ISO 8 Cleanrooms

ISO 8 cleanrooms, also known as Class 100,000 cleanrooms, can be modular or soft-walled and have a maximum particle count of 100,000 particles (≥0.5 um) per cubic foot of interior air. They are required to have HEPA filtration coverage over 4-5% of the area and provide a minimum of 20 air exchanges per hour with air flow rates of 4-8 CFM per square foot.

Cleanrooms By United produces technologically advanced ISO 8 cleanrooms that meet all required specifications and requirements. We provide the layout, square footage, and features that your project specifications require. The custom, flexible, modular construction of our ISO 8 clean rooms makes them easy to expand, reconfigure, or relocate as your cleanroom needs evolve.

ISO 8, Class 100,000 Cleanroom Standards

Cleanroom classifications range from ISO 1 to ISO 9, with ISO 9 being the “dirtiest” and ISO 1 being the “cleanest.” These classifications are assigned based on the maximum allowable concentration of particles per cubic foot or meter of air. Contamination levels in ISO 8/Class 100,000 cleanrooms are measured by the concentration of particles in a cubic foot or meter of air. These levels are measured in microns and defined by the following standards:

ISO 14644-1: replaced federal standard 209E in 2001 but is still used as a reference. It denotes the number of particles (≥0.1µm to ≥5µm or more) per cubic meter (m³) of air.

ISO 8 Cleanroom Particle Specifications

ISO 8 clean rooms do not require certain particle sizes to be tested, either because concentration levels are too high or low to be tested, but it cannot be zero. For ISO Class 8, particles smaller than 0.5 µm aren’t considered. The concentration of particles that are ≥0.5 µm should be below 3,520,000.

ISO 8 Cleanroom Protective Requirements

There are different ISO 8 cleanroom designs, including modular cleanrooms and soft-sided cleanrooms. A modular cleanroom has hard-sided walls that provide complete floor-to-ceiling protection for a higher level of cleanliness. They are used for permanent and semi-permanent installations and can be configured to any size. Softwall cleanrooms are constructed of soft panels or strips and do not touch the floor. They are designed for portability and more temporary installations and are commonly used as a “spot clean” enclosure within an already controlled environment.

In addition to structure, there are other important considerations for usability and to ensure effective control contaminant levels. Incorporating air showers, pass-through chambers and other additional cleanroom accessories into the cleanroom design may be required to help prevent contamination from entering the cleanroom environment. Lighting, filtration and temperature control are also extremely important.

Cleanroom design considerations and standard requirements vary depending on the industry and application. In general, primary considerations for designing a Class 100,000 cleanroom include:

Hard-walled Modular Cleanroom Advantages

Due to their ease of maintenance and simple installation methods, hard-walled modular cleanrooms are increasing in popularity in numerous industries across the globe. Since they can be installed quickly and easily and can be modified or even relocated with minimal expense and downtime. Many prefabricated modular cleanrooms are almost 100% reusable. Some additional benefits of a hard-walled modular cleanroom include:

Flexible & Affordable Modular Cleanroom Systems

Since they are constructed of hard or soft panels with a hard ceiling, modular cleanroom systems are highly configurable. Soft panel cleanrooms have walls made from clear PVC and one small opening for entering and exiting the area. Hard panel systems consist of prefabricated panels that join to create a square or rectangular room. Hard-walled cleanrooms are fully enclosed and can be fitted with doors, windows, and transfer hatches, just like a permanent cleanroom.

Some of the advantages modular cleanroom systems provide over permanent clean rooms include:

What Cleanroom Classification do you need?

A typical cleanroom is designed to keep outside contaminants and particles at a minimum based on the ISO clean room standards. Once fully built and operational, an isolated cleanroom is free from outside particles and contamination. However, the two things that can introduce particles and contamination into your cleanroom are people and processes.

Classification for cleanrooms ranges from ISO 1 to ISO 9, with ISO 9 being the “dirtiest” and ISO 1 being the “cleanest.” These classifications are assigned based on the maximum allowable concentration of particles per cubic foot or meter of air. The lower the ISO class the more stringent the requirements for keeping particles and contamination to the acceptable levels of the room class.

As an example, ISO 8 cleanrooms, also known as Class 100,000 cleanrooms, can be modular or soft-walled and have a maximum particle count of 100,000 particles (≥0.5 um) per cubic foot of interior air. They are required to have HEPA filtration coverage over 4-5% of the area and provide a minimum of 20 air exchanges per hour with air flow rates of 4-8 CFM per square foot.
