Hepa And Ulpa Filters
The filter series with hot melt technology is a unique family of mini-pleat HEPA and ULPA filters designed to
meet the demanding airflow and efficiency requirements of the semiconductor, pharmaceutical, biotech,
food processing, and other industries where airborne contaminants must be carefully controlled. These
filters combine the right features to provide optimum efficiency while keeping operating costs to a minimum.
The filter series with knife-edge cell sides was designed specifically for gel seal grid systems. With 2″, 3″, or 4″
deep media packs, the filter design reduces resistance and provides the lowest possible pressure drop. Hot
melt glue beads maintain pleat separation within the pack while allowing a more compact filter depth than
corrugated separators. The media pack is bonded to the sides of the extruded aluminum frame with urethane
adhesive, forming an airtight seal. The filter’s microglass media is water-resistant and fire-retardant.
The filters are scan-tested at 99.99% efficiency with a non-DOP aerosol to ensure they are free from pinhole
leaks. An ULPA (Ultra Low Penetration Air) model is also available, which is additionally laser-tested to
99.9995% at 0.10–0.20 μm.
