Bag filters are mainly used for indoor air treatment. Pocket filters are therefore crucial for minimizing health risks and for creating the best possible working and production conditions. A distinction is made between coarse and fine filtration. The former are used as pre-filters for fine dust filters or in air conditioning systems in offices. Pocket filters for fine dust can be found in all ventilation systems, for example in the medical, pharmaceutical or food production sectors.

The production range of filter inserts includes numerous diameters of 100m and 660mm and lengths of up to 2,000mm. The filter surfaces are much larger compared to traditional bag filters. Easy installation, careful construction, low consumption of compressed air during cleaning and a competitive price complete the essential characteristics of these cartridge filter elements.

Irradiating the water with ultraviolet light, the oldest and most natural disinfection method, offers optimal protection against the risk of infection. UV light reliably inactivates pathogens and works without the formation of harmful by-products. Crucial to water disinfection with UV light is the avoidance of chlorine as a disinfectant and the chlorine compounds formed during chlorination. Our systems are characterized by an extraordinarily high disinfection performance with a compact design and low energy consumption. Our UV systems are designed in accordance with applicable laws, standards and guidelines.
