Class 10000 Cleanrooms

What is a Class 10000 (ISO 7) Cleanroom?

An ISO 7 cleanroom, or Class 10000 cleanroom, is a hard-sided, modular wall facility that utilizes HEPA filtration systems to maintain air cleanliness levels with a maximum of 10,000 particles (≥0.5µm) per cubic foot. Class 10000 cleanroom filtration systems must provide filter coverage of 15-25% and a maximum of 60 air changes per hour. The standard air flow rate for an ISO 7 cleanroom filtration system is 9-16 CFM per square foot.

Cleanrooms by United produces a variety of cleanroom solutions for contaminant-free applications, including fully functional ISO 7 cleanrooms to meet requirements. We provide the layout, square footage, and features your project specifications need. Custom, flexible, modular cleanroom construction makes our Class 10000 cleanrooms easy to expand, reconfigure, and relocate as your needs evolve.

What are the Guidelines for ISO 7 Cleanroom Requirements?

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. The number of air changes per hour drives the main difference between cleanroom classes, where ISO 7 cleanrooms have 30-60 air changes per hour. They were previously defined under US Federal Standard 209E but are now defined under ISO 14664-1:

  • US Federal Standard 209E: denotes the number of particles (≥0.5 µm or larger) per cubic foot (f³) of air
  • ISO 14644-1: replaced standard 209E in 2001 but is still used as a reference, which denotes the number of particles (≥0.1µm to ≥5µm or more) per cubic meter (m³) of air.

ISO 7 Cleanroom Requirements

Cleanrooms by United is your partner in cleanroom design and production, offering complete design services or engineering guidance for a cost-effective system that meets your requirements. Factory-engineered and made to your specifications for temperature, humidity, differential pressure, lighting, and noise levels, your cleanroom can be tailored to your exact needs, including solutions for types of doors, windows, wall panels, flooring, and much more.

We manufacture modular cleanroom designs with components that can be reconfigured to meet standards for ISO class 8 to ISO class 5 solutions. These prefabricated, panelized wall systems offer easy relocation, expansion, and modification with minimal expense for an almost entirely reusable, sustainable option that will not disrupt operations with traditional construction. Our case studies offer examples of how much customization can be achieved in your ISO 7 cleanroom.

Air Quality, Airflow, and Temperature Control

To meet the desired particle count of ISO 7 cleanrooms, our designs utilize high-efficiency air filtration and environmental control systems. HEPA and ULPA filters effectively remove particles to contribute to the controlled environment specifications for your operations. At the same time, positive air pressure is maintained within the cleanroom to prevent the introduction of contaminants into the environment, creating a barrier to push particles out rather than draw them in. The design of your ISO 7 cleanroom should also include temperature and humidity control systems to maintain a consistent environment for sensitive processes.

Contaminant Control Requirements

Various precautions may be taken to maintain the permissible maximum particle count of 352,000 per cubic meter, depending on the industry and application requirements. As requirements are based on the industry standards and processes being performed, it is essential to consult a cleanroom professional for assistance to select design requirements that are best suited to your application, including:

  • Pass-thru windows, cabinets, and chambers
  • HEPA fan filters
  • Heat-welded vinyl or epoxy floors
  • Gowning atrium
  • Airlocks and conditioners
  • Entrance and exit sticky mats
  • Sealed lighting
  • Stainless steel benches
  • Hands-free sinks

Protective Gear for Personnel

Class 10000 cleanrooms require personnel to wear fewer protective garments than cleanrooms with a lower classification, but they still benefit from solutions that cover street clothing and prevent contamination. Cleanroom clothing is made from nonwoven fabrics to avoid contamination from shedding material fibers, including synthetic gloves for increased sterilization and sticky mats to remove dirt and other contaminants from shoes. ISO 7 cleanroom requirements for personnel include:

  • Face masks, hair, and beard covers
  • Lab coats, coveralls, or frocks
  • Bunny suits, booties, and hoods

Advantages of Class 10000 Cleanrooms

Modular cleanrooms offer a range of benefits to spatial constraints in facilities or warehouses, making them highly popular for contaminant-free operations across various industries. They are easy to maintain and install, and once fully built, they offer an isolated, modular solution that is free from outside particles. Easily modified or relocated with minimal expense or downtime, prefabricated modular designs are nearly 100% reusable and provide operational advantages, such as:

  • More cost-effective than traditional construction
  • Fast installation in days, not weeks
  • Prefabricated and custom modular solutions
  • Pre-wired with UL-classified raceways
  • Options for energy efficiency
  • Customizations to lower contamination
