Innovations for energy-efficient and sustainable filtration

Hengst Filtration gives a sneak peak of their entire product range at Filtech 2023.

Münster, January 12, 2023. Used across a wide range of applications, the filtration solutions devised by Hengst do their part in making the world a purer place. The products are uniformly popular in the segments of plant and machine engineering, industrial filtration, hydraulics, life science and health care as well as in the automotive and motor industry. The company from Münster will showcase their entire spectrum of filtration systems and filter elements between February 14th and 16th, 2023 at Filtech in Cologne (Hall 7, Booth K13).

Following the trade show motto "More than just a filtration solution. Energy- efficient and sustainable.", the presentation will focus on a multitude of newly developed products. "Energy efficiency and sustainability rank among the most pressing challenges of our time. Our long years of filtration expertise and development competence have put us in a position to offer pioneering and application-specific solutions that satisfy the highest standards", underlines Peter Wink, Group Vice President Filtration for Industry and Environment.


Substantial savings in energy cost

HEPA filter for clean room applications

A strong example of energy-optimized filtration is the new HEPA filter for clean rooms engineered by Delbag. Distinguished by its particularly low differential pressure, the filter produces energy costs that are roughly 20 percent lower than those caused by conventional HEPA filters. As energy consumption makes up two thirds of the total operating costs, this savings translates to long-term benefits – both from an economic and an ecological standpoint.

System integration for improved energy efficiency in electrical appliances

Energy efficiency is also the main focal point of the dust management system designed for vacuum cleaners. To maximize energy efficiency, all components have been optimized to interact perfectly as part of an overall concept tailored to each customer. As an example, the Hengst filter system EASE (energy efficiency and automatic dust emptying) for cordless handheld vacuum cleaners or corded floor vacuum cleaners maximizes both suction and battery life by delivering a great degree of function integration.


Sustainable raw materials and technologies

Innovative easy-change filter concepts for household appliances made by BSH

The replaceable filter concept by Hengst is another solution that meets the strictest requirements imposed on sustainable and resource-friendly filtration. Tried and tested for a long time in the automotive sector, the solution is now applied in electrical appliances and has been integrated into series-production vacuum cleaners made by BSH Hausgeräte GmbH. The plastic filter cartridge for use in these appliances has been designed as a high-quality lifetime component. When a change is required, only the flat pleated filters including seal will be replaced – which reduces the amounts of waste substantially. The base material for the frame is composed of resource-friendly recycled material, and the packaging offers the additional benefit of being FSC-certified.

Organic plastic takes the place of fossil raw materials

Another innovation that helps optimize the CO2 footprint is the filter cartridge made by Nordic Air Filtration, which is designed for applications in the dust extraction sector. The steel end plates previously used in such products have been substituted with the thermoplastic biopolymer polylactide (PLA). The organic plastic thus reduces the consumption of fossil resources and raw materials.

Filtration for fuel cell applications

Other highlights that will be unveiled at Filtech include a newly developed Hengst cathode filter for use in innovative fuel cell technologies. This is significant as fuel cell systems will arise to the status of a key technology for sustainable mobility - especially in the utility vehicle sector.

Thanks to a highly effective separation of sulfur gas and ammonia, the filtration solution reliably protects the catalytic converter and the membrane of the fuel cell against damage from particles and noxious gases.

Insights at the trade fair booth and in expert lectures

Aside from demonstrating innovations for sustainable and energy-efficient filtration at their Filtech booth, Hengst will also delve deeper into the subject in the context of two expert lectures:

  • T. Stoffel: "How Eurovent is improving ventilation and industry decision-making" (February 14, 4:45pm)
  • L. Petersen, A. Lawson, J. Niehoff: "Energy-efficient separation of nanoparticles through electrification of air filtration" (February 16, 2:45pm)
