Key Advantages

• Top-tier H14 filtration – captures ≥99.995% of particles down to 0.3 microns, ideal for the most stringent cleanliness requirements
• Advanced Gel Seal (in-channel) technology – delivers superior airtight sealing, self-healing properties, and virtually zero risk of air bypass leakage
• Extended size 610 x 915 x 73 mm – larger media area supports high airflow and wide coverage in a single filter unit
• Anodized aluminium profile frame – corrosion-resistant, lightweight, and built for long-term durability
• Dual-sided painted aluminium protection grids – provide maximum mechanical protection for the filter media
• Generous ±10 mm tolerance – allows easy installation even in housings with slight dimensional variations

Applications

This filter is specifically designed for environments demanding the highest level of air purity:

• Air conditioning systems in hospitals, operating theaters, isolation rooms, and medical facilities
• Laboratories for research, pharmaceuticals, and microbiology
• Museums and cultural preservation institutions to safeguard artifacts from airborne contaminants
• Pharmaceutical industry – ensuring sterile production zones free from cross-contamination
• Food & beverage industry – meeting strict international hygiene regulations
• Microelectronics, semiconductor fabrication, and high-class cleanrooms

HEPA Filter H14 with Gel Seal for Ultimate Air Purity & Leak-Proof Performance

The HEPA Filter H14 delivers premium-grade air filtration with ≥99.995% efficiency at 0.3 microns (EN 1822 certified). It excels at removing ultra-fine dust, bacteria, viruses, pollen, and all microscopic contaminants. The in-channel Gel Seal technology makes it the preferred choice for critical applications where even the smallest air bypass is unacceptable.

With an 610 x 915 x 73 mm size, this filter offers significantly more media surface area, making it well-suited for large AHU/FFU systems requiring high airflow capacity. The combination of high-quality microglass fiber media, anodized aluminium profile frame, advanced gel seal, and robust protection grids ensures reliable, long-lasting performance in sterile and controlled environments.

Recommended Filtration Stage Sequence in HVAC / Cleanroom Systems

In HVAC or cleanroom setups, HEPA H14 is positioned as the final filtration stage to achieve maximum purity. The recommended sequence is:

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

This staged approach optimizes energy efficiency, extends HEPA service life, and maintains overall system performance.

How to Install Gel Seal HEPA Filter

1. Ensure the housing, plenum, or terminal is completely clean and free of dust before installation.
2. Check the knife-edge (sealing blade) on the housing – it must be clean and undamaged.
3. Carefully remove the old filter (wear gloves and proper protective equipment).
4. Install the new filter: align the gel seal channel to the downstream side, gently lower until the knife-edge enters the gel. The gel will form an automatic, self-healing seal.
5. Confirm the filter is seated flat and square – do not force it.
6. Perform a leak test (DOP / PAO) immediately after installation to verify zero leakage. Note: Installation should be carried out by trained personnel in a clean environment.

When to Replace the HEPA Filter

Replace the filter when:

• Final pressure drop reaches or exceeds 600 Pa (typically 1.5–2× initial pressure drop)
• Differential pressure increases significantly → causing higher fan load and energy consumption
• Leak test (DOP/PAO) fails (mandatory testing every 6–12 months per ISO/GMP standards)
• Average service life of 1–3 years is reached (depending on dust load, pre-filter quality, and operating conditions)

Monitor differential pressure regularly. Replace earlier if air quality or energy efficiency is a priority.
