Qualified staff, computer-aided analysis and measuring methods, the availability of all required test stands according to the ISO - test standards as well as the continuous production control of the filter elements enable INTERNORMEN Technology to be one of the world-leading manufacturers of filter elements at present.
We produce more than 3500 different types of filter elements which are constructed and produced at our headquarter. Our elements are distinguished by a very high dirt hold capacity and a high pressure resistance which guarantee a long life time. The beta ratio of the filter element and its permanent efficiency are guaranteed for high pressure differences. Filter materials, bonding and processing are regularly controlled by means of bubble-point tests on our test stand according to ISO 2942. INTERNORMEN Technology elements can be supplied with 100 % bubble-point tests and corresponding certificates on request. The glass fibre material „VG“ used in filter elements for fine fitration is supported by a support fleece and a stainless steel wire mesh and thereby protected against damage during production and later during filtration at high pressure differences. The bonding of the filter material to the end caps and the seam is executed with maximum accuracy. By using of special high quality adhesies, a homogeneous connection of the parts is achieved. In addition to tests developed by INTERNORMEN Technology testing of our filter elements to the following ISO-Standards is done: ISO 2941 Verification of collapse/burst resistance ISO 2942 Verification of fabrication integrity ISO 2943 Verification of material compatibility with fluids ISO 3723 Method for end load testing ISO 3724 Verification of flow fatigue characteristics ISO 3968 Evaluation of pressure drop versus flow characteristics ISO 16889 Multi-Pass method for evaluating filtration performance To be able to meet our customers‘requirements optimally, we have a very large warehouse stock availability. This enables us to guarantee a short-term delivery and our customers avoiding the hold on own stock. Apart from the original – filter elements fitting our own filter housings we also offer exchange elements, which are for use with the filter housings of the following filter manufacturers: Pall, Mahle, Bosch Rexroth (former Eppensteiner), Hydac, Parker To facilitate you the survey of our wide range of products, you can download a checklist of the elements that are mostly enquired. You cannot find the element you request? Don’t hesitate to ask about it – we are pleased to help you!
