• Endless polyurethane gasket ensures a reliable, leak-free seal
• Dual-sided painted aluminium protection grids protect the media during handling and operation
• Easy integration into standard AHU, FFU, and terminal HEPA housings

Applications

This filter is designed for environments requiring the highest level of air cleanliness:

• Air conditioning systems in hospitals, operating theaters, isolation rooms, and healthcare facilities
• Research, pharmaceutical, and microbiology laboratories
• Museums and cultural institutions for artifact protection from airborne contaminants
• Pharmaceutical industry – sterile production zones and contamination control
• Food & beverage processing – strict hygiene and regulatory compliance
• Microelectronics, semiconductors, and high-ISO cleanrooms

HEPA Filter H14 Compact High Efficiency for Critical Air Purity

The HEPA Filter H14 provides premium grade air filtration with ≥99.995% efficiency at 0.3 microns (EN 1822 certified), effectively removing ultra fine dust, bacteria, viruses, pollen, and microscopic contaminants. This compact model (305 x 610 x 66 mm) is part of the HFN Series and is perfect for applications where space is limited or where multiple smaller filters are preferred for better airflow distribution.

Featuring premium microglass fiber media, an anodized aluminum frame, endless polyurethane gasket, and protective grids, it delivers reliable, leak-free performance in sterile and controlled environments. The compact size makes it highly versatile for modular cleanroom designs, mini FFU units, or retrofit projects.

Filtration Stage Sequence in HVAC / Cleanroom Systems In typical HVAC or cleanroom setups, the HEPA H14 is installed as the final filtration stage to achieve maximum purity. Recommended sequence:

1. Pre-filter (G4) – captures large particles and coarse dust, protecting downstream filters and extending their life
2. Medium / Secondary filter (F7 / F8 / F9) – traps medium and fine particles, reducing the load on the HEPA
3. HEPA Filter H14 – final stage, captures ultra-fine particles, bacteria, and viruses

This staged approach maximizes HEPA lifespan, reduces energy consumption, and maintains system efficiency.

How to Install

1. Ensure the housing / plenum is clean and free of dust before installation.
2. Check the sealing surface (knife-edge or channel) for cleanliness and no damage.
3. Remove the old filter carefully (use gloves and PPE).
4. Insert the new filter: align the gasket side correctly (upstream/downstream as marked), press gently until fully seated.
5. Verify the filter is level and properly sealed.
6. Perform a leak test (DOP / PAO scan) to confirm integrity. Note: Installation should be done by trained personnel in a controlled environment.

When to Replace the HEPA Filter

Replace when:

• Final pressure drop reaches or exceeds 600 Pa (typically 1.5–2× initial pressure drop)
• Significant increase in differential pressure → higher fan load and energy use
• Leak test fails (test every 6–12 months per ISO/GMP requirements)
• Typical lifespan 1–3 years (depending on dust load, pre-filter quality, and environment)

Monitor pressure drop regularly; replace proactively if air quality or energy efficiency is critical.
