The high efficiency exhaust outlet is applied to the high efficiency filtersystem of high-grade biosafety laboratory,which meets the require-ments of GB19489-2008“sterilizing and sterilizing the exhaust airlter in situ”in “General Requirements for Laboratory Biosafety”.
The efficient exhaust outlet is an exhaust flter device installed in theclean room,which is used for the exhaust flter of the negative pres-sure workshop system to isolate toxic,carcinogenic,radioactive andbiological dangerous dust and gas,and prevent the indoor harmfulsubstances from being discharged into the exhaust system.The deviceuses the automatic scanning and pick-up technology.The high eff-ciency air flter and the equipment frame are scanned in situ,and theflter is disinfected and sterilized through the HEPA flter by using gasdisinfectant,which can display the resistance of the high efficiency airoverizer in real tme.

What is a HEPA Filter Box and Why It Matters?

HEPA Filter Box (High-Efficiency Air Supply Box) serves as the terminal air filtration device in cleanroom systems, filtering air supplied into clean zones to remove particles ≥0.3μm and microbial contaminants.

Its core structure includes:

  • Enclosure (Carbon Steel / Stainless Steel / Aluminum)
  • High-Efficiency Filter (HEPA or ULPA)
  • Diffuser Plate
  • Sealing gasket / Gel seal
  • Adjustable damper and inspection port

HEPA filter boxes are typically installed at the end of cleanroom ceilings or supply ducts to achieve secondary air filtration and uniform diffusion. This ensures stable compliance with ISO standards for air velocity, direction, and cleanliness within the clean zone.

In GMP pharmaceutical and electronics manufacturing environments,
it serves as critical equipment for achieving terminal cleanliness control and preventing cross-contamination.

Key Advantages of Our HEPA Filter Box

  • High-Efficiency Filtration Performance (Efficiency Up to 99.9995%@0.3μm): Utilizes internationally certified HEPA/ULPA filter cartridges, validated through EN1822 or ISO 29463 testing.
  • Leak-Free Design: Utilizes gel seal or knife edge sealing methods to eliminate bypass leakage risks.
  • Uniform Air Distribution: Incorporates an internal diffuser plate design to ensure consistent air velocity across the discharge surface, meeting laminar flow requirements.
  • Flexible Installation: Supports ceiling-recessed, flange-mounted, side-mounted, and other configurations to adapt to diverse cleanroom layouts.
  • Easy Maintenance & Validation: Equipped with PAO (DOP) test ports and differential pressure monitoring ports for rapid on-site validation.
  • Customizable & Documented: Provides complete IQ/OQ/PQ validation documentation, material certificates, and test reports to meet GMP/FDA audit requirements.

Frequently Asked Questions about HEPA Filter Box Manufacturer

What is the difference between a HEPA Filter Box and a HEPA Filter?

Answer:
A HEPA Filter is a standalone filtration element, while a HEPA Filter Box is a complete terminal filtration system, typically comprising a filter, housing, airflow distribution plate, sealing gasket, inspection port, and damper.

The filter box provides an installation sealing structure and uniform airflow distribution, ensuring more stable and reliable air cleanliness.

Answer:
Our HEPA Filter Box utilizes H13–U15 grade filter cartridges (EN1822 / ISO 29463 standard), achieving filtration efficiency of 99.995%–99.999% (99.99995%@0.3μm). It is suitable for various high-grade cleanrooms, operating rooms, biological laboratories, and microelectronics manufacturing environments.

Answer:
Yes. We provide comprehensive OEM/ODM customization services, including personalized designs for enclosure materials (galvanized steel/stainless steel/aluminum alloy), sealing methods (gel seal/gasket/knife edge), airflow volume, structural dimensions, and interface orientation.
