What is a cleanroom?
Summary
A cleanroom is a controlled environment in which pollutants such as dust, microorganisms in the air, and aerosol particles are filtered out to provide the cleanest possible area. Most cleanrooms are used to manufacture products such as electronics, pharmaceutical products, and medical equipment. Cleanrooms can be divided into different pollution levels according to the number of particles allowed per cubic meter. The cleanroom also controls variables such as temperature, airflow, and humidity.
How does a cleanroom work?
A cleanroom provides a controlled isolation environment for handling pollution-sensitive substances or protecting the external environment from harmful substances in the controlled area.
The density of sub-micron and larger particle pollutants in the cleanroom air is strictly controlled within the limit by forcing clean, filtered air into the cleanroom.
Pollution and contamination are constantly generated by personnel, processes, facilities, and equipment, and must be continuously removed from the cleanroom. The allowable degree of contamination is determined by the specifications of the operations performed.
Industries that use cleanrooms
Many products, processes, and procedures require space for cleaning and disinfection during the manufacturing process.
This ensures that everything manufactured is free from contamination, and the process is safe and accurate to produce high-quality products. If the conditions are not optimal, rework may be required, which will cost the manufacturer time and money. The industries that utilize cleanrooms are:
- Electronic Part Production
Anyone in the IT industry knows that certain factors can cause product damage, including temperature, humidity, and static electricity.
In a cleanroom, these factors will directly affect the manufacture of various electronic parts. Various cleanroom products are required in the electronic part production industry, such as anti-static work clothes and lab coats, anti-static wipes, ESD (electrostatic discharge) cleaning products, ESD floor, and workbench mats.
- Biotechnology
In the biotechnology industry, there are various markets, such as medical research to develop new drugs, agricultural research to develop better food, environmental research to further the understanding of the protection of the earth, or industrial research and testing for chemical production.
Processing in these areas requires sensitive liquids, organic substances, and living cells in almost pollution-free spaces. Any contamination may cause inaccurate test results. The biotechnology industry needs sterile cotton swabs, wipes, aprons, masks, and gloves.
- Life Sciences
Like biotechnology, life sciences include chemistry and pharmaceutical biology at the cellular level, including plant, animal, or human cells.
The life science industry stores and manipulates cells in liquids and organic substances that are extremely sensitive to pollution. In the pharmaceutical industry, scientists and researchers can also deal with chemicals and compounds. Cleanrooms in the life science industry require products like pre-soaked wet wipes and dry wipes, mops, disinfectants, cotton swabs, and sterile products.
- Food Manufacturing
Fairly new use of cleanrooms is in the food industry. The production and manufacture of food is a highly regulated process because millions of people suffer from allergies and prevent contamination of processed foods (such as meat and cheese processing).
Cleanrooms require high hygiene standards to prevent the growth and growth of bacteria, fungi, or molds. To create an ideal environment for a cleanroom, humidity, moisture, temperature, wind speed, and air pressure must be optimal. Cleanrooms in the food industry require gloves, masks, goggles, work clothes, and overshoes.
- Automotive
The automotive industry is generally related to workshops and large manufacturing factories.
However, today's vehicles are composed of many sensitive circuits and computer components, which can be damaged by static electricity, humidity, temperature, or air pressure. Like the production of electronic parts, clean rooms in the automotive industry also require cleanroom products, such as anti-static work clothes and lab coats, wipes, and ESD cleaning products.
