Satisfied Customers: Read why customers chose American Cleanroom Systems and why they come back.
A: A cleanroom (or clean room) is a room that has HEPA filtration to remove particles from the air. Cleanrooms are used for manufacturing where high levels of cleanliness and sterility are required. Common applications are medical devices, pharmaceutical and semiconductor manufacturing. The FDA mandates the use of cleanrooms to create GMP manufacturing factories.
A: Cleanrooms are used for manufacturing where high levels of cleanliness and sterility are required. Common applications are medical devices, pharmaceutical and semiconductor manufacturing. Cleanrooms use HEPA filters to remove particles from the air.
A: Very clean. A class 100 cleanroom has 100 particles per cubic foot. 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.
A: Medical device and pharmaceutical manufacturing requires sterile environments to produce their products. Cleanrooms provide this sterile super clean manufacturing space which reduces the chance of contamination getting in your medicine. Semiconductor manufacturers produce devices with ultra small super dense features. Examples are computer chips for your cell phone or PC. If contamination were to get on the chip during manufacturing, they would not work.
ISO 5 is a super clean cleanroom classification. A cleanroom must have less than 3,520 particles >0.5 micron per cubic meter and 250-300 HEPA filtered air changes per hour. The equivalent FED standard is class 100 or 100 particles per cubic foot. Common applications are semiconductor manufacturing and pharmaceutical filling rooms.
ISO 6 is a very clean cleanroom classification. A cleanroom must have less than 35,200 particles >0.5 micron per cubic meter and 180 HEPA filtered air changes per hour. The equivalent FED standard is class 1000 or 1000 particles per cubic foot.
ISO 7 is a common clean cleanroom classification. A cleanroom must have less than 352,000 particles >0.5 micron per cubic meter and 60HEPA filtered air changes per hour. The equivalent FED standard is class 10.000 or 10,000 particles per cubic foot. Common applications are pharmacy USP800 compounding rooms, electronics manufacturing and medical device manufacturing.
ISO 8 is the least clean cleanroom classification. A cleanroom must have less than 35, 200,000 particles >0.5 micron per cubic meter and 20 HEPA filtered air changes per hour. By comparison a typical office space would be 5-10 times more dirty. The equivalent FED standard is class 100,000 or 100,000 particles per cubic foot. Common applications include plastic extrusion for medical devices, e-liquid manufacturing, and nutraceutical packaging.
