A cleanroom is an environment where airborn particulates are controlled through an exchange of highly filtered air using a high efficiency particulate air (HEPA) filtering system, and through minimization of activities that generate particles.Pharmacy Cleanroom
A class 100 cleanroom maintains less than one hundred particles larger than 0.5 microns in each cubic foot of air space. In addition to particle control, the cleanroom is temperature and humidity controlled to 70F, 45% RH.Microelectronics Cleanroom
By comparison your typical office space has between 500,000 and 1 million particles per cubic foot. Cleanrooms come in different classes from class 100 to 100,000.Food Germ-Free Cleanroom
ISO 4 or Class 10 cleanrooms are an ultra-clean stringently controlled cleanrooms utilized primarily for nanotechnology, semiconductor, and control zones within biotechnology and pharmaceutical applications for filling lines or other critical points.Hospital Cleanroom
Class 100 cleanrooms are the third highest classification in Federal Standard 209 standards. In order to meet regulations, a Class 100 standard clean room must never exceed 100 particles per cubic foot (the particles being 0.5 microns or larger).Printing Packaging Cleanroom
In cleanrooms, particulate concentration changes over time — from the construction and installation of equipment to its operational status. ISO delineates three cleanroom classification standards: as-built, at-rest and operational. Read more about cleanrooms and gowning room design considerations/recommendations. As instruments and equipment are introduced and particulates rise, an "as-built" cleanroom becomes an "at-rest" cleanroom. When people are added to the matrix, particulate levels rise still further in the "operational" cleanroom.Blow Molding Film Cleanroom
ISO 5 (Class 100 Cleanroom) and cleaner facilities rely on unidirectional, or laminar, airflow. Laminar airflow means that filtered air is uniformly supplied in one direction (at a fixed velocity) in parallel streams, usually vertically. Air is generally recirculated from the base of the walls back up to the filtering system.
