The filter is produced on state-of-the-art production line machin ery that compresses a one-piece channel frame onto the media and retainer. The result is a filter of consistent high quality at acompetitive price. Construction The one-piece channel frame is formed into a wedge which slopes to the center on the upstream side and is flat on the air exit side. The one-piece feature, eliminates problems associated withfour-piece frames, such as broken corners and exposed metaledges. This flat air exit side distinguishes the Modified Channel filters from ordinary pinch frame filters that may be difficult to install/remove and which may not seal well in the filter channel. A notched frame design allows the filters to nest, creating savingsadvantage of approximately 30-35% in warehouse space and freight costs. A double bead of hot melt glue running the full perimeter of the frame is used to bond all components into one tough unit. Thisprocess permits the use of a single metal grid on the air exitside only or no metal grid at all, thus maximizing filter face area to extend service life. Four separate Modified Channel Styles areoffered: EZ Flow: The filtering media is continuous filament spun glass. A resinous bonding agent provides rigidity and resistance to media compression. Ametal media retainer is positioned on the downstream side. Retainer may be either recycled bottle cap or expanded metal, depending on filter size. EZ Flow II : Construction is identical to the EZ Flow Modified Channel, but there is no metal media retainer. Flanders Precisionaire Synthetic: The filtering medium ismade of 100% nonwoven polyester synthetic fibers chemi cally bonded with a fire retardant resin. Because of the synthetic nature of the fiber, the media is extremely resistant to moisture and other environmental extremes. Flanders Precisionaire Synthetic with Metal: Construction is identical to the Flanders Precisionaire Synthetic filter but twith an added metal retainer on the downstream side.
