Main Specification for HEPA Box

Engineering Application Scenarios

1. Pharmaceutical & Biotechnology

• • Grade A Point Protection for Aseptic Filling Lines: Covers critical points like filling needles, stopper bowls.

  • Cell Therapy Processing Areas: Provides a local ultra-clean environment for cell manipulation.

  • QC Laboratories: Protection for microbiology testing, sterility testing benches.

  • Isolator/GLP Supply Air: Provides clean background air for isolator interiors.

2. Medical Devices & Electronics

• • Precision Assembly Stations: Chip mounting, lens assembly, sensor production.

  • Optical Component Cleaning Areas: Prevents dust settlement on product surfaces.

  • Packaging Zones: Final protection before packaging of sterile devices.

3. Hospitals & Laboratories

• • Pharmacy Intravenous Admixture Service (PIVAS): Compounding of IV drugs.

  • Surgical Laminar Flow Assist: Provides supplemental clean air over surgical sites.

  • PCR Laboratories: Contamination prevention in sample prep areas.

4. Food & Cosmetics

• • High-Cleanliness Filling Zones: Protection for filling high-end skincare or functional foods.

  • Microbiology Testing Labs: Sample handling workstations.

6. Project Design & Installation Key Points

Design Considerations

1. 1. Airflow Integration:

      • HEPA Box airflow direction must align with the room's overall airflow pattern.

      • Avoid conflict with room return air locations.

      • Consider effects of heat generated by processes.

   2. Layout Planning:

      • Cover critical process points (Point-of-Use).

      • Maintain adequate spacing between multiple HEPA Boxes to prevent airflow interference.

      • Reserve space for maintenance and filter changes.

   3. System Integration:

      • Air volume balancing calculations with HVAC system.

      • Electrical integration with room control systems.

      • Placement of pressure monitoring points.

Products Description

• Housing/Casing: Constructed from stainless steel, aluminum, or coated galvanized steel for durability, cleanability, and corrosion resistance.HEPA/ULPA Filter: The core filtration element, mounted on the discharge side, providing final air cleaning.

• Centrifugal Blower Fan: Typically a backward-curved impeller design, providing stable airflow with good energy efficiency and low noise. Units may feature single or multiple fans (for redundancy).

• Pre-filter: Usually a primary (G4) or medium-efficiency (F8) filter located at the fan inlet. It protects the main HEPA filter and extends its service life by capturing larger particles.

• Control System:

  • Speed Control: Modern FFUs predominantly use Electronically Commutated (EC) motors, allowing infinite variable speed control via 0-10V DC, PWM signals, or network commands. This enables precise airflow adjustment and significant energy savings compared to older AC motor designs.

  • Monitoring: May include integrated differential pressure sensors (to monitor filter loading), status indicator lights, alarm functions, and communication interfaces for connection to Building Management Systems (BMS).

• Airflow Diffuser/Perforated Plate: Mounted below the filter, it helps to equalize and stabilize the discharged airflow, promoting uniform laminar flow.
