595mm × 595mm × 380mm Stainless Steel HEPA Box For Pharmaceutical Manufacturing

Certainly, let me provide you with details about HEPA Boxes:

1. Definition and Purpose:

   • HEPA (High-Efficiency Particulate Air) Boxes are specialized enclosures designed to provide a controlled and ultra-clean work environment.
   • They are used to create a localized area of high air purity, often within a larger cleanroom or laboratory setting.

2. HEPA Filtration:

   • The key component of a HEPA Box is the HEPA filter, which is capable of removing at least 99.97% of airborne particles 0.3 microns or larger in size.
   • This high-efficiency filtration ensures that the air inside the HEPA Box is free from contamination, providing a safe and clean workspace.

3. Design and Construction:

   • HEPA Boxes are typically made of durable, non-shedding materials such as stainless steel, tempered glass, or clear acrylic.
   • They feature a transparent enclosure that allows for easy visibility and accessibility while maintaining the clean air environment.
   • The boxes often have built-in HEPA filters, either at the rear or top of the enclosure, which draw in ambient air and force it through the filter before circulating it into the work area.

4. Airflow and Pressure:

   • HEPA Boxes utilize a unidirectional, laminar airflow pattern to create a clean work zone.
   • This controlled airflow helps to sweep away any airborne particles and prevent their entry into the workspace.
   • The boxes may also be equipped with positive pressure systems to maintain a higher pressure inside the enclosure compared to the surrounding environment, further enhancing the cleanliness.

5. Applications and Usage:

   • HEPA Boxes are commonly used in industries and laboratories that require an ultra-clean work environment, such as:
     • Pharmaceutical manufacturing
     • Biotechnology research
     • Microelectronics assembly
     • Nanotechnology
     • Medical device production

6. Operational Procedures and Maintenance:

   • Users of HEPA Boxes must follow strict protocols to maintain the integrity of the clean environment, including proper gowning, minimizing disruptions to the airflow, and performing regular cleaning and filter maintenance.
   • Periodic certification and validation processes are necessary to ensure the HEPA Box continues to meet the required cleanliness standards and regulatory requirements.

Definition: HEPA box is the terminal device in purified air supply system.

Operation Principle: The HEPA box requiring filed leak detection is provided with PAO dusty entry and upstream concentration detection mouth, and differential pressure detection mouth and lower damper based on customers’ requirements.

Advantages of ABS HEPA Box

• One time injection, no leakage risk, smooth inner surface, dust-free and easy to clean.

• Acid, alkali and salt-resistant, formaldehyde-resistant, VHP and O 3 Sterilize.

Advantages of Plastic-spray Steel Plate

• Full welding with mechanical welding machine, high efficiency.

• No leakage risk.

• The box is not easy to deform.

Standard size and Parameter

Note: For ABS box,the hole size should be 5mm larger than that in the list,for plastic-spray box with DOP outside,the hole size should be 5mm smaller than that in the list .We can also produce other sizes according to customer’s requirements.
