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

‌Industry‌	‌Applications‌	‌Airflow Type‌
‌Electronics‌	Chip packaging, precision instrument assembly (prevents micro-dust-induced short circuits)	Horizontal
‌Biopharma‌	Cell culture, vaccine filling (sterile environment required)	Vertical
‌Food Testing‌	Microbial testing, aseptic packaging (HACCP compliant)	Vertical
‌R&D Labs‌	Gene sequencing, optical experiments (prevents sample contamination)	Horizontal

‌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.
