Detailed Profiles of Key Purification Equipment
1. Air Shower / Cargo Shower
- Function: An essential buffer zone between clean and non-clean areas. Uses high-velocity filtered air to remove dust from personnel or goods.
- Key Feature: Electronic Interlocking Doors act as an airlock to prevent unpurified air from entering the clean zone.
- Customization (Cargo Shower): Typically non-standard (customized) based on the logistics passage size. Options include infrared voice prompts and automatic sliding doors.
2. Pass Box
- Purpose: Transfers small items between rooms to minimize door openings.
- Construction: SUS304 stainless steel interior for easy cleaning; Mechanical or Electronic interlock to prevent cross-contamination.
3. HEPA Supply Air Outlet
- Application: Terminal air supply device for Class 1,000 to 100,000 cleanrooms.
- Components: Static pressure box, HEPA filter, diffuser plate. Available in bottom-loading designs for easy filter replacement from within the cleanroom.
4. Clean Bench
- Local Purification: Provides an ISO Class 5 (Class 100) sterile and dust-free micro-environment.
- Technical Specs: Vibration-damping motor mounts, SUS304 work surfaces, and dual-ring sealing systems between the filter and frame to ensure zero leakage.
5. Fan Filter Unit
- The "Cleanroom Lung": A self-contained air purification unit. Can be ceiling-mounted or bracket-supported.
- Performance: Uniform air velocity of 0.45m/s ± 20%. Ideal for upgrading existing facilities or constructing new large-scale cleanrooms with low noise and vibration.
