Herding Filtertechnik

From the single filter element to the completely installed filter system, the production chain starts with the filter media production and ends with the final assembly. 

The vertical range of manufacture in Germany ensures an extremely high quality standard and the greatest possible flexibility for our customers worldwide. Based on a well planned modular principle, a variety of filter system types is available, which can be individually tailored to the required application. A wide range of housing and construction materials rounds off the range of product variations.

Herding MAXX - For very high air flows

Herding FLEX – The flexible type series for all industries

Herding RESIST – For applications with high requirements on pressure resistance and easy cleanability

Herding COMP – The compact filter system for limited space

Herding PROCESS - The series for highest expectations

The newly developed Herding® BETA filter element has the unique and proven properties of the Sinter-Plate Filter and is specially designed for use at higher operating temperatures.

Well-proven properties now also up to 160 °C

The classic Herding® Sinter-Plate Filters with PE-based matrix base materials can by definition be used at operating temperatures of up to 70 °C and, as a thermostabilized variant, up to 100 °C.

The new developed and patented Herding BETA, based on a sintered matrix made of PPS, now allows the use of all known features of the classic sinter-plate filter up to a continuous operating temperature of 160 °C.

The new filter medium represents a very versatile filtration technology, which is extremely resistant to chemical attack and also hydrolysis, as well as having a range of 1 - 10 with regard to pH resistance. Absolutely constant operating conditions due to the above-described pure surface filtration are also possible with the Herding BETA for operating temperatures up to 160 °C. In addition, the new filter medium can be operated with reduced pre-cleaning pressure; significantly lower operating costs thus significantly increase energy efficiency. Like the classic sinter-plate filter, the filter medium is absolutely fiber-free and thus ideal for contamination-free material recovery.

Extensive development work by Herding's own R&D department has resulted in extensive pilot phases in various application areas with diverse types of filter systems in which the Herding BETA has been put through its paces. Examples include various dryer applications, biomass incineration plants, extraction from rotary kilns, glass tank dedusting and high-temperature filtration behind mill systems.

The Herding® filter technology bases on pure surface filtration. It sustainably protects man and machine from harmful production emissions and enables absolutely sort- and contamination-free material recovery. This increases directly your productivity.

Lowest clean gas values, absolutely constant operating conditions, highest availability and energy efficiency are key features of the innovative technology. Herding® filter elements show extreme durability and, depending on the process, long service life times of more than 15 years. Thereby the filters make a valueable contribution to environmental protection and sustainability.

Herding® filter elements have proven themselves for decades in effective and safe particle separation in almost all areas of industry . Even with finest grain sizes, energy-efficient air recirculation is possible in most cases, proven even with toxic dust. Numerous applications can be covered in a temperature range of up to 450 °C.
