Filters play a decisive role for the functionality and working life of engines in all kinds of vehicles. All working fluids like fuels, oil, and air for cooling must be free of particles and water. Modern injection systems for diesel fuel operate at extremely high pressures. Particles will destroy the injection pumps within a short time. Modern engines are equipped with exhaust gas recirculation systems to reduce emissions and fuel consumption. Here particle filters are necessary for maintaining the lifetime of valves. New drives that work on the basis of natural gas, liquified natural gas (LNG), or hydrogen also demand particle-free fuels. This is ensured by our fuelling filters and coalesc

Filtration is used in the chemical industry for processing reagents, e.g. to separate impurities or undissolved substances from solutions, and for processing reaction mixtures. Pre-filtered reagents produce higher quality of reaction products.  Our filters enable the recovery of solid products or by-products from reaction mixtures, the separation of biomass from product solutions after fermentation, or the recovery of solid catalysts or other auxiliaries like powdery or granular adsorbents or absorbents.  In addition, filtration of process flows protects downstream plant components from depositions or erosion, and facilitates thermal separation processes like distillation.

In the food and beverage industry, high hygienic standards must be met in combination with efficiency and increasing consumer demands on product quality and product variety. Stainless steel filter elements are advantageous in this context due to their hygienic design without dead zones. They can be cleaned in place and are therefore highly suitable for use in plants that process different types of products. As a result, our filters offer the most economical alternative in comparison to filters that cannot be cleaned and therefore cause additional costs for replacement and waste disposal. Seebach filters are used for virtually all imaginable liquid foods, even for high-viscosity liquids like

Almost every production stage in the semiconductor industry is characterized by the demand for the highest possible cleanliness and particle freedom of the working environment and all the media used in it. As semiconductor products become steadily smaller and more efficient, the fabrication of wafer surfaces is carried out in dimensions of 1 µm and below. Any disturbing particle can make a chip useless. Therefore most of production processes are carried out in cleanrooms, using ultrapure water.  Here, our filter elements are used for de-dusting in supply air and exhaust air ducts, mostly as pre-filters prior to HEPA filtration. Our products are also used as pre-filters In the production of

Many chemical reactions take place in the presence of a solid catalyst. Powdery catalysts based on noble metals (e.g. platinum) or zinc complexes are frequently used. These catalysts are often highly specialized and therefore very expensive.  Cross-flow filtration allows for continuous catalyst recovery from reaction mixtures and subsequent return into the process. This means long-term cost savings. Again filter elements made form stainless steel or special alloys are best suited to the task due to their extensive chemical resistance. Typical examples of the application of our filters for catalyst recovery are the production of polyurethane via the intermediates toluene diamine (TDA) and to

Applications in the aerospace sector pose highest demands on the thermal, chemical, and mechanical resistance of filter systems. Depending on the application site, extremely high temperatures as well as temperatures well below freezing are possible. Operating media and fuels for such applications must meet high standards with regard to the concentrations of particles and free water. The chemical composition of fuels and lubricants is adapted to harsh environmental conditions and thus challenges the chemical resistance of filter materials. Aggressive media, together with extreme temperatures, make the use of high alloy steels, titanium, and special materials necessary. The requirement to mini

A large proportion of pharmaceutically active compounds is available in a solid state in the form of pills or tablets. Other drugs are sold as granulate or tablets to be dissolved in water before consuming. The journey from a pharmaceutically active compound in solution to a ready-to-serve solid product passes through several process stages, such as spray or fluidized bed drying, grinding, and mechanical separation stages, like sieving, sifting, or classifying. Transport between different process steps is carried out pneumatically. Transport gases (air or nitrogen) that are in contact with products or auxiliaries must be free of solid impurities. Fluidized bed systems or wind sifters demand

Process water recycling and the reuse of cleaned waste water are basic elements in state-of-the-art sustainable production processes, as is the recovery of valuable substances from process waste water. Seebach filters can be used anywhere, where particles and oil must be separated from water flows.In this context, the treatment of cooling water, washing water from industrial cleaning processes, and boiling water are especially worth noting. Filtered water can be transferred to further treatment processes or re-used as service or extinguishing water. A special application is the recovery of demineralized water from quenching water, which emerges from gasification processes at high temperatur

Particle filters are used to clean water from the public drinking water network at the inflow into buildings and for the fine filtration of drinking water near to the point of use. They remove suspended sand grains and particles, such as rust, flax fibres, or debris from broken seals, from the pipe system. They also reduce the loading on   local waste water treatment plants through the pre-separation of suspended solids.

Filters for military applications must be extremely robust and durable. They must also be easy to maintain, without using complex tools or auxiliaries. Here, our stainless steel and other metal filters have several advantages over plastic filters. Our filters for military applications are designed to withstand different climatic conditions in all possible locations. They are installed in vehicles for fuel and oil filtration, in mobile power generators for the treatment of liquid or gaseous fuels, and for exhaust gas filtration. Special applications include the filtration of operation media in fuel cells (e.g. hydrogen filtration) or the filtration of liquids in submarines. Here, spatial cond
