High efficiency in filtration .
Leak proof sealing thus no air leakage.
Low initial and final pressure drop.
Separator – Corrugated Aluminum Foils Helps to Stabilizes pleats throughout its life.
Hemmed edges of Aluminum separators reduces possible pleat damages.
High Mechanical strength.
Deep Pleat HEPA Filter Grade to EN1822 media adopts the ultra-thin glass fiber, the hot-melt glue spacing each pleats in regular so that achieve high dust volume. Pleats are equally spaced to maintain uniform air distribution.
Applications of Deep Pleat HEPA Filters
Deep Pleat HEPA Filters are used to achieve the highest levels of fine air filtration and air quality, up to H14 to EN1822. HEPA Filters are used in operating theaters, electronics, pharmaceuticals, research facilities and micro biological laboratories.
Construction of HEPA Filters
HEPA filters Deep Pleated are constructed out of a glass fibre paper pack, which is pleated to the depth of the filter and spaced with pleated aluminium or kraft paper spacers. The glass fibre paper pack secured within a metal or wooden case, with gasket available for the ‘air on’ side to ensure a tight seal.
