ZJNF Cleanroom Laminar Flow Modular Clean Booth For Semiconductors Cosmetics Biomedicine Factory

Here is the English translation of the cleanroom booth introduction, incorporating the context from our previous discussion:

‌Cleanroom Booth Introduction‌

A cleanroom booth is a localized high-cleanliness environment device widely used in industries and scientific research that require strict control of dust, microorganisms, or chemical contamination. Below is a detailed explanation of its core applications, typical use cases, and safety requirements.

‌1. Primary Functions‌

Clean booths achieve air purification through high-efficiency filtration systems (e.g., FFU fan filter units), with key capabilities including:

• ‌Particle Control‌: Reducing airborne dust particles to ensure quality in precision manufacturing.
• ‌Microbial Isolation‌: Preventing bacterial contamination in pharmaceuticals, food, and other industries.
• ‌Environmental Stability‌: Maintaining constant temperature and humidity to avoid fluctuations affecting production.

‌2. Typical Applications‌

1. ‌Electronics & Semiconductor Industry‌

   • Used in chip and LCD panel production, requiring ISO Class 1-3 cleanliness (e.g., ≤1,000 particles ≥0.1μm per cubic meter).
   • Example: TSMC’s 5nm fabs use vertical laminar flow designs, achieving ISO Class 2 in critical zones.

2. ‌Pharmaceuticals & Biotechnology‌

   • Sterile drug production and cell culture must comply with GMP standards, with biosafety cleanrooms requiring positive pressure control.
   • Example: A pharmaceutical company reduced contamination risk to <0.01% with an ISO Class A aseptic filling line.

3. ‌Food & Precision Instruments‌

   • Prevents microbial contamination in food processing and avoids dust interference in precision instrument assembly.

‌3. Safety & Compliance Requirements‌

1. ‌Design & Construction Standards‌

   • Must comply with GB50073 Cleanroom Design Code, with contractors requiring relevant qualifications.
   • Hidden works require client approval, and system commissioning must involve certified technicians.

2. ‌Environmental Control‌

   • ‌Airflow‌: Vertical laminar flow design with ≥500 air changes/hour.
   • ‌Filtration‌: HEPA/ULPA filters with ≥99.9995% efficiency.
   • ‌Pressure Gradient‌: 10–15 Pa between clean and non-clean zones.

3. ‌Materials & Equipment‌

   • Frame: Aluminum alloy or stainless steel; walls: anti-static coated steel panels (surface roughness Ra <0.13μm).
   • FFUs: Variable frequency control, noise ≤42 dB.

4. ‌Safety Measures‌

   • Equipped with VESDA smoke detection and gas suppression systems.
   • Biosafety booths require negative pressure to prevent contamination leakage
