Prefabricated Hardwall Clean Room CNC ISO 7 Class 10,000 Cleanrooms

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

Cleanrooms By anlaitech produces fully functional ISO 7 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 7 clean rooms makes them easy to expand, reconfigure, or relocate as your cleanroom needs evolve.

ISO 7 Cleanroom Standards

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. ISO class 7 clean rooms were previously defined under US Federal Standard 209E but are now defined under ISO 14644-1, however, both are still regularly used as reference points.

US Federal Standard 209E: denotes the number of particles (≥0.5 µm or larger) per cubic foot (f³) of air.
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 7 Cleanroom Protective Requirements

Class 10,000 cleanrooms require workers to wear fewer protective garments than cleanrooms with a lower classification but still require the use of cleanroom clothing such as face masks, hair and beard covers, and lab coats or other frocks to cover street clothing. In some ISO7 cleanrooms, coveralls and gloves may also be required. Cleanroom clothing is made from nonwoven fabrics to prevent contamination from shedding material fibers. Gloves are sterile and made from latex, nitrile or other synthetic materials.

Depending on industry and application requirements, other precautionary measures may be taken to control particle count in an ISO 7 cleanroom environment. Sticky mats are often placed outside of cleanroom entrances to remove dirt and other contaminants from shoes. Pass-thru cabinets fitted with filtration systems may also be used to safely transfer products while limiting the number of people entering and exiting the room.

Cleanroom requirements vary widely based on industry standards and the type of processes being performed. Always consult with a cleanroom professional for assistance in selecting the design and classification that are best suited for your application. Common ISO 7 clean room requirements include:

Product pass throughs
HEPA fan filters
Heat welded vinyl or epoxy floors
Gowning atrium
Air locks
Air conditioners
Entrance and exit sticky mats
Sealed lighting
Bunny suit, booties, and hood requirements
Stainless steel bench and hands free sink
