HEPA/ULPA Filtration Systems ISO Class 5 (Class 100) Workbench

Cleanroom laminar flow workstation's functions:

‌1. Core Functions‌

A clean bench (Laminar Flow Workstation) is a critical localized purification device in cleanrooms, providing ISO Class 5 (Class 100) clean and sterile environments through ‌HEPA/ULPA filtration systems‌. Its primary functions include:

• ‌Contamination Isolation‌: Creates a unidirectional airflow barrier (vertical/horizontal) to block external dust and microorganisms from entering the work area.
• ‌Product Protection‌: Ensures precision electronic components, biological samples, and pharmaceuticals remain contamination-free, significantly improving product yield (e.g., semiconductor chip pass rates can increase from 10% to over 90%).
• ‌Operator Safety‌: In biomedical applications, prevents exposure to hazardous pathogens or chemicals.

‌2. Technical Principles‌

• ‌Air Filtration‌:
  Fan draws in air → Pre-filter (primary) → HEPA/ULPA filter (≥99.97% efficiency @0.3μm) → Clean air discharged vertically/horizontally.
• ‌Airflow Control‌:
  • ‌Vertical Flow‌: Top-down airflow, bottom return (ideal for sterile pharmaceutical operations, higher noise).
  • ‌Horizontal Flow‌: Front-to-back airflow (quieter but more susceptible to operator interference).

‌3. Key Applications‌

‌4. Additional Features & Maintenance‌

• ‌Smart Controls‌: Some models include UV sterilization, pressure gauges, and touch panels for real-time filter monitoring.
• ‌Maintenance Requirements‌:
  • Regular filter replacement (pre-filters every 3-6 months, HEPA/ULPA every 1-2 years).
  • Wipe surfaces with 70% ethanol to prevent chemical corrosion.
