Automotive cleanrooms are used for the design, production, assembly, and testing of automotive parts and components. Since many of these products will be operated by regular people, they protect not only the future owners of the vehicle, but also other drivers on the road. The stakes for functionality and safety are high, and so are the regulations for manufacturing, assembling, and testing automotive parts and products.

The automotive industry requires cleanrooms for many applications at various levels of the supply chain. As vehicles are more advanced, manufacturing is less about just fitting the pieces together and is instead continually becoming more complex. Components are often interconnected through calibrated sensors, an intelligent computer system, and unique safety features. During the manufacturing process, sensitive elements can be compromised by changes in temperature, humidity, and pressure, and are especially vulnerable to contamination and defects due to static electricity. A controlled environment is required to ensure that all vehicles and components are assembled correctly to prevent the risk of product malfunction or failure, and to guarantee customer safety.


Angstrom cleanrooms can be free-standing or make use of existing walls and structures in your facility. They are made to be top-quality, durable, and high-performing. Our modular cleanrooms for the automotive industry are available as HardWall or RigidWall cleanrooms.

Automotive Cleanroom systems

An automotive cleanroom is necessary to control the manufacturing environment to ensure product consistency and consumer safety, especially in those applications where the presence of contaminants could be a risk to an employee, buyer, or other drivers. In a controlled cleanroom space, environmental factors are monitored to limit airborne and surface contamination to an acceptable degree, as outlined by the cleanroom classification.

These factors are controlled by your cleanroom’s systems, specifically through HEPA filtration and your cleanroom HVAC. Other features included in your cleanroom design help to minimize threats of contamination, limit safety risks, or just make your work easier.

Automotive cleanroom applications include automotive research and development, component manufacturing, assembly, and packaging. These applications make sure all automotive parts are produced, cleaned, and packaged safely.

Automotive manufacturing is more than the image of an assembly line with parts being attached until a new, shiny vehicle appears at the other end of the facility. Today’s vehicles are more complex than ever before, infused with computerized components that allow them to achieve better things like more reliability, fuel efficiency, and advanced sensor technology. These components require protection during manufacturing so they can live up to their promises. That’s where the controlled environment of the cleanroom comes in. Cleanrooms can provide control over humidity, particles, contamination, pressure, and temperature to ensure consistency and cleanliness in your products.

In addition to manufacturing and assembly, the testing of automotive components and products is commonly conducted within a cleanroom, and is of vital importance to consumer safety. Testing determines the functionality and safety of new products, finds defects that can occur during production, and makes sure all automotive parts are the best possible quality before they are available to consumers.

Automotive testing is responsible for preventing mass defects and saving millions of lives — as well as millions of dollars in product recalls. Cleanrooms are used for testing applications to focus the study on desired variables. These tests can include the CASS test for corrosion resistance as well as testing the performance of glass coatings, electrical components, and vehicle safety features.

When it comes to cleanroom design, rely on the experts at Angstrom Technology. Based on your specifications and unique application, we can design the ideal cleanroom for you. Our team can build versatile layout options that will encourage productivity and accessibility. With a layout in place, we can use computational fluid dynamics to create a digital model of your cleanroom space to find the best airflow pattern for your cleanroom, reducing the strain on your cleanroom’s HVAC system and changing the air more effectively. 

Angstrom Technology can assist in construction of your cleanroom, adaptation of your cleanroom site, even retrofit the cleanroom build to existing infrastructure. Our modular cleanrooms are pre-manufactured so when they arrive at your site, they can be assembled quickly and efficiently. We’ll provide straightforward instructions so you can set up your cleanroom yourself, or have our crew install it for you. We can also install industry-specific equipment so your cleanroom is up and running as soon as possible.

Cleanrooms are controlled environments that establish a high level of air quality to limit contamination through air and surface particles. Automotive cleanrooms are controlled by classifications that determine the allowed number of particles per cubic meter of a certain size. Particle size and count matter because even the smallest particles can interfere with automotive manufacturing processes and lead to serious defects, damage, or bodily harm.

The primary authority for cleanroom classifications is the International Standards Organization (ISO), which organizes cleanrooms in ISO 14644-1 into 9 classes by their level of cleanliness, as defined by particle size and number, hourly air changes or airflow velocity, and percentage of ceiling coverage of fan filter units. Although different applications in the automotive industry will need to comply with different classification standards depending on the threat of contamination and worker safety requirements, most automotive cleanrooms fall within ISO 14644-1 Classes 5-8.

ISO Requirements - Sensitive Materials

ISO requirements can change significantly with each class type. For example an ISO Class 5 cleanroom is only allowed a maximum particle count of 3,520 at 0.5 microns per cubic meter compared to the 352,000 microns of an ISO Class 7 or the 3,520,000 of an ISO Class 8 cleanroom. Certain manufacturing processes, such as those working with electronics and microchips, will require a greater level of process control and may come with more stringent ISO standards. 

There are also industry-specific requirements for automotive cleanrooms that work with sensitive materials or processes. Two examples of these are:

  • ISO 18413 – For applications working with hydraulic fluid components, this standards document specifies cleanliness and outlines how to conduct inspections. 
  • ISO 16232 – This document relates to the cleanliness of components and systems used specifically for road vehicles, as well as how to test and verify cleanliness.
ISO Requirements - Quality Materials

For automotive cleanrooms, industry-specific standards can include performance tests of paints and finishes like CASS, as well as quality assurance testing. The CASS (Copper Accelerated Salt Spray) test occurs in some applications to determine corrosion resistance of aluminum alloys or chromium plating. It’s often used during research and development, but also has a place in evaluating manufacturing or product efficacy. The CASS test must be conducted within a controlled environment, ideally an automotive cleanroom.

To monitor and manage quality, most manufacturers of automotive components are required to meet these standards: 

  • ISO 9001 Establishes a customer-focused quality assurance system within a facility to ensure accountability in management and develop a process for continual improvement.
  • ISO/TS 16949 Outlines the setup of a quality management system for the entire supply chain of automotive development — including design, production, installation, and service — for safety, consistency, and reliability of all products and processes.
Environment Requirements

To meet the strict safety regulations in the automotive industry, a cleanroom environment is necessary to maintain the required standards of quality. At its most basic function, a modular automotive cleanroom is designed to limit the introduction of contaminants into the cleanroom, limit exposure to contaminants while in the cleanroom, and continually remove contaminating particles from the air — but it does so much more than that

The environmental control of temperature, humidity, pressure, and static are essential for the safe and effective production of automotive parts. An automotive cleanroom is also equipped with the extra features and systems your unique application needs to be successful. If your project requirements change, your cleanroom should be able to adapt to meet new classifications and reach new standards for optimal control. This can only be achieved in an Angstrom Technology modular automotive cleanroom.
