FILTECH 2023: Hengst focuses on energy-efficient and sustainable filtration

Germany’s Hengst is presenting its full spectrum of filtration systems and filter elements at FILTECH this year with the focus on newly developed energy-efficient and sustainable products.

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

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.

The replaceable filter concept by Hengst is another solution that meets the strict requirements of 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 has been designed as a high-quality lifetime component. When a change is required, only the flat pleated filters including the seals will be replaced – which substantially reduces the amount of waste. The base material for the frame is composed of resource-friendly recycled material, and the packaging offers the additional benefit of being FSC-certified.

Another innovation 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 reduces the consumption of fossil resources and raw materials.

Other highlights at FILTECH include a newly developed Hengst cathode filter for use in fuel cell technologies. 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.

“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,” says Peter Wink, Group Vice President Filtration for Industry and Environment at Hengst.
