A cleanroom is a controlled environment that filters pollutants like dust, airborne microbes, and aerosol particles to provide the cleanest area possible. Most controlled environments protect the production of products like electronic devices, pharmaceuticals, and medical equipment. Cleanrooms are classified into different classes depending on the number of particles allowed in the air per cubic meter. They also control variables like temperature, airflow, and humidity.
How does it work?
Essentially, cleanrooms work to remove pollutants, particles, and contaminants from outside ambient air. Outside air passes through a filter system. The filters (HEPA or ULPA) then clean and decontaminate this outside air according to their specifications. The filter then introduces the processed air into the controlled environment. Inside, positive pressure creates air flow, flushing out contamination generated by internal activities. The contaminated air is either returned to the ambient air or recirculated to the filters, where the process restarts. There are many different types of cleanrooms. The right type for you will depend on many factors, including size, application, and the type of room you need to convert.
Who needs a cleanroom?
A company may need a cleanroom for a wide variety of reasons. As a general rule, if you’re manufacturing something that is easily affected by contaminants or particles in the air, you’ll likely need a cleanroom. If you’re unsure, or if you’d like an estimate, call the experts at Angstrom. Here are a few common reasons you might need a cleanroom, and some common industries that regularly use cleanrooms:
