noticias de la compañía sobre Modular Cleanroom Terminal Filtration : HEPA &ULPA filter

Both filters require EN1822/ISO 14644-1 certification, but ULPA demands stricter MPPS (Most Penetrating Particle Size) testing at 0.1–0.2μm vs. HEPA's 0.3μm. Leak tests (DOP/PAO) and biannual integrity checks are critical, with ULPA systems often incorporating additional validation like thermal sterilization (e.g., 320°C-resistant frames).

While ULPA filters cost 2–3* more than HEPA (e.g., ¥15,000 vs. ¥5,000 for H14), their use in targeted high-risk areas minimizes lifecycle expenses. Modular designs allow hybrid configurations—HEPA for 80% of airflow with ULPA localized at FFUs or pass-through chambers—balancing performance and budget. PTFE-based ULPA filters further reduce long-term costs via 30% energy savings
