• Reliable liquid sealing

The liquid sealing structure forms a continuous sealing interface between the filter frame and housing, helping minimize air bypass around the filter and supporting the overall integrity of the filtration system.

• High-efficiency particle control

The filter is designed to provide effective removal of airborne particulate contaminants, making it suitable for environments where controlled air cleanliness is essential.

• Designed for terminal filtration

As a Terminal HEPA Filter, it is suitable for systems where filtered air is supplied directly into cleanroom or other controlled areas.

• Suitable for ceiling installation

The filter can be integrated into appropriate ceiling-mounted air supply configurations as a Cleanroom Ceiling HEPA Filter, providing a practical solution for terminal clean air delivery.

• Stable performance in critical environments

The combination of high-efficiency filtration and perimeter sealing helps support consistent operation in applications where air cleanliness and filtration reliability are important.

• Adaptable to different filtration systems

Depending on the system configuration, the filter can be incorporated into terminal filtration units, FFU systems, cleanroom ceilings, and other air-handling equipment.

The sealing structure is an important part of terminal HEPA filtration because air bypass around the filter can reduce the effectiveness of the overall filtration system. The filter uses a liquid seal configuration in which the sealing groove or tank contains a suitable gel sealant. During installation, the corresponding housing knife edge engages with the sealing medium to create a continuous sealing interface.

This design provides several functional benefits:

• Continuous perimeter sealing helps reduce uncontrolled air leakage around the filter frame.
• Gel-based sealing provides a flexible sealing interface between the filter and housing.
• Knife-edge engagement helps establish a defined sealing path during filter installation.
• Reduced air bypass helps maintain the intended performance of the terminal filtration system.
• Reliable housing integration makes the configuration suitable for cleanroom terminal air supply applications.

This combination of liquid sealing and high-efficiency filtration makes the Terminal Liquid Seal HEPA Filter for Cleanroom suitable for applications where both filtration performance and housing integrity need to be considered.

• Pharmaceutical cleanrooms

Suitable for pharmaceutical production areas, sterile processing spaces, preparation rooms, and other controlled environments where particulate contamination needs to be carefully controlled. The filter can serve as a Pharmaceutical Cleanroom HEPA Filter in suitable terminal air supply systems.

• Hospitals and healthcare facilities

Applicable to operating rooms, isolation areas, treatment spaces, and other healthcare environments requiring controlled air filtration.

• Laboratories and research facilities

Suitable for laboratories and research areas where maintaining controlled air cleanliness is important for testing, research, and sensitive processes.

• FFU and cleanroom systems

The filter can be incorporated into suitable FFU configurations as a HEPA Filter for FFU, depending on the equipment design, installation method, and required filter dimensions.

• Electronics and precision manufacturing

Suitable for controlled production environments where airborne particles may affect sensitive components, products, or manufacturing processes.

Terminal filtration systems can vary according to the cleanroom design, air-handling equipment, installation configuration, and available housing space. Filter selection should therefore be matched to the specific requirements of the application.

Depending on the product configuration, available options may include:

• Different filter dimensions and depths
• Suitable frame and housing configurations
• Different filtration efficiency grades
• Liquid or gel sealing configurations
• Terminal ceiling and equipment installation requirements
• Customized solutions for specific cleanroom filtration systems

For new cleanroom projects or replacement applications, the required dimensions, filtration grade, installation configuration, and sealing requirements should be confirmed before ordering. This helps ensure that the filter is properly matched to the terminal air supply system and its operating conditions.
