Innovations for energy-efficient and sustainable filtration

Hengst Filtration will be providing insights into its entire product range at Filtech 2023.

Münster, January 12, 2023 - Filtration solutions from Hengst Filtration help to clean up the world in numerous application areas. The products are equally in demand in the fields of plant and mechanical engineering, industrial filtration, hydraulics, Life Science and Health Care as well as in the automotive and engine industries. The Münster-based company will be showcasing its entire range of filtration systems and Filter Elements at Filtech in Cologne from February 14 to 16, 2023 (Hall 7, Stand K13).

In line with the trade fair motto "More than just a filtration solution. Energy-efficient and sustainable.", the focus will be on numerous new product developments.

    Energy efficiency and sustainability are among the defining challenges of our time. Based on our many years of filtration expertise and development competence, we can offer forward-looking, application-specific solutions to meet these high demands.

    Sustainable reduction in energy costs

    HEPA filter for cleanroom applications

    A convincing example of energy-optimized filtration is the new HEPA filter for cleanroom applications from Delbag. It is characterized by a particularly low differential pressure and therefore requires around 20 percent lower energy costs compared to conventional HEPA filters. As the energy requirement accounts for around two thirds of the total operating costs, sustainable benefits can be achieved - both economically and ecologically.

    System integration for greater energy efficiency in electrical appliances

    The dust management system for vacuum cleaners is equally geared towards energy efficiency. All components are optimally coordinated with each other in a customized overall concept. The innovative Hengst filter system EASE (Energy Efficiency and Automatic Dust Emptying) for cordless handheld vacuum cleaners or corded upright vacuum cleaners, for example, maximizes suction power and battery life thanks to its high degree of functional integration.

    Sustainable raw materials and technologies

    Innovative filter cartridge concept for household appliances from BSH

    The Filter cartridge concept from Hengst also meets high requirements for sustainable, resource-saving filtration. The solution, which has proven itself many times over in the automotive sector, is now being transferred to electrical appliances for the first time and is being used in series production for vacuum cleaners from BSH Hausgeräte GmbH. The plastic filter cassette is designed as a high-quality, durable component. Only the flat pleated filter, including the gasket, is replaced when necessary - this significantly reduces the volume of waste. Resource-saving recycled material is used as the base material for the frame, and the packaging is also FSC-certified.

    Bio-plastic instead of fossil raw materials

    Another innovation for optimizing theCO2 footprint is Nordic Air Filtration's Filter cartridges for dust collector applications. Here, the previous steel end plates are replaced by the thermoplastic biopolymer polylactide (PLA). The bioplastic thus reduces the need for fossil resources and raw materials.

    Filtration Fuel Cells for fuel cell applications

    Other highlights at Filtech include a newly developed Hengst cathode filter for innovative fuel cell technologies. This is because fuel cell systems will be a key technology for sustainable mobility in the future, particularly in the commercial vehicle sector.

    Thanks to particularly effective filtration of sulphur gases and ammonia, the filtration solution reliably prevents the catalytic converter and membrane of the fuel cell from being damaged by particles and harmful gases.

    Insights at the trade fair stand and in specialist presentations

    Hengst will not only be showcasing innovations for sustainable and energy-efficient filtration at the Filtech trade fair stand, but will also be exploring the topics in greater depth in the form of two specialist presentations:

    • T. Stoffel: "How Eurovent is improving ventilation and industry decision-making" (February 14, 4.45 p.m.)
    • L. Petersen, A. Lawson, J. Niehoff: "Energy-efficient separation of nanoparticles through electrification of air filtration" (February 16, 2.45 p.m.)
