The Menardi Timeline

1913Menardi was born
1952Menardi developed the first fiberglass finishes and filter bags for high-temperature applications.
1956MikroPul (our sister company) developed the pulse-jet baghouse system.
1957Menardi was innovative in the use of synthetic fiber fabrics for industrial applications including the widely used polypropylene filter cloths for refining bauxite and needled felts for the production of viscose.
1957Along with Portland Cement, Menardi played a key role in the discovery of reverse air cleaning to minimize the wear on fiberglass bags in shaker baghouses.
1958 - 1962Menardi supplied fiberglass filter bags with their silicone finish to carbon black, cement, iron foundries, steel mills, and specialty chemical companies.
1963Menardi makes another break-through, developing what was then known as FLO-BAK® filter bag rings. Today, this method of producing filter bags for reverse air baghouses is a worldwide standard and is most commonly referred to as "anti-collapse rings."
1964Menardi introduced Graf-O-Sil®, a unique finish comprised of graphite, Teflon®, and silicone.
1966MikroPul installed its first pulse-jet baghouse.
1968Menardi developed the Dispos-A-Cap® bag cap. Today this is the standard for attaching fiberglass and other filter media fabric bags to baghouse structures and is widely copied by other suppliers.
1969MikroPul designed the top-load entry pulse-jet baghouse.
1972Menardi worked with E.I. DuPont Company in developing Tuflex®, a 100% Teflon finish for application to fiberglass filtration fabrics.
1973Menardi supplied a utility customer with Tuflex fiberglass filter bags for use on a coal fired boiler application. This was a pivotal point for the utility industry in particulate emission control.
1980Menardi began manufacturing its own quality filtration felt fabrics.
1986Menardi developed aramid with Shield™ finish to meet the needs of medium to high temperature applications.
1987MikroPul designed the Advantaflo™ and Cascadair™ inlet diffusers.
1989Menardi developed ARN-1, an acid resistant finish for aramid fabric.
1990Menardi developed the Mikrotex® product line - expanded PTFE membrane products developed for high efficiency solutions and engineered for difficult applications.
1990Menardi developed 609 Hi-Flo™, a lightweight woven fiberglass fabric and finish for higher efficiency and improved gas flow.
1994MikroPul invented the Pop-Top® design for top-loading pulse-jet filters. This design is a significant time saver in the installation and removal of pulse-jet filters.
1996Menardi developed the SDF® finish as a "tweener" product in performance level between standard fiberglass finishes and expanded PTFE membrane for higher efficiency filtration.
1997Menardi introduced the Mikro-Pleat™ product line of pleated filters and cartridges.
2001Menardi installed a state-of-the-art high speed pleated filter and cartridge production line.
2002Menardi introduced Mikro Boss™ technology, a patented media which prevents collapsing of pleats under operating pressure.
