Detailed Product Description for "Medical Aluminium H13 H14 Gel Seal Fiberglass HEPA Filter for HEPA Box"
This description covers technical parameters, application scenarios, and selection recommendations, suitable for medical clean environments.
Medical-Grade Aluminium-Frame H13/H14 Gel-Sealed Fiberglass HEPA Filter (for HEPA Boxes)
Product Overview
Designed specifically for high-cleanliness environments such as medical cleanrooms, operating rooms, and biosafety laboratories, this filter features an aluminium frame and gel-sealing technology to ensure a leak-free performance. The filter media, made of ultrafine glass fibers (diameter ≤1μm), meets the H13 (≥99.95%) or H14 (≥99.995%) filtration efficiency standards (EN1822). It effectively intercepts bacteria, viruses, and particulate contaminants, satisfying cleanliness requirements from ISO Class 5 (Class 100) to ISO Class 8 (Class 100,000).
Core Features
Efficient Filtration and Low-Leakage Design
H13/H14 Filter Media: Achieves filtration efficiencies of 99.95% and 99.995% for 0.3μm particles, respectively, meeting stringent medical industry standards.
Gel-Sealing Technology: Utilizes polyurethane or silicone gel to fill gaps between the filter element and frame, eliminating leakage risks associated with traditional mechanical seals and ensuring 100% bypass sealing.
Aluminium Frame: Corrosion-resistant and free from particle shedding, suitable for medical environments requiring biocompatible materials.
Structural Optimization and Durability
Hot-Melt Adhesive Separators: Replace traditional aluminum foil separators, reducing the risk of metal ion release while lowering pressure drop (initial pressure drop ≤220Pa @H14 grade).
Protective Screen Design: Double-sided galvanized iron mesh or stainless steel mesh prevents filter media damage during transportation/installation, extending service life.
Fire Resistance: The filter media complies with the UL900 Class 1 fire safety standard, and the aluminum frame withstands high temperatures (≤250°C).
Compatibility and Ease of Maintenance
Standard Size Compatibility: Common specifications include 610×610×292mm and 592×592×150mm, compatible with mainstream HEPA boxes (e.g., Dynamic, Camfil).
Quick-Replacement Design: The gel-sealed layer supports integral filter element insertion/removal, reducing maintenance time by over 50%.
Lightweight Structure: The aluminum frame is 40% lighter than stainless steel, facilitating high-altitude installation.

Application Scenarios
Medical Cleanrooms
Terminal filtration in operating rooms, ICUs, and negative-pressure wards to prevent cross-infection.
Sterile formulation workshops in pharmaceutical plants (e.g., injection filling lines, freeze-dried powder production areas).
Air purification in medical device cleaning/sterilization areas.
Biosafety Protection
Exhaust HEPA filtration in BSL-3/BSL-4 laboratories to intercept highly pathogenic pathogens.
Ventilation systems in animal experiment centers to control allergen dispersion.
Specialized Medical Equipment
Air circulation filtration modules for laminar flow hoods, isolators, and biosafety cabinets.
Radioactive particulate filtration in nuclear medicine wards (requires activated carbon filter layer).
Selection Recommendations
Filtration Efficiency Matching
For general medical environments (e.g., outpatient clinics, general wards): H13 grade is sufficient.
For high-risk scenarios (e.g., operating rooms, biosafety laboratories): Prioritize H14 grade and add pre-filtration (G4+F8) to extend HEPA lifespan.
Sealing and Temperature Resistance Requirements
High-humidity environments (e.g., disinfection rooms): Choose silicone gel seals (mold-resistant).
High-temperature sterilization scenarios (e.g., steam sterilizer exhaust): Select silicone seals resistant to 150°C and PTFE-coated filter media.
Structural and Installation Optimization
Compact spaces: Opt for thin designs (thickness ≤150mm) or side-mounted frames.
Corrosion resistance needs: 316L stainless steel frame with epoxy resin coating for chemical disinfectant environments.
Anti-static requirements: Conductive treatment on filter media surface (resistance ≤10⁶Ω) to prevent dust adhesion.
