  1. Modular Construction: Modular cleanrooms are assembled on site using prefabricated sections and panels. This approach ensures a rigid free-standing structure, design flexibility, rapid installation, ease of expansion and modification, and easy disassembly for relocation.
  2. Flexibility: Because modular cleanrooms are assembled from prefabricated panels, sections can be reconfigured, added, or removed to expand size and accommodate changes in production capacity. Because of their flexible nature, modular cleanrooms can be easily partitioned and have filters added or removed to provide classification upgrades or create areas of differing classifications. Modular cleanrooms can also be disassembled and relocated as required. Available in a wide range of finishes and core materials, modular cleanrooms are a versatile solution capable of meeting the requirements of any industry.
  3. Cost Efficiency: Combining the mass-production of prefabricated panels with strict environmental control, modular cleanrooms are an ideal and cost effective solution for medium-sized projects without sacrificing quality, reliability, or performance.
  4. Rapid Deployment: Since all sections and panels are prefabricated off site, on site assembly time is dramatically reduced, resulting in an environment with strict control, tight tolerances, and quick installation in as little as 4 weeks.
  5. Regulatory Compliance: Our modular cleanroom systems are capable of meeting the strictest regulatory requirements, including USP, cGMP, BSL, and others in classifications ranging from ISO 3 to ISO 8 (Class 1 to Class 100,000).
  6. Minimal Disruption: Our interlocking modular cleanroom systems are prefabricated off site to minimize construction debris, noise, and contamination typically associated with traditionally constructed facilities.
