Wire Mesh Process Filters with Precise Selectivity - Individually Developed According to Your Requirements

Filtration of Impurities, Homogenization, Prevention of Agglomerates

Taking account of the customer's extensive catalogue of requirements and quality management, Haver & Boecker tests and implements process filters in all shapes and sizes, pleated or flat, with frame or plastic injection moulding.

Advantages of homogenization or filtration with wire mesh

Wire mesh products are used in chemistry, medical engineering, plastics processing and water treatment, for example, and are used, depending on the application, to break up and retain agglomerates, to homogenise a medium for a uniform viscosity and to filter out impurities. Metal wire meshes have exact geometrical structures, providing filtering performance that is consistent over the entire filter surface, can be flexibly processed and are easy to clean. By selecting the weave and the materials of the wires and the filter components, the mechanical, chemical and physical properties, such as corrosion and heat resistance can be adapted to the particular application. In addition to standard plastics such as PA66, Haver & Boecker also processes special materials such as the heat-resistant PEEK and LCP for plastic injection moulding.

Process filter for water treatment with the RPD HIFLO-S

A filter is comprised of at least one filter layer depending on the desired separation efficiency and the ambient conditions. 2D and 3D wire meshes with square or rectangular apertures or filter weaves from the own production are used. The high-performance MINIMESH® RPD HIFLO-S filter weave offers the ideal prerequisite for water treatment. Compared with conventional filter weaves, the three-dimensional cloth structure has a significantly higher number of pores and thus a larger surface area within the same amount of space. The flow rate can be more than doubled and the flow characteristics optimized with the same pore size. The efficiency of filtration is no longer directly dependent on the wire diameter, so that even a filter cloth made of comparatively strong corrosion-resistant wire can have a pore size of 5 microns. If required, the cloth structure can be simulated in advance, the filtration properties can be precisely calculated and the filter cloth can thus be optimally designed without the need for elaborate testing. In addition, the underlying structure of the high-performance filter weave promotes excellent dirt collection and cleaning performance. Even when used in process filters, the RPD HIFLO-S offers impressively precise selectivity and long dimensional stability.

Extensive testing and documentation accompany the production process

In order to implement customer ideas and requirements directly in the production of filters and fabricated parts, Haver & Boecker develops the necessary tools and equipment for processing the cloth up to and including integrated in-house production lines. Parts of the process chain can be carried out under clean room conditions. A 100% camera test is used to visually monitor mass production products. In this way, the final filter is completely documented.
