HEPA & ULPA filters Filter classes E10 - U15

An outstanding feature of SF HEPA and ULPA filters are the high-quality glass fibre papers in every filter class. The filter media are minipleated and, thanks to this optimum pleat geometry, provide an even air flow combined with minor pressure drops. The HEPA filters are tested in accordance with EN 1822 and are supplied together with a test certificate. SF high efficiency filter panels with metal frames (optionally with grip protection) provide great safety against bacterial and fungal growth. SF HEPA filters with MDF frames (medium-density fibre panel) are non-corroding and simplify disposal, as they are produced without metal parts.
