A clean room class 1000 is a controlled environment designed to maintain low levels of particulates, such as dust, airborne microbes, and chemical vapors, to ensure a contamination-free workspace for sensitive processes. Clean rooms are classified based on the level of cleanliness they provide, and “Clean Room 1000” refers to a specific level of cleanliness defined by the number of particles allowed in the air.

Clean Room 1000 Classification

The classification “Clean Room 1000” is based on the ISO 14644-1 or Federal Standard 209E standards:

1. ISO 14644-1 (Modern Standard):
   • Equivalent classification: ISO 6
   • Maximum allowable particles (per cubic meter of air):
     • ≥0.1 μm: 1,000,000 particles
     • ≥0.2 μm: 237,000 particles
     • ≥0.3 μm: 102,000 particles
     • ≥0.5 μm: 35,200 particles
     • ≥1.0 μm: 8,320 particles
     • ≥5.0 μm: 293 particles
2. Federal Standard 209E (Obsolete Standard):
   • Class 1000: The clean room permits no more than 1,000 particles (≥0.5 microns) per cubic foot of air.

Applications of Clean Room 1000

Clean Room 1000 environments are used in industries where moderate levels of cleanliness are required for processes or products to function correctly, such as:

1. Electronics Manufacturing:
   • Assembly of circuit boards or electronic components.
   • Testing and handling of sensitive electronic devices.
2. Pharmaceuticals:
   • Manufacturing non-sterile medical products.
   • Packaging of sensitive drugs and devices.
3. Medical Devices:
   • Fabrication of non-critical devices like prosthetics or diagnostic tools.
4. Semiconductors:
   • Production and inspection of less complex microchips.
5. Optics:
   • Assembly of lenses and optical instruments.

Key Features of a Clean Room 1000

1. Air Filtration:
   • High-Efficiency Particulate Air (HEPA) filters or Ultra Low Penetration Air (ULPA) filters are used to remove contaminants.
   • Laminar airflow ensures uniform air movement to prevent particle accumulation.
2. Environmental Controls:
   • Temperature, humidity, and pressure are controlled to meet process requirements.
   • Positive pressure prevents external contaminants from entering.
3. Clean Room Attire:
   • Personnel wear gloves, masks, gowns, and sometimes full-body suits to minimize contamination.
4. Cleaning Protocols:
   • Regular cleaning schedules and strict procedures for equipment, surfaces, and tools are followed.
5. Monitoring:
   • Particle counters and sensors are used to continuously monitor air quality.
