Extended Surface Bag Filters

FEATURES: Glasfloss Excel and Purapak extended surface bag filters offer excellent performance and durability for applications requiring medium to high ASHRAE efficiencies. The Excel bag filter features 100% synthetic media and offers excellent value and performance for most applications. The Purapak bag filter features ultra-fine fiberglass media and is ideal for applications where fiberglass is specified. Both the Excel and Purapak bag filters feature an exclusive internal header design, which adds strength to the filters and virtually eliminates "racking" during installation. ASHRAE 52.2 test method performance ranges include MERV 9 (40-45%), MERV 11 (60-65%), MERV 13 (80-85%) and MERV 14-15 (90-95%). Glasfloss Excel and Purapak bag filters are available in most standard and specialsize face dimensions in standard and special depths.

CONSTRUCTION: The Excel bag filter is constructed with 100% synthetic media. The Purapak bag filter is constructed with ultra-fine fiberglass media. Individual pockets are formed by span stitching down the length of the pockets, which allows for maximum utilization of the media. Each pocket is fastened to the next with an "L" shaped support rib, preventing the pocket from pulling free under adverse conditions. The entire assembly is encased in a galvanized steel frame to prevent racking during installation.

Glasfloss Excel and Purapak bag filters provide dependable performance in a wide range of commercial and industrial applications. The exclusive Glasfloss internal header design ensures maximum durability and ease of installation in hospitals, manufacturing plants, office buildings and many other applications.
