Core business and product range

Krone Filter Solutions offers a comprehensive range of filters designed to be high-quality, efficient and low-maintenance. Their main product lines include:

• Automatic self-cleaning filters
• KAF Bernoulli® filters: This is one of Krone Filter Solutions’ best-known products and a registered trademark. Filters based on the Bernoulli principle are very well suited for high flow rates and low pressure losses. They are highly efficient in filtering seawater and cooling liquids. They can handle particle sizes from 25 microns up to 50 mm.
• KRF backwash filters: These are used for efficient liquid filtration and clean themselves through backwashing.
• KAS liquid filters: A self-washing, automatic and nearly maintenance-free filter designed to remove solid particles from heavily contaminated water and other process liquids. It can separate particles from 50 micrometers up to 5 millimeters.
• Basket filters
• Simplex basket filters, KSF series: Versatile strainer basket filters for liquid substances, designed to provide a large filter surface area and long service life. They are manufactured from several materials, such as ductile iron, GGG-50, bronze, steel and stainless steel. Inline filters, KWF, are also available.
• Duplex filters / change-over filters, KDF series: These filters consist of two filters of the same size, allowing filter replacement or cleaning without interrupting the process. They are available with different switching mechanisms, such as ball valve or butterfly valve switching. The KDF series is often used for filtering water, oil and hydraulic fluids.

Other filters and solutions

• Customized filters: Filters manufactured according to customer needs, such as models with special closures or heating jackets.
