HEPA Corporation takes minipleat design one step further than the industry standard with its 5" HEPA ENERGY SAVERŪ filters. Offering greater design flexibility and longer life, these filters are better suited to meeting your velocity, airflow, pressure drop, efficiency and frame size requirements. By upgrading to 5" HEPA ENERGY SAVERŪ filters, both new and existing installations can realize savings of approximately 50% in equipment and energy costs over the industry standard hepa filters. The 5" HEPA ENERGY SAVERŪ advantage: 2000 CFM @ 1.42" w.g. * with a minimum efficiency of 99.97% in a 24"x24" filter. 100 FPM @ 0.22" w.g. in a 24"x24" filter. Upgrade from hepa to ulpa with no additional operating costs and little or no equipment changes. Low energy cost per filter in new or existing cleanroom designs. DOP, PSL, scan and/or laser efficiency tested as required. * Factory tested at 2000 CFM on production filters - not extrapolated from 1000 CFM test flow.
