Clean Booth: Compact Solution for Controlled Cleanliness
2025-11-21
Key Technical Specifics
- Modular Structure:
- Frame: Aluminum alloy (lightweight, corrosion-resistant) or stainless steel (for high-humidity/cleanliness demands);
- Enclosure: PVC curtain (easy access) or acrylic/PC panels (dustproof, transparent);
- Customizable size: Common single-person models (1.2m×1.0m×2.1m) to multi-station setups (3m×2m×2.2m).
- Filtration & Airflow:
- HEPA H13/H14 filters (≥99.995% efficiency for 0.3μm particles) or ULPA U15 (≥99.9995% for 0.12μm particles);
- Air change rate: 60-120 times/hour (adjustable via frequency converter);
- Vertical laminar airflow (0.3-0.5m/s wind speed) to avoid cross-contamination.
- Pressure Control:
- Positive pressure: 10-30Pa (monitored by differential pressure gauge), with airtight seals to block external particles.
Typical Applications (with Specific Scenarios)
- Electronics: Semiconductor chip bonding, circuit board soldering (anti-static models available);
- Pharmaceuticals: Small-batch API packaging, medical dressing assembly (microbe-controlled versions);
- Precision Manufacturing: Lens polishing, miniature component assembly;
- Laboratories: Sample preparation for HPLC/ICP testing, cell culture (bio-safe variants).
Selection & Usage Details
- Selection Tips:
- Match cleanliness class to needs (e.g., Class 100 for chip production, Class 10,000 for pharmaceutical packaging);
- Choose anti-static design for electronics, corrosion-resistant materials for chemical environments.
- Maintenance Essentials:
- Filter replacement: HEPA (6-12 months), pre-filter (1-3 months, washable);
- Daily checks: Differential pressure (should not deviate ±30% from baseline), fan noise (≤65dB standard);
- Operator requirements: Wear cleanroom suits, shoe covers, and hairnets; avoid bringing lint-prone items.
