Mini-pleat HEPA filters with gasket seals are compact, high-efficiency air filters designed for
final-stage filtration in space-constrained HVAC systems. Unlike deep-pleat models that use
aluminium separators, these utilize hot-melt adhesive beads to maintain precise pleat spacing,
maximizing surface area while reducing airflow resistance. The gasket seal ensures an airtight,
leak-proof fit against the mounting frame, which is critical for maintaining sterile
environments.
Key
Benefits
- 📏 Compact Design: Depths of 50mm to
150mm make them ideal for ceiling modules and terminal housings.
- 🔒 Leak-Free Integrity: Specialized PU
sealants and high-quality gaskets prevent air bypass.
- 🌬️ Higher Airflow: Mini-pleat configuration provides larger
filtration area for higher wind speeds with less resistance.
Technical Specifications
- 📊 Efficiency: Typically 99.97% to
99.997% @ 0.3 µm (Grades H13 and H14 per EN1822).
- 🧪 Filter Media: High-quality
micro-glass fibre paper.
- 🛠️ Gasket Materials: Neoprene, EPDM,
Silicone, or PU foam mechanical compression seal.
- 🏗️ Frame: Anodized extruded Aluminium, Galvanized Steel (GI), or
Stainless Steel (SS 304).
Common Applications
