This HEPA/ULPA filter with ePTFE membrane is designed as an alternative to HEPA/ULPA made of fiberglass. It is widely used as it provides extremely high particulate filtration efficiencies, lower pressure drops and negligible off-gassing, and it is highly resistant to corrosive environment.
1. ePTFE membrane combines ultra-high efficiency with negligible pressure drop 2. Energy savings of more than 30% 3. High resistance to corrosive environments (acids, alkalis, organic substances) 4. Negligible off-gassing properties (boron, sodium, potassium, silicon) 5. Tougher media, more resistance to rough handling in transportation and installation 6. Lower profile, reducing space and weight 7. UL 900 certificated

Perfect Filter Media
Compared with micro-fiberglass media, the ePTFE media provides superior benefits including inert chemical properties, more uniform fiber distribution, smaller fiber diameters and pore size, which reduces resistance with higher filtration performance to achieve substantial energy savings.
Perfect Pleat Design
The ePTFE membrane pack is produced to assure precision in pleat spacing and height, thereby reducing “dead-spots” and promoting consistent and uniform air distribution throughout the filter. The pleat design allows the air to move throughout the entire depth of the filter, utilizing the full cleaning capability of the membrance.
ePTFE pleated pack resistance is a minimum of 30% lower than conventional micro-fiberglass media, a factor contributing to reducing fan energy consumption. The new pleating method using intermittent separators, allows greater substantially more open media area, optimizing pleat pack resistance.
