Kwerk GmbH - Your Trusted Source for Superior Filter Solutions and Swift Delivery















 

Filter cartridges and filter housings from the B2B portal Kwerk GmbH offer customers great flexibility in choosing their filtration solution and its application. In the field of filter technology, we provide a wide range of high-quality products, including PENTEK cartridge filters, bag filters, and related accessories. Each variant has its specific advantages and disadvantages, but ultimately, the filtration result is what matters. Based on that, the appropriate filter elements can be selected. Our filter cartridges are high-quality filter inserts designed for use in process engineering for water treatment, as well as in the chemical and process industries. Regardless of the medium, whether in electroplating, water treatment, or the production of special process baths, the B2B portal Kwerk GmbH always has the right solution in its delivery program.

Standard products in our range include:


- Wound filter cartridges
- Activated carbon filter cartridges
- BIG BLUE housings
- ECP filter cartridges
- PCF filter cartridges

We offer you a wide selection of depth filtration, surface filtration, and activated carbon filtration. We attach great importance to customer-oriented consultation. The filter cartridges and filter housings from Kwerk GmbH are delivered directly from stock within 1 day.

Filter Cartridges:


Filtration with filter cartridges offers various application possibilities in water treatment. Depending on the filter cartridge and medium, the filter elements are also used in the treatment of solvents, paints, gases, electroplating baths, varnishes, oils, and chemicals. One particular application area is the removal of odors and flavors. Activated carbon filter cartridges, in particular, are used for these applications.

Depth Filtration:


In depth filtration, turbidity and sediments present in the water penetrate various depths of the filter cartridge and are retained there. Our wound filter cartridges are characterized by long service life, various micron ratings and sizes, an affordable price, and high temperature resistance.

Surface Filtration:


For maximum dirt holding capacity, filter cartridges from the field of surface filtration are used. This process retains impurities on the surface of the filter medium. With a variety of sizes and micron options, you benefit from durable materials and extremely low fiber release, making the filter cartridges suitable for a wide range of applications.

Activated Carbon Filtration:


The B2B portal Kwerk GmbH offers you a wide selection of high-quality activated carbon filters for the water and wastewater technology sector. Our comprehensive range of activated carbon filtration solutions is based on various core technologies, including conventional activated carbon blocks. Choose the conventional activated carbon block for applications where the reduction of chloramines or organic substances (VOC and TTHM) is required. Or opt for Fibredyne technology when it comes to reducing particulates, clog resistance, reducing large organic compounds, and maintaining a low pressure drop over the lifespan of the filter cartridge. Our offering also includes granular and pleated activated carbon filters designed to reduce bacteria, cysts, as well as chlorine and flavors.

Trust in the B2B portal Kwerk GmbH and benefit from our many years of experience and extensive range of filter solutions. Contact us today to discuss your individual requirements.
