The Alpha 95 is rated MERV 17 per ASHRAE Standard 52.2. Alpha 95 filters are identical in design and construction to the Alpha Cell HEPA filters except that the media is 95% efficient on 0.30 micrometer particles. Installation Considerations Alpha 95 filters should be installed in Flanders leak tight Alpha HEPA frames or Surelock Side Access HEPA Housings on the positive-pressure side of the system fan to prevent air bypass. Sureaire diffuser sections, air mixing baffles or long transitions should be used if the bank is close to the fan. Installation of Flanders ASHRAE efficiency prefilters upstream of the fan is recommended to ensure economical Alpha 95 filter life. Important Features Standard Alpha 95 filters have 1.7 times the cfm capacity of standard Alpha Cell 99.97% DOP HEPA filters at the same clean pressure drop. They are normally rated at 500 fpm so that filter banks with 95% DOP filters can be sized the same as ASHRAE-rated filter banks. Typical applications for Alpha 95 include: • Hospitals • Biomedical • Pharmaceutical • Biotechnology • Genetic Research • Universities • Laboratories • Food Processing • Photo Processing • Semiconductor Fabrication • Industrial Processing Systems Product • Minimum efficiency is 95% on 0.30 micrometer particles. • Manufactured in a variety of wood and metal frame types. • Available with a media pack with aluminum separators or with a separatorless pack. • Available in a variety of sizes with either a gasket or gel seal.

To make a Separator Style filter, the media is folded over corrugated aluminum separators with hemmed edges to separate the pleats in the filter pack. Flanders manufactures its own filter media, enabling it to develop a unique manufacturing process for the production of Pureform Separatorless 95% DOP filters. In one manufacturing operation, Flanders produces a self-supporting and self-separating Pureform Media Pack. The Pureform filter offers many advantages over conventional Separator Style 95% DOP Filters: • Increased usable media area affords longer service life andhigher dust holding capacity • Maximum utilization of the media • Can handle some harsh environments which may attackaluminum separators • Media pack can be incinerated • Media is 28 mils, significantly thicker than conventional media used in Separator Style 95 DOP filter (15 mil) • Pureform has 25% more media area than conventional style. • Ideal for heavy loading applications such as oil mist.
