class 5 Electronic clean room-Non ESD, Acrylic, Aluminum Profile, AC Blower
The cleanliness of a cleanroom is usually measured in Particles per Cubic Meter (PCM) or Particles per Cubic Foot (PCF). Cleanliness standards can vary depending on the industry and application, but here are some general cleanliness standards:
ISO 14644: This is an international standard that defines cleanliness levels for cleanrooms.The ISO 14644-1 standard specifies particle count limits for various cleanliness levels. For example, an ISO 14644-1 Class 1 cleanroom requires a particle count of no more than 10,000 PCM per cubic meter.
US Federal Standard 209E: This is a US federal standard that has been superseded by ISO 14644. However, it is still used by some industries to measure the cleanliness of cleanrooms.
GMP Standards: Good Manufacturing Practice (GMP) standards are commonly used in pharmaceutical manufacturing to specify cleanliness requirements. These standards will vary depending on the type of product and application.
Food Industry Standards: The food processing sector may use its own standards to ensure product hygiene and safety, which includes controlling levels of microorganisms and other contaminants. The choice of cleanliness standards depends on the specific application and is usually based on product sensitivities and industry regulations. Clean sheds require regular maintenance and monitoring to ensure that they meet or maintain the required cleanliness standards.
FFU with fan inhalation of external air, after the filter, high efficiency filter air will finally be sent out of the channel mouth with uniform wind speed, due to the non-stop provision of clean air clean shed will produce air flow layer, air flow upward, the most red will form a cycle, thus ensuring the cleanliness of the clean shed.
Ventilation: Clean rooms are usually equipped with efficient ventilation systems to maintain air flow and reduce airborne particles and other contaminants. The ventilation system also removes unclean air and brings in filtered fresh air.
Filters: Ventilation systems in clean rooms include high-efficiency air filters, usually such as HEPA (High Efficiency Particulate Air) or ULPA (Ultra High Efficiency Particulate Air) filters. These filters capture and remove tiny particles, ensuring that airborne particulate matter is kept at acceptable levels.
Air Quality Control: Cleanrooms usually utilize negative or positive pressure systems to prevent outside air from entering or inside air from escaping. This helps maintain a clean environment.
