Gel Seal HEPA Filter

Gel Seal HEPA Filter (Gel HEPA Filter) is the top-grade leak-proof high-efficiency terminal filter designed for ultra-strict ISO5 (Class 100) cleanroom environments, widely adopted in pharmaceutical GMP Grade A/B workshops and hospital high-risk operating rooms.

This lightweight flat plate structure perfectly fits FFUs, HEPA terminal filter boxes, laminar flow ceilings, air showers, dynamic pass boxes and hard/soft wall clean booths. It eliminates micro-particles, bacteria and viral aerosols to maintain ISO5–ISO8 ultra-clean environments, mandatory final filtration component for pharmaceutical, hospital, semiconductor and food aseptic production projects.

Main Structure & Material Breakdown

1. Outer Frame

3 customizable frame materials for different working environments:

• Extruded aluminum alloy frame (Standard Cleanroom Grade)

  Lightweight, high rigidity, anti-rust, easy disassembly, universal matching all FFU and ceiling filter racks, most widely used for medical & pharma clean zones.

• Galvanized steel frame (Economical Industrial Type)

  High structural strength, cost-effective for electronics factory medium-grade cleanrooms.

• SUS304 stainless steel frame (Premium Corrosion-Resistant Grade)

  Resistant to repeated alcohol, hydrogen peroxide and chlorine disinfection, dedicated to hospital operating rooms and high-humidity sterile filling workshops.

  Standard filter depth: 50mm / 70mm / 90mm / 110mm thin plate sizes for compact installation space.

2. Filtration Media & Separator (Core Mini-Pleat Design)

• Filter Media: Ultra-fine borosilicate micro glass fiber (PTFE anti-corrosion media optional for chemical labs)

  • H13: ≥99.99% efficiency for 0.3μm particles (MPPS)

  • H14: ≥99.995% efficiency for 0.3μm particles (GMP/FDA mandatory grade)

  • ULPA U15–U19: ≥99.9995% efficiency for 0.12μm submicron particles for semiconductor ultra-clean zones

• Separator: Hot-melt polypropylene bead strip (no metal aluminum partition)

  Uniform narrow pleat spacing stabilizes airflow, avoids metal rusting and fiber shedding, reduces overall filter weight and initial pressure drop.

• Sealing Craft: Two-component PU glue fully pours and seals media pack to frame, zero bypass air leakage inside the filter core.

Compliance Standards

• Filtration test standard: EN1822:2019 (H13/H14/ULPA U15–U19)

• Cleanroom classification: ISO 14644-1 (ISO5 ~ ISO8 / Class100 ~ Class100,000)

• Medical & pharmaceutical norms: GMP, FDA cGMP, IEST RP-CC001 aerosol scan test specification

• Material certification: CE, ISO9001, RoHS, SGS environmental test
