HEPA Terminal Module

The use of high-efficiency particle stopper (HEPA) filters including pleated packs of High-density glass fibre paper with aluminium or craft paper separators, sealed into a timber or metal frame with urethane, influenced by Cleanroom technology. In Pharmaceutical industry it is required to install HEPA and ULPA filters of H14 – U17Classes. The most penetrable particle size in below classification is more than 0.1µm but less than 0.3µm Integral value Local value Filter class Collection efficiency (%) Penetration (%) ≥0.3µm ≥0.5µm H10 85 12 – – H11 95 5 – – H12 99.5 0.5 – – H13 99.95 0.05 99.75 0.25 H14 99.995 0.005 99.975 0.025 H15 99.9995 0.0005 99.9975 0.0025 H16 99.99995 0.00005 99.99975 0.00025
