“Cerex Advanced Fabrics’ spunbond nylon fabrics provide filter producers with a thinner, stronger and more uniform backing substrate that can withstand high temperatures, system pulsations and resistance to chemical attack,” said Jim Walker, president and CEO, Cerex. “Nylon allows filter designs with more pleats providing more filter surface area, which reduces pressure drop and increases dust holding capacity, as well as provides excellent durability for today’s longer service intervals.”
Meltblown fabrics are produced in quite large volumes as roll stock, and are found in both air and several liquid filtration products because of their high dirt hold capacity. Over the past 25 years, meltblown liquid cartridges — also known as spray spun cartridges — where fibers are deposited on a rotating mandrel akin to a lathe and finished into 3-inch-diameter by 10-inches long cartridges in a single-step process have become more common place. Meltblown cartridges bypass the use of roll goods and tend to be lower cost because of their efficient manufacturing process.
Houston-based Filtration Technology Corp. (FTC) produces Platinum filters capable of holding extremely large quantities of contaminate using nonwoven fabrics. “FTC supplies liquid filters in many configurations, but none compare to our Platinum Series filters, which can retain up to several hundred pounds of contaminant,” said Chris Wallace, vice president, FTC. “The unique pleat pattern in our patented Platinum technology maximizes the media surface area in a pressure vessel resulting in lower flux rates and higher contaminant loading capacity per filter cartridge. The Platinum technology provides our customers with longer on line life which translates to lower direct filtration costs, lower maintenance costs and minimal down time. Another feature of this technology is the flexibility to offer the technology to a broad range of applications and markets, since we can use any nonwoven or wetlaid fabric in this unique pleat pattern.”
