Filtration at BOLL & KIRCH

Boll & Kirch Filterbau GmbH deals exclusively with development and the production of filter systems for liquids and gases.

The principle of filtration is simple and omnipresent in our daily life: a liquid or a gas passes through a filter element whose mesh, openings or pores are dimensioned to prevent specific, unwanted particles from getting through.

At industrial level, this requires a command of complex processes which are influenced by various material qualities and environmental conditions. These include quantity, pressure, temperature, density, viscosity, corrosiveness, the level of contamination, particle size and the type of medium being filtered. Years of systematic research into these influential factors and their interaction enable us to offer a series of filter systems for various applications and fields which are guaranteed to maximise performance, reliability and protection.

Boll & Kirch Filterbau GmbH products can be used for many applications. They include very different branches of industry, such as ship- and engine-building, steel as well as the automotive and chemical industries, power generation, water treatment and supply. The media requiring filtration also differ greatly, e.g. fuels, lubricant, gas, coolants, oils, cleaning agents and water. Accordingly, the demands on the single applications vary strongly. With concentrated and fully differentiated competence we know our profession in depth and breadth.
