Gel Seal HEPA Filter – Terminal Filtration for Cleanroom HVAC Systems
Designed for pharmaceutical cleanrooms, biotech laboratories, and hospital operating rooms.
Overview
This gel-seal high-efficiency filter serves as the final stage of filtration in cleanroom air handling systems. It captures sub-micron particles down to 0.12–0.3 µm, ensuring ISO Class 5 (Class 100) or better air quality in critical environments.
Key Specifications
Parameter Detail Filter Grade U15 (≥99.9995%) / H14 (≥99.995%) per EN 1822 Media Microfine glass fiber paper Frame Aluminum alloy Gel Seal Blue gel sealant (PU gel) – side liquid-seal channel design Adhesive Eco-friendly polyurethane AB adhesive Protection Double-sided baked enamel-coated wire mesh Service Life 12–18 months (depending on pre-filtration and environment)
Why Gel Seal?
The side-channel liquid gel seal provides superior airtightness compared to conventional gaskets. It allows for leak-free installation and easy filter replacement without damaging the housing frame – critical for maintaining containment integrity in sterile manufacturing.
Applications
- Pharmaceutical manufacturing cleanrooms (Grade A/B/C/D)
- Biotech R&D laboratories
- Hospital operating rooms & isolation wards
- Electronics assembly clean zones
- Food & beverage sterile processing
Installation Note
Designed for side-gel-seal housings. The filter slides into the frame, where the gel forms a continuous leak-tight seal against the channel walls. No additional gasket or clamping required.
Custom Options
- Alternative sizes and thicknesses
- Frame color and finish
- Private labeling available

Ultra-Thin EFU (Equipment Fan Filter Unit) – Low-Profile Clean Air Solution for Space-Constrained Production Equipment & Low-Ceiling Cleanrooms
Product Overview
The EFU (Equipment Fan Filter Unit) is an ultra-thin fan filter unit specifically engineered for clean air applications where installation space is severely restricted. With a compact profile ranging from 70mm to 190mm in height, it is designed to be embedded directly into production equipment tops or low-ceiling plenum spaces, delivering localized Class 100 (ISO 5) clean air precisely where it is needed most.
Key Applications
- Space-limited equipment: SMT mounters, lithography machines, wafer inspection tools, and other precision manufacturing equipment with extremely tight overhead clearance
- Low-ceiling retrofits: Aging factory buildings or cleanrooms with insufficient plenum height where standard FFU (280–320mm) cannot be installed
Core Advantages
- Ultra-slim footprint (70–190mm height) – enables installation in the most confined overhead spaces
- Targeted microenvironment control – creates a positive-pressure clean zone directly over the critical work area, isolating contamination at the source
- Low vibration design – minimizes interference with precision alignment processes (e.g., SMT placement, lithography)
- Flexible maintenance – supports top-access or bottom-access filter replacement to accommodate tight installation constraints
- Customizable sizes – dimensions tailored to match specific equipment footprints

General-Purpose FFU (Fan Filter Unit) – Class 100 Local Cleanroom Air Purification for Semiconductor, Biotech & Optoelectronics
FFU Application Scenarios & Core Advantages
The core value of FFU (Fan Filter Unit) lies in providing stable, reliable local or overall clean air environments for spaces with stringent cleanliness requirements. Its primary applications include:
Large-Scale Industrial Cleanrooms: Widely used in electronics, semiconductors, flat-panel displays, optoelectronics, and new energy battery manufacturing, meeting cleanliness requirements of ISO Class 6 (FS209E Class 1000) and above.
Production Lines & Localized Purification: Can be used individually or in series to form continuous Class 100 (ISO Class 5) clean assembly lines, providing localized purification for critical processes such as precision component assembly and inspection.
Modular Clean Equipment: Serves as the core purification unit in constructing small-scale clean devices, including clean benches, clean booths, and clean transfer cabinets.
Key Advantages:
High flexibility and reusability, enabling zoned control and adaptable layout
Negative pressure design in the plenum relative to the cleanroom prevents unfiltered air leakage, enhancing safety
Shortens construction timelines, saves space, and reduces long-term operating costs.
Custom dimensions are available upon request. Standard cabinet sizes include 575×575×280 mm, 1175×575×320 mm, and 1175×1175×320 mm.
