Camfil Farr, world leader in air filtration for business and industry, has introduced a new filter configuration that radically changes how air is cleaned in a commercial or institutional environment. The product has significant advantages in terms of immediate reductions in facility fixed costs. Durafil ES is an easy drop-in replacement for any standard V-shaped filter. But the similarities end there. Four characteristics distinguish Durafil ES filters. First, this filter technology reduces the total energy consumed by the HVAC system by 20-35% compared to any competitive (V-style) product. This savings is produced by a patented radial inlet and outlet, which generates a much lower pressure drop profile. The significance is considerable: there is 30% more open area on the filter inlet of the Durafil ES, and 60% more on the outlet, compared to conventional V-style filters. This greater open area is key to the lower pressure drop condition. Camfil Farr has also developed a new height-to-pleat spacing configuration. Using the same amount of media, with more pleats per inch, the result is greater active filter area. Durafil ES uses a fine fiber Energy Star media. This media maintains its high efficiency performance throughout its service life. This is in marked contrast to electrostatically charged, synthetic media, whose efficiency drops quickly in use. Finally, Durafil ES is rated “five star” by the Energy Cost Index (ECI) Program. Based on a scale of 5, the Energy cost index indicates what a filter costs over its service life. A top 5-star rating indicates the filter is the most energy-efficient, and longest-lasting, available. One of the construction features unique to the Durafil ES is a built-in prefilter spacer section. This feature benefits installations where a prefilter is mounted directly to the face of the filter. In these instances, the spacer eliminates airflow blockage, and the high pressure drop that results. This problem is universal with traditional V-style filters, and produces an energy penalty of $50 per filter per year. The advanced engineering of the Durafil ES eliminates this issue, and this expense, immediately reducing
