American Cleanroom Systems manufactures modular cleanroom components at its California manufacturing facility, including:
American Cleanroom Systems uses only Made in America cleanroom equipment in our cleanrooms.
American Cleanroom Systems manufactures in house all major cleanroom components at its California facility.
Factory fabrication allows panels, doors, windows, and openings to be produced to project-specific dimensions.
Electrical, data, return-air, and pass-through openings can be prepared before installation, reducing cutting and fabrication work at the job site.
Design, manufacturing, installation, and testing can be handled by the same organization.

A: Modular cleanroom is manufactured using prefabricated wall, ceiling, door, and other cleanroom components that are fabricated to the dimensions of the project and then assembled on-site. At American Cleanroom Systems, modular cleanroom manufacturing includes in-house panel laminating, fabrication, cutting, and assembly. Electrical and HVAC-related openings can also be prepared during manufacturing, reducing the amount of cutting and modification required during installation.
A: American Cleanroom Systems manufactures modular and softwall cleanroom systems in the USA at its facility in Rancho Santa Margarita, California. The facility includes manufacturing operations, a design center, and a demonstration cleanroom, and customers can arrange a factory visit. 99% of modular cleanroom is made in USA – only significant exception is LED flat panel lights which are manufactured in Mexico.
A: Yes. American Cleanroom Systems modular cleanrooms are all manufactured to project-specific dimensions and configurations. Wall panels can be cut to required sizes, with factory-prepared openings for items such as return-air grilles, pass-throughs, make-up-air grilles, electrical outlets, light switches, and data connections. Custom cleanroom doors and windows are also manufactured at the company's California facility.
A: Cleanroom wall panels can be manufactured using different surface skins and core materials depending on the application. Available wall skins include melamine, FRP, painted aluminum, stainless steel, and vinyl gypsum board. Core options include honeycomb, aluminum honeycomb, polystyrene, urethane, and gypsum board. The appropriate combination depends on the cleanroom's application, performance requirements, and budget.
A: Factory manufacturing allows components to be fabricated and prepared before they arrive at the project site. For example, wall panels are cut to their required dimensions and prepared for air grilles, pass-throughs, electrical connections, and data ports. This eliminates field cutting and fabrication, which can help shorten installation time and create a cleaner installation process.
A: After the cleanroom is completed and operating, American Cleanroom Systems performs an "as-built" particle test on each room. Testing is performed according to ISO 14644-1, and the company's laser particle counters are calibrated annually using NIST-traceable standards.
A: Yes. American Cleanroom Systems states maintains a written quality program and is Avetta certified. We have supplied our manufacturing quality plan to government and pharmaceutical organizations with demanding quality requirements.
A: Manufacturing quality is controlled through in-house fabrication, assembly, equipment maintenance, and testing. American Cleanroom Systems performs manufacturing at its California facility and conducts monthly, quarterly, and annual preventive maintenance on manufacturing equipment.
A: Manufacturing and installation time varies according to cleanroom size, classification, configuration, equipment, and project requirements. Because many components are fabricated and prepared in the factory before installation, factory manufacturing can reduce the amount of fabrication required in the field. At American Cleanroom Systems upon approval of shop drawings manufacturing can take between 2 to 12 weeks.
A: Yes. American Cleanroom Systems manufactures cleanrooms for applications including pharmaceutical manufacturing, medical device manufacturing, electronics, aerospace, research, and other controlled-environment applications.
