H&V partners with Superior Felt & Filtration to bring Trupor® to global markets

Comments Off on H&V partners with Superior Felt & Filtration to bring Trupor® to global markets

EAST WALPOLE, Mass., August 25, 2021 – Hollingsworth & Vose has chosen Superior Felt & Filtration to distribute H&V’s Trupor®, a novel microporous filter media solution. Trupor® enables best-in-class flow rates and delivers membrane reliability via patented microporous filtration media. Microfiltration makes water cleaner, bioprocess products safer, semiconductor products cheaper and industrial processes run longer. Industries depend on microfiltration processes to develop new products and ensure consistent delivery of essential products.

“Microfiltration is an important area of process liquids, and H&V is excited about having a product available for an area with so much potential and growth,” said Fred Lybrand, global marketing director of process liquids for H&V. “We have partnered with Superior before on our Technostat® product family, which has been very successful. Superior is an important partner for H&V.”

“The microfiltration market has established grades and materials that it depends on – H&V’s Trupor® is made with 100% Nylon and is available now as 0.45 micron and 0.65 micron materials,” said Dr. Ping Hao, Technical Nonwoven Product Manager with Superior. “The combination of industry standard materials and grades and Superior’s customer focus and converting capabilities make a compelling case for anyone working with membranes to try Trupor®.”

Trupor® enables enhanced flow compared to traditional membranes, improving the ability to filter novel fluid streams. Its composite structure and superior pore size uniformity deliver consistent and reliable results in the key performance characteristics required by the analytical and diagnostic markets. In most cases, the thin formation of this media offers interchangeable equivalency to its cast film counterparts while delivering performance enhancement both to existing and new process streams.

Superior Felt & Filtration is a global distributor based in McHenry, Illinois, that offers value-added converting, including collating, slitting, pleating and die cutting. The company has previously partnered with H&V for over a decade distributing and fabricating Technostat®, an electrostatic submicron filter media for high-efficiency air applications.

PIUS Project: “Energy Saving in the Production of Compressed Air” is funded by the European Fund for Regional Development

Comments Off on PIUS Project: “Energy Saving in the Production of Compressed Air” is funded by the European Fund for Regional Development

The PIUS program is dedicated to companies of all sizes that are located in Hessian, Germany for supporting research and development projects towards technical solutions for reducing CO2 emissions. The program is lead by the Hessian Ministry for Economy, Energy, Transportation and Regional Development and is funded by the European Union (EFRE; “European Fund for Regional Development”).

The aim of this project comprises the production of compressed air under energy-efficient and climate-friendly conditions in order to save CO2 emissions. Compressed air is part of everyday life and is used in a wide range of tasks in various processes, buildings, vehicles, tools, etc. due to its many advantages (light, wear-free, sterile if necessary, residue-free, cost-effective). The technical production of compressed air by means of compressors in which rapidly rotating compressor screws are lubricated by oils is
widely used. The compressed air produced in this way contains a fine oil mist with particle size distributions in the sub-micrometer to micrometer range, which is collected and removed (or returned to the compressor). This process step requires coalescing filters through which different purity levels of compressed air can be accessed. The highest purity level is currently only achieved by fine particle separators, which, due to their design, result in a high pressure increase and correspondingly high energy consumption during generation.

Our focus in the PIUS project therefore is the development of compressed air de-oiling filters with outstanding separation performance and at the same time low pressure drop, in order to contribute with the filter medium to energy savings in the production of compressed air.
