Filter cartridges and spare parts

High-performance filter cartridges

As a manufacturing company dealing with the production of extraction equipment, we have our own production of filters for our AFJ series extraction equipment. Thanks to our many years of experience in the market, we have also started to service extraction systems that use different filters. We have established cooperation with Czech and foreign manufacturers of filtration elements and thanks to this we are able to offer service of extraction equipment in the highest quality including delivery of original filtration elements.

We have our own filters for our WELDUST equipment and also supply these filters as spare parts for extraction.

We will be happy to advise you on selecting the right filter for your equipment and your process.



The filter cartridges we equip our equipment with are extremely powerful and have an extremely long service life. The structure and composition of these filters is based on the composition of several layers into one filter. The filters are made of solid material and are suitable for extreme processes.

Highly efficient pre-filter

We use metallic filters in our extraction ranges to achieve a longer lifetime for our main filters. The metallic filter is designed to catch coarser particles or large and sharp things that could otherwise damage the filter. These filters have a high efficiency. Their main advantage is that they are washable.
