Dosing and distributing granulates has been the core competence of RAUCH Landmaschinen since 1921. Now in its fifth generation, the family-owned company manufactures innovative products for fertilizer, municipal and seeding technology. Reliability, optimized work processes and qualified employees are the basis for the success of a solid business policy.
All over the world, farmers, local authorities, large companies and contractors rely on the quality, reliability and long service life of RAUCH products. RAUCH spreaders are not only top in terms of processing quality and spreading precision, they also meet the highest standards of environmentally friendly production and assembly. This is supported, among other things, by the consistent use of an emission-free powder coating system.

RAUCH agricultural machinery - precision meets innovation
For over 100 years, RAUCH Landmaschinenfabrik GmbH from Rheinmünster has stood for high-precision spreading and metering technology in agriculture and municipal services. As a multi-award-winning family business, RAUCH sets standards in quality, sustainability and innovation - from smart fertilizer technology to modern powder coating. With over 400 employees, an export share of 73% and more than 170 patents, RAUCH is a leading driving force for sustainable agricultural technology “Made in Germany”.

Challenge
No waste water is produced during washing and degreasing thanks to the in-house vacuum water treatment system. Treated water is temporarily stored in tanks and fed into the process as required. There are also no environmentally harmful paint residues in the powder chamber. Powder dust that does not adhere to the workpiece is extracted, cleaned and fed back into the coating process. In this way, high-quality RAUCH surface finishing also helps to protect people and the environment.
In powder coating, electrically conductive materials are coated with powder paint. The coating system consists of a surface pre-treatment, an electronic coating zone and an intermediate and main dryer. The parts to be coated are transported by a conveyor system during the treatment process. Typical substrates for powder coating are steel, galvanized steel and aluminium. The powder coating particles are first fluidized. During this process, the powder must be cleaned of fibers, coarse particles and dirt.

Solution statement
- The filter components and systems from Filtration Group Industrial make an effective contribution to conserving resources, reducing wear and optimizing machine utilization in surface technology at RAUCH Landmaschinenfabrik GmbH.
- The type 852 908 Ti 08-10 NOK cylindrical dust filter elements from Filtration Group ensure reliable cleaning of dusty air during powder coating.
- A few years ago, a rectangular FG dedusting system was purchased for the extraction system from a leading global supplier of equipment and systems for electrostatic powder coating.
- Thanks to the FILCOM logistics concept, it was possible to provide the customer with a fast and efficient supply of spare parts in the area of filtration technology.

Customer benefit
- By using a special pleat spacing technique with polyester-based filter media, the dust filter elements achieve improved settling behavior. The favorable flow conditions result in up to 44 % higher performance and utilization of the entire filter surface of the filter cartridge.
- The cleaning process is facilitated by the embossed spacers in the filter material in the form of a cam. There is no blockage of the pleats, the air passage is constantly guaranteed to the highest degree and the filtered medium can be perfectly cleaned back out of the pleat to ensure an extremely low differential pressure.
- The filter material achieves a good separation efficiency in the fine dust range and represents a cost-optimized solution for applications in which electrical charges of the dust filter cake have to be discharged.
