| Sewn End Filter Elements
have rugged metal baskets and hand
sewn media that match a design proven for decades. These elements
are constructed entirely from metal and textile media, without
needing any potting material or synthetic end seals. They can endure
services with otherwise difficult chemistry or high temperatures
that molded end elements or some adhesives used in metal ended
filters could not withstand. We start with heavy duty 16 & 20 ga. center cores with 58% open area for lower ÆP. Competitors will often use expanded metal or off grade perf. Large elements get solid steel support rings and welded lift lugs to assist you in handling. We double weld for superior strength. Our standard deck wire is woven to width. Competitors will often use mild steel screen (rusts) with raw cut edges that can poke through the media. When a non-standard width is required, we do something no one else does, we fold it. We preclude the chance for sharp wires to damage the crucial filter media, or even more importantly, your hands! Our radius cut notch ring reliably secures the pleated deck wire assembly to the element core. Others use square cut notch ring that fails. Standard sewn end filters (those with cat#s ending with K5 ) use corrosion inhibited carbon steel cores, epoxy coated deck wire, and high flow 10µ (98%) polyester felt media. For corrosive services, we offer optional 304 or even 316 stainless steels. A wide selection of alternative filter media covers a full spectrum of chemical resistances, with particle retentions down to 1 µ, and service to 700°F. |
