Press release

FILTER FÜRS LEBEN

Filtration ist eine Schlüsseltechnologie für einen sauberen Planeten: Auf der FILTECH 2023 präsentieren alle Unternehmensbereiche von MANN+HUMMEL Lösungen für saubere Mobilität, saubere Luft, sauberes Wasser unter dem Motto ‚Leadership in Filtration for Cleaner Mobility, Cleaner Air, Cleaner Water, Cleaner Industry‘.

Saubere Mobilität

MANN+HUMMEL zeigt seine Medienkompetenz in der Filtration von Luft, Kabinenluft, Öl und Kraftstoff für Fahrzeuge mit Verbrennungsmotor und für Fahrzeuge mit alternativen Antrieben. Ein Highlight sind Medien für Innenraumfilter für reine und saubere Luft in Fahrzeugen. Der Einsatz einer Nanofaserschicht in Filtermedien erhöht die mechanische Abscheidung - so bleibt die Leistung der Filter über ihre Lebensdauer konstant hoch. PM1 und ultrafeine Partikel, die aufgrund ihrer Größe ernsthafte Gesundheitsgefahren verursachen können, werden durch Nanofaser-Filtermedien effektiv aus der Luft entfernt. Diese Entwicklung schafft Synergien in anderen Anwendungen, so zum Beispiel setzt MANN+HUMMEL diese Medien auch für die Innenraumfiltration in Gebäuden ein.

Saubere Luft

Unter dem Motto „Cleaner Air“ präsentiert MANN+HUMMEL seine Lösungen für saubere Luft zum Schutz von Menschen, Prozessen und der Umwelt. Hier präsentieren sich MANN+HUMMEL Life Science & Environment aus Sprockhövel und MANN+HUMMEL Molecular GmbH aus Gefrees. Gemeinsam werden Lösungen für Reinräume und Gebäude gegen partikuläre (z.B. Feinstaub) und molekulare (toxische oder korrosive Gase, Lösungsmittel, unangenehme Gerüche) Verunreinigungen in der Luft präsentiert.

Ein Produktschwerpunkt in Zeiten hoher Energiekosten sind die Luftfilterlösungen mit A+ Energie-Rating nach Eurovent 4/21, die Gebäudebetreibern erlauben, Energiekosten zu senken. Ein Beispiel aus dem MANN+HUMMEL Programm: ein Wechsel von einem D klassifizierten Taschenfilter Airpocket Select ePM1 65% auf einen Airpocket Eco ePM1 65% mit A+ Rating ermöglicht eine Energieeinsparung von 1241 kWh/a und eine Senkung des CO2 Fußabdrucks um 262 Kilogramm pro Jahr. MANN+HUMMEL bietet mehr A+ und A klassifizierte Filtertypen als jeder andere Hersteller im Markt.

Für die Adsorption von molekularen Schadgasen und flüchtigen organischen Verbindungen präsentiert MANN+HUMMEL eine große Vielfalt an hocheffizienten adsorptiven Filtermedien und Filter auf der Basis von Aktivkohle, Molekularsieben und Ionenaustauschharzen.

Des Weiteren zeigt MANN+HUMMEL seine OurAir Serie. Dank ihrer mit ePTFE Medien ausgestatteten H14 Luftfilter sind die Luftreiniger ein wichtiger Baustein im Kampf gegen zahlreiche Virusinfektionen – egal ob es sich dabei um Corona, Influenza oder andere Infekte handelt. Neu sind optional verfügbare Aktivkohle- und FreciousComfort-Filter für die flexibel einsetzbaren Geräte. Die zusätzlich damit ausgestatteten Luftreiniger fangen damit nicht nur 99,995 Prozent der Viren, Bakterien, Mikroorganismen und Allergene aus der Luft, sondern reduzieren zudem schlechte Gerüche sowie Schad- und Reizgase. Dies ist vor allem für Pflege- und Altenheime eine Bereicherung, da sie neben dem Wohlbefinden der Bewohner auch das Arbeitsumfeld für das Pflegepersonal enorm verbessern. Aber auch in Restaurants und Fitnessstudios kann man damit unliebsame Gerüche beseitigen. In Zeiten von hohen Infektionszahlen und gleichzeitig explodierenden Energiekosten bieten sich die Luftreiniger als effektivere Maßnahme zur Reduzierung des Infektionsrisikos in privaten und öffentlichen Gebäuden ganz besonders an, denn sie verbrauchen wesentlich weniger Energie als zum Aufheizen der Räume nach dem Lüften benötigt wird. Die Luftreiniger arbeiten schnell und geräuscharm und sind in drei Größen erhältlich, passend für Räume von 40 bis 200 Quadratmeter.

Sauberes Wasser

Die MANN+HUMMEL Schwerpunkte sind Membranlösungen für die Filtration von Abwasser, Trinkwasser, Prozessflüssigkeiten und für die Meerwasserentsalzung.

MANN+HUMMEL Water & Fluid Solutions präsentiert den Membranbioreaktor (MBR) BIO-CEL® M+. Er ist die bisher vielseitigste Lösung von MANN+HUMMEL für Kläranlagen. Der BIO-CEL M+ ist für den Einsatz in mobilen und mittelgroßen Kläranlagen optimiert und passt perfekt in einen High-Cube-Container, der den Bau von äußerst kompakten dezentralen Kläranlagen ermöglicht. Eine Einheit kann das Abwasser von bis zu 480 Einwohnerwerten (EW) pro Tag reinigen, was dem Abwasser von etwa 115 Haushalten entspricht.

BIO-CEL M+ ist mit der Hochleistungs-Ultrafiltrationsmembran BIO-CEL UV400T ausgestattet, die speziell für den Einsatz in Membranbioreaktoren entwickelt und optimiert wurde und eine höhere Langlebigkeit, Unterstützung und Leistung bietet und verhindert, dass antibiotikaresistente Bakterien in die aquatische Umwelt gelangen.

Des Weiteren präsentiert die MANN+HUMMEL-Gesellschaft Seccua als weltweit führendes Unternehmen im Bereich der Trinkwasseraufbereitung für Privathaushalte, öffentliche Gebäude, Gewerbebetriebe und Kommunen den Wasserfilter UrSpring für Ein- und Mehrfamilienhäuser. Der UrSpring entfernt nicht nur Partikel wie Mikroplastik, Rost und Trübungen, sondern auch bis zu 99,99999 Prozent der Bakterien und Parasiten und bis zu 99,99 Prozent der Viren zuverlässig aus dem Trinkwasser. Seccua will Menschen weltweit Zugang zu sauberem, hygienisch einwandfreiem Trinkwasser ermöglichen.

FILTERS FOR LIFE

MANN+HUMMEL presents solutions for cleaner mobility, cleaner air, cleaner water and cleaner industry.

Filtration is a key technology for a cleaner planet: At FILTECH 2023 all of MANN+HUMMEL’s business units will present solutions for cleaner mobility, cleaner air, cleaner water and cleaner industry under the motto “Leadership in Filtration for Cleaner Mobility, Cleaner Air, Cleaner Water, Cleaner Industry”.

Cleaner Mobility

MANN+HUMMEL will be showcasing its media expertise in the filtration of air, cabin air, oil, fuel for vehicles with internal combustion engines and for vehicles with alternative drives. One of many highlights is our media for cabin air filters for pure and clean air in vehicles. The use of a nanofiber layer in filter media increases mechanical separation – thus keeping the performance of the filters consistently high over their lifetime. PM1 and ultrafine particles, which can cause serious health hazards due to their size, are effectively removed from the air by nanofiber filter media. This development creates synergies in other applications, for example, we also use this technology for indoor air filtration in buildings.

Cleaner Air

Under the motto "Cleaner Air", MANN+HUMMEL will be presenting its solutions for cleaner air used to protect people, processes, and the environment.

MANN+HUMMEL Life Science & Environment from Sprockhövel and MANN+HUMMEL Molecular GmbH from Gefrees will be presenting solutions for cleanrooms and buildings against particulate (e.g. fine dust) and molecular (e.g. toxic or corrosive gases, solvents, unpleasant odors) contaminants in the air.

In times of high energy costs an important highlight are air filter solutions for HVAC applications with A+ energy rating, which allow building operators to reduce energy costs. An example from the MANN+HUMMEL range: a change from a D rated Airpocket Select ePM1 65% pocket filter according to Eurovent 4/21 to an A+ rated Airpocket Eco ePM1 65% allows an energy saving of 1241 kWh/a and a reduction of the CO2 footprint by 262 kg per year. MANN+HUMMEL offers more A+ and A rated filter types than anyone else in the market.

For the adsorption of molecular pollutant gases and volatile organic compounds, MANN+HUMMEL presents a wide variety of highly efficient adsorptive filter media and filters based on activated carbon, molecular sieves and ion exchange resins.

Furthermore, we will show our OurAir series of air purifiers. Thanks to their H14 air filters equipped with ePTFE media, they are an important building block in the fight against numerous viral infections - whether corona, influenza or other infections. New features include optionally available activated carbon and FreciousComfort filters for the flexibly deployable units. The air purifiers additionally equipped with these not only catch 99.995 percent of viruses, bacteria, microorganisms and allergens from the air, but also reduce bad odors as well as harmful and irritant gases. This is particularly beneficial for nursing homes and homes for the elderly, as they not only improve the well-being of the residents, but also the working environment for the nursing staff. But it can also be used to easily eliminate unpleasant odors in restaurants and fitness studios. In times of high infection rates and at the same time exploding energy costs, air purifiers are particularly suitable as an effective measure to reduce the risk of infection in private and public buildings, because they consume much less energy than is needed to heat up the rooms after ventilation. The air purifiers work quickly and quietly and are available in three sizes, suitable for rooms from 40 - 200 m².

Cleaner Water

MANN+HUMMEL focuses on membrane solutions for the filtration of wastewater, drinking water, process fluids and for seawater desalination.

MANN+HUMMEL Water & Fluid Solutions presents the membrane bioreactor (MBR) BIO-CEL® M+. It is MANN+HUMMEL's most versatile solution for wastewater treatment plants to date. BIO-CEL M+ is optimized for use in mobile and medium-sized wastewater treatment plants, and perfectly fits into a High Cube container, which allows the construction of extremely compact decentralized wastewater treatment plants. One unit can treat the wastewater of up to 480 population equivalent (PE) per day, corresponding to the wastewater of about 115 households.

BIO-CEL M+ features the high-performance BIO-CEL UV400T ultrafiltration membrane – specifically developed and optimized for use in membrane bioreactors, offering greater longevity, support and performance – which prevents antibiotic-resistant bacteria from entering the aquatic environment.

Furthermore, MANN+HUMMEL's Seccua company, a world leader in the field of drinking water treatment for private households, public buildings, commercial enterprises and municipalities, will present the UrSpring water filter for single- and multi-family homes. The UrSpring water filter not only reliably removes particles such as microplastics, rust, and turbidity, but also up to 99.99999% of bacteria and parasites and up to 99.99% of viruses from drinking water. Seccua aims to give people worldwide access to clean, hygienic drinking water.

IoT Solutions for Cleaner Mobility, Cleaner Air, Cleaner Water

The MANN+HUMMEL expertise in filtration combined with digital solutions creates more efficiency and value for customers. Examples include solutions such as qlair for monitoring air quality in buildings, Senzit for indicating the status of air filters in construction and agricultural machinery, and Streametric for monitoring the membrane in wastewater treatment plants. Thanks to these intelligent MANN+HUMMEL systems, customers can work in a more resource-conserving and energy-efficient way and increase their productivity.

MANN+HUMMEL and the M-Filter Group, one of the largest filter manufacturers in Northern and Eastern Europe, will be joining forces. Products and solutions from both companies can be found at the MANN+HUMMEL booth (Hall 8, Booth C11) and at the M-Filter booth (Hall 7, Booth K8).

Conference Presentation/s

Reducing the carbon footprint of filter elements with design, process and material optimizations by means of life cycle assessments (LCA)

L. Spelter*, M. Hirt, C. Oprisch, T. Müller, MANN+HUMMEL GmbH, Germany; S. Arora, MANN+HUMMEL USA INC., USA; J. Zenner, MANN+HUMMEL FRANCE S.A.S., France

Conference Session: F01 - Sustainable Filter Elements and Media - 2023-02-15 - 10:45

The European Commission has defined a climate and energy framework to reduce the greenhouse gas emissions within the running decade significantly and to reach climate-neutrality by 2050. Specific targets have been set for 2030: at least a cut of 40 % of greenhouse gas emissions is required (compared to 1990 levels) and a share of 32 % of renewable energies is demanded.

For reducing the greenhouse gas emissions of a company, it is necessary to understand the different contributing factors within the e.g. production but as well of the supply chain and later usage of the products. The life cycle assessment (LCA) is a method to determine these effects of a product on the environment. The LCA may further include e.g. water footprint and social impacts. The emissions are generally classified into scope 1, 2 and 3. Scope 1 are emissions that are directly caused by the company producing the part such as e.g. gas used to heat ovens. Scope 2 are emissions that are caused by the energy that is used but produced externally such as electrical energy taken from a grid. All emissions caused outside the company but that are affecting the carbon footprint (CFP) of the product are scope 3, these are e.g. the carbon footprint of purchased parts or the usage of the product by the customer.

For a filter element the dominating contributing factors are scope 1 and 3, with a major contribution by scope 3. The production of filter media and other raw materials such as polyol and plastics, that are used for sealings or as end plates, are the main drivers for the carbon footprint of a filter element. Thus, a very important aspect is the input data quality to determine scope 3.

In this contribution we will show the LCA for exemplary filter elements and identify the main influencing parameters on the CO2 footprint of these products. A specific focus will be put on the impact of the filter media comparing synthetic vs. cellulose materials...

On the road towards sustainable filtration - Aspects of automotive filter element recycling and disposal

T. Müller*, L. Spelter, F. Keller, MANN+HUMMEL GmbH, Ludwigsburg, Germany

Conference Session: F01 - Sustainable Filter Elements and Media - 2023-02-15 - 10:45

Sustainability aspects are rapidly gaining importance in the automotive industry. This development is driven by the evolving legal framework (e.g. the European Green Deal), end-customer awareness and also by sustainability roadmaps of vehicle manufacturers (OEMs) and their suppliers. The public focus is on CO2 emissions and the ensuing technology shift. However, a transition from today’s (mostly) linear economy towards circular economy is necessary to decouple economic growth from the extraction and use of natural resources [1] as well as a prerequisite for climate neutrality [2].

Figures like the global plastic recycling rate of only 9% for 2019 [3] versus 49% landfill and 22% mismanaged & uncollected plastic waste, respectively, signify that there are still major challenges ahead in the pursuit of “closing the loop”. The related technical, economic and political transition will also drastically affect the filtration industry. The way filter systems and elements are designed, produced, used and disposed of will change significantly over the next 10 to 20 years.

The aim of the present paper is to provide an overview of the key legal, technical and economic aspects of en-of-life treatment of filter elements. We present the current state of the art of filter element disposal and recycling as well as the regulatory framework in the EU. Also, we share insights into challenges and controversies the automotive filtration industry will be facing on its road to circular economy...

Smart filter element development – Applied machine learning for optimized element layouts

T. Gose*, C. Schulz, F. Keller, J. Ziegler, MANN+HUMMEL GmbH; C. Hitzke , S. Zöllner, MANN+HUMMEL Innenraumfilter GmbH & Co. KG, Germany

Conference Session: F02 - Smart Filter Element Development and Production - 2023-02-15 - 13:00

In recent years the importance of data and its’ interpretation has been grown significantly in development processes. Modern methods of Data Sciences enable developers to discover hidden insights in existing datasets or to create new datasets well suited for machine learning. Emerging “data lake” structures can consist of measurement data as well as simulation data or even mixed data from various sources as long as it adds up to the overall knowledge.1

The present talk will discuss challenges in the application of machine learning for optimized filter element layouts.2,3 The goal is to enable developers to find optimal filter designs within seconds instead of hours or days. The optimal filter element design needs to consider the design space and customer specifications, amongst others. Looking on the workflow, the seamless integration of this novel design approach into the whole development process is a core requirement.

The goal of the approach is to maximize the use of the results of a multi-parameter optimization by providing these in an easy and explorative way to the developer being the domain expert.4 This combines challenges of different disciplines as besides model quality also user experience and conformity to the matured automotive development processes need to be satisfied.5 From a technical point of view the mentioned multi-parameter optimization is the backbone of the tool shown in the talk. The optimization parameter can vary and e.g. be pressure drop, dust holding capacity or media area, amongst others.

Model quality strongly depends on the input data quality and the covered parameter range. “Much data” does not necessarily mean sufficient data for machine learning...

From virtual production to real filter media samples

F. J. Hahn*, T. Gose, L. Spelter, K. Riedinger, F. Keller, MANN+HUMMEL GmbH; A. Schmeißer, W. Arne, R. Wegener, Fraunhofer Institute for Industrial Mathematics (ITWM), Germany

Conference Session: F02 - Smart Filter Element Development and Production - 2023-02-15 - 13:00

The emission of fine dust from industrial processes and traffic poses a threat to public health as well as contamination-sensitive manufacturing technology and clean rooms. This necessitates the provision of clean indoor air and therefore requires highly efficient air filter media. Considering the rise in energy cost and the requirement of worldwide CO2 reduction the energy consumption of air filters becomes increasingly relevant. Developing filter media featuring both highest levels of filtration efficiency and lowest possible pressure drop represents an optimization challenge, as both design goals are conflicting.

To tackle such challenges, virtual filter media development has proven to be a valuable tool. In a simulation driven development loop virtual material prototypes of filter media can be specifically designed to yield optimal performance for individual applications. Commonly, these virtual material models are based on a set of statistical parameters describing the structure of fibrous media. However, the producibility of the virtual material structure in a real world production process is not inherently accounted for. Thus, the realization of virtually predicted optimal filter media prototypes requires extensive validation in trial runs and may sometimes not be achievable.

Within the scope of a publicly funded research project we address this limitation by means of a novel, holistic concept for virtual filter media development at the example of spunblown filter media. In our approach, the conventional parametric material model is substituted by a physical simulation model of the media production process. Hereby, the influence of relevant process parameters on the properties of the resulting media structure is directly captured within the virtual material model.

The adherence of the virtual material model to the production process is a key factor for the transferability of virtually predicted filter media designs to real world production. Therefore...

Simulation and characterization of deformed filter media on the fiber level

K.M. Höss*, F. Keller, C. Schulz, MANN+HUMMEL GmbH; S. Schmauder, University of Stuttgart, Germany

Conference Session: F05 - Media Deformation - Modelling and Simulation - 2023-02-16 - 10:45

Dust holding capacity, filtration efficiency, and pressure drop are the main parameters used to measure the filtration performance of flat filter media [1]. These parameters directly depend on the properties of the microstructured fiber network, such as the local pore distribution, fiber diameter distribution, or fiber surface distribution, amongst others. Filtration simulations with selectively modified microstructural properties can help to determine new structures with optimized filtration performance [2]. However, the effective mechanical properties of the new fiber network are unknown at this point in the filter media design process. In order to achieve the required active filtration area in the given design space, it is often necessary to pleat the filter media. The processing into the finished filter bellows places particular demands on the mechanical deformation behavior. Furthermore, the processing itself alters the microstructural properties of the fiber network and, thus, influences the resulting filtration performance.

Therefore, the ability to predict these anisotropic mechanical properties of a microstructural fiber network is crucial for assessing the processability of the new microstructural designs. Mechanical microstructure simulations can help not only to estimate the highly anisotropic elastic-plastic material behavior of these fiber networks but also help to estimate the change in filtration performance based on the modified fiber network. The software GeoDict serves as a virtual laboratory to characterize these fiber networks and to determine their mechanical properties in all three spatial directions under tensile, compressive, shear, or even bending loads.

This presentation introduces a microstructural simulation model for predicting the three-dimensional elastic-plastic behavior of synthetic fiber networks...

Emissions from gasoline engines and brakes of commercial or municipal vehicles as well as by metro or train contribute to health problems and premature deaths. These existing vehicles will continue populating the roads for the next decades emitting PM10/PM2.5 exhaust particles and toxic secondary emissions. For immediate reduction, retrofit filtration solutions for tailpipe and brake wear emissions must be brought to the market. Timing is crucial as retrofits are transition technologies until full electrification of Europe’s transport fleet. But even beyond, brake retrofits may still play an important role in the electrified fleet.

AeroSolfd, a Horizon Europe Innovation Action, addresses quick wins in the reduction of the overall footprint of the existing fleets by developing retrofit filtration devices for tailpipe, brake, and closed environments. The focus is on reducing particle/NOx for tailpipe and brake emissions. This can be filtering emissions at the source (tailpipe and brake) or filtering the air at metro stations as example of semi-closed environments to reduce the overall exposure. Currently, retrofit devices do not depend on legislation like upcoming EURO 7. Nevertheless, there is a need for public awareness, incentives, and policies to support the implementation of the filtration devices and for a market ramp-up. Moreover, the retrofit solutions should also contribute best possible to high innovation governance standards considering safety and overall sustainability along the entire life cycle of the products. The innovation project consists of pillars A) Development to bring existing retrofit technologies from TRL 4-7 to TRL 8 and B) Market preparation including sustainability assessment, public awareness, stakeholder engagement and proposal of incentive schemes.

We will present the overall project setup and scope of the Horizon Europe Innovation Action AeroSolfd. The status quo of the filtration devices will be described. The focus is on the development from TRL 4-7 to TRL 8 of the brake dust particle filter and the filtration solution for (semi-)closed environments. The ongoing developments as well as the methodology considered for the next steps will be presented. Preliminary results on how to assess the status quo of brake emission on city bus routes and about the passengers’ exposure at metro stations will be discussed in detail...
