The ISO 7 classification cleanroom is designed to maintain the highest levels of air cleanliness. The hard-sided walls and HEPA filtration systems work together to ensure that the air inside the cleanroom is free from contaminants, with a maximum of 10,000 particles per cubic foot. This makes it the ideal environment for a wide range of applications, from pharmaceutical manufacturing to electronics assembly.
An ISO 7 cleanroom classification is an expansive classification since it’s a cleanroom that can be used in a variety of industries and application types. An ISO 7 Cleanroom provides a clean environment with air quality control for laboratories, production facilities, bio-exclusion zones, research and development labs, medical device packaging, and pharmaceutical packaging.
The airflow for an ISO 7 cleanroom design follows a mixed airflow pattern.
Air changes range from 30 to 70 per hour of HEPA-filtered air and less than or equal to 5µ(microns).
High-Efficiency Penetration Air (HEPA) filtration efficiency is 99.99% at 0.3µm(microns).
Filtration and particle measurements in an ISO 7 cleanroom prohibit a particle from being greater than 0.5µ but less than 5.0µ.
Gown or airlock room for ISO 7 classification cleanrooms prevents loss of particle control and air quality in the environment. Since an ISO 7 air change per hour is between 30 and 70, the gown room will have HEPA filters to recover the air quality before entering the cleanroom.
