Avery Filter Co., Inc.
About
Avery Filter Company, founded in the early 1960s and based in Westwood, New Jersey, is a specialized manufacturer and rebuilder of pressure filtration equipment with over 60 years of industry experience. The company distinguishes itself as the only used equipment dealer focused exclusively on liquid separation and filtration equipment. Avery's flagship products are variable volume membrane filter presses that achieve 50% to 100% higher solids content than conventional fixed-volume presses through membrane squeeze pressures up to 225 psi, delivering reduced cycle times, superior cake washing with pre-squeeze channel elimination, and higher cake solids for maximizing product yield. The company supplies filter plates in polypropylene, stainless steel, aluminum, cast iron, and PVDF, along with membrane plate stack conversion kits that retrofit existing presses with squeeze technology, PLC controls, and safety interlocks. Their filter media division stocks over 75 grades of cellulose filter papers and more than 50 types of filter cloths in polypropylene, polyester, nylon, and cotton — each custom cut and punched to fit Sparkler, Niagara, Star, and Mefiag equipment. Avery also deals in rebuilt and remanufactured equipment including rotary vacuum filters in precoat and scraper discharge configurations, pressure leaf filters, horizontal plate filters, ceramic and stainless steel vacuum nutsche filters, and belt filter presses, along with specialized units from Larox, Fest, Schenk, and Funda. Industries served include commodity and specialty chemicals, pharmaceuticals, food products, clay and ceramic powders, dyes and pigments, and industrial waste dewatering and recycling.
