Mini-pleat HEPA filters with gel seals are specialized high-efficiency filters designed for
critical environments where a 100% leak-proof connection is mandatory. Unlike mechanical gasket
compression, these filters feature a perimeter channel filled with a non-hardening,
"self-healing" silicone or polyurethane gel. This gel creates an airtight seal by receiving a
"knife-edge" from the mounting housing, making them the preferred choice for pharmaceutical and
semiconductor facilities.
Key
Benefits
- 🛡️ Zero Leakage: The
knife-edge-to-gel interface provides a superior airtight seal compared to
traditional gaskets.
- 🔧 Ease of Maintenance: "Top gel" or
"side gel" designs allow for quick, tool-free installation and removal.
- 🏗️ Durability: Expanded metal face
guards protect the delicate pleat packs during handling and installation.
- 📳 Vibration Resistance: The gel acts as a cushion, maintaining the
seal even with minor system vibrations.
Technical Specifications
- 📊 Efficiency: Typically rated for
99.97% to 99.999% @ 0.3 µm (Grades H13 to U15 per EN 1822).
- 🧪 Filter Media: High-density
micro-glass fibre paper in a mini-pleat configuration.
- 💧 Sealant Technology: Viscous,
bacteriostatic gel that remains flexible and does not harden.
- 🏗️ Frame Materials: Anodized extruded aluminium, stainless steel,
or galvanized steel.
