Setting the Industry Standard

Allied Cleanrooms has been building modular clean rooms and environmental enclosures for over 20 years. Based out of California and Tennessee, our facilities provide coverage for coast-to-coast shipments in the United States and abroad.

We specialize in Class 10 to Class 100,000 (ISO 4 – ISO 8) cleanrooms that are used for some of the following activities: environmental test chambers, pharmaceutical storage rooms, temperature controlled rooms, bio-safety laboratories, pharmaceutical research laboratories, stem cell research laboratories, server control rooms, organic chemistry laboratories, laser rooms, microbiology laboratories, dry rooms and more.

We offer a complete turnkey solution that begins with building to your exact specifications and seeing your project through until completion. Our non-invasive modular construction process involves the manufacturing of your clean room in a factory, resulting in short lead times and a minimal amount of on-site construction contamination. Our modular clean rooms are reusable, reconfigurable and environmentally friendly which will minimize your carbon footprint.

Controlled Environment to Meet the Latest Industry Standards

While the concept of a controlled environment may be the same, Allied Cleanrooms understands that products, research and industry standards can differ in numerous aspects. That’s why we are fully capable of creating custom modular clean rooms that meet your specific industry’s needs.

Aerospace – We understand that the aerospace industry may need a controlled contamination area for composites and other compounds, which is why we can construct custom modular hardwall clean rooms that fulfill specifications and/or ASTM International standards.

Pharmaceuticals – If you are researching compounds for forthcoming products or require a clean room for a specific point in the manufacturing process, Allied Cleanrooms is here to help. We specialize in high-risk local zones, which mean we can assure that you will have a safe environment for stopper bowls, vials, filling zones and aseptic connections with homogenous air speed that meets or exceeds the Food and Drug Administration’s (FDA) regulations. This includes Current Good Manufacturing Practice Regulations (CGMP) and Drug Applications.

Nutraceuticals – While the industry standards for nutraceuticals are different compared to pharmaceuticals, they must still adhere to General Manufacturing Practices (GMP) set in place by the FDA as well as the Dietary Supplement and Education Act of 1994. Instead of waiting for the guidelines to come, set precedence in your industry by using modular clean rooms today!

Medical Devices – Medical devices are a fundamental aspect to the healthcare industry and with high industry standards, you can achieve FDA-approved modular clean rooms from us. Ensure that your medical devices are of the highest quality with air cleanliness assurance from Allied Cleanrooms.
