Haver & Boecker is a global leader in the design and manufacture of high-performance wire mesh filtration solutions. Whether it’s aerospace and aviation, automotive, electrical engineering, medicine, chemicals, water filtration, machine building or plastics processing – customised solutions from Haver & Boecker offer the basis for efficient production processes, reliable function, optimum quality & distinctive design.

Constant investment in new technology and R&D has resulted in the development of new weave types as well as innovative automation solutions. In addition to filters and shaped parts made of metal wire mesh these latest high-tech products will be showcased in October at the International Filtech Trade Fair in Cologne, Germany.

Compared to other filter media, the specific properties of a woven wire mesh may be precisely described geometrically and defined through the type of weave, wire diameter and mesh count. For the user and manufacturer of woven wire filters, this is a considerable advantage, because geometric pore size and permeability can be precisely calculated beforehand. With these “precision pores” it is possible to attain a higher separation effect and shape stability.

Where conventional filter cloths have reached their limits, the new developed MINIMESH® RPD HIFLO-S opens up new dimensions for filtration. Using new weaving technology developed by Haver & Boecker, a three-dimensional pore geometry is created that makes industrial filtration processes more efficient, quicker and more economical than ever previously possible.

The open surface over an area is significantly increased due to the weaving structure. The medium‘s flow-through rate can be doubled when compared to conventional filter cloth having the same

pore size, for example the MINIMESH® DTW-S. In addition, the flow conditions are optimized and turbulence around the filter cloth is effectively avoided.

The pore size within a batch can be calibrated as desired from 5 µm to 40 µm.

The new filter cloth can be manufactured from standard diameter wires. This has a positive effect on cost. Moreover it is now possible to weave special materials such as Avesta, Hastelloy, Inconel or Titanium in the small pore size range, which previously had not been possible. Thus for the first time RPD HIFLO-S offers a corrosion and temperature resistant filter cloth with pore sizes below 40 µm.

The depth structure of RPD HIFLO-S offers a high separation effect without rapid blinding. Dirt holding capacity and cleaning capability have proven to be excellent.

Characteristics:

• For a given pores size, twice the flow of comparable filter cloths • Excellent cut-point and stability • Corrosion and temperature resistant special alloys • Optimum dirt holding and purging properties • Different pore sizes in one batch from 5 µm to 40 µm About Haver & Boecker

Haver & Boecker is an independent, family owned company with its headquarters in Oelde, Westphalia, Germany. Founded in 1887 it operates today two diverse and distinct product divisions: The Wire Weaving and Machinery Division. Together with more than 50 subsidiaries and 150 representatives on all five continents, Haver & Boecker operates worldwide with about 2,950 employees. Its work is based upon experience, continuous research and development of its products and manufacturing processes, along with the knowledge and ability of its staff.

The Wire Weaving Division manufactures woven wire cloth and processes it into engineered woven wire products. These are used for the screening and filtration in the chemical, plastics and automobile industries, in aviation and aerospace, electronics, industrial and analysis screening, in the food industry as well as for architectural applications.

The Machinery Division and its technology brands is specialized in industrial processing, transport, storage, mixing, filling, packing, palletizing and loading of bulk materials. The product range includes the development, production and distribution of machines for agglomeration, pelletizing and washing for building materials and mineral goods, plant engineering and services.

Flow conditions are optimised and turbulence around the filter cloth is effectively avoided. Geometric pore size and permeability of a woven wire mesh can be precisely calculated beforehand. The corresponding mINImeSH® specification is validated using established evaluation methods. The glass bead test has become an established and authoritative cross-industry test method.
