Nonwoven Equipment for Filter Media Manufacturers

Filter media is unforgiving. A web that looks fine on the roll can still fail a DOP test or blow past a pressure-drop spec once it is pleated and put under load. That is why the machinery matters as much as the fibre choice, and it is where we spend most of our time with filtration customers, matching a filtration nonwoven line to the grade of media a plant actually needs to sell.

Most filter producers we work with are not buying a single machine. They need a coherent run from opening and blending through carding, web forming, bonding and cutting, all tuned so basis weight stays inside tolerance across the full width. We supply that lineup as one package. KSG Group has been building nonwoven machinery for more than 30 years and has installed lines in over 40 countries, so we tend to know where a given media grade will give a customer trouble before the first bale is opened.

For dry-laid filter media the backbone is usually a carding machine feeding a cross lapper, then either thermal bonding or a needle punching machine depending on whether the customer wants a lofty depth filter or a firmer supported media. We also build the dryers, the padding units for resin-treated grades, and the dust extraction and filter housings that keep the carding room clean. Because we make those pieces ourselves, the interfaces between them are already sorted out, which is where a lot of mixed-supplier projects lose weeks during commissioning.

Line speed and changeover are the two questions filtration buyers ask first. Depth media for coarse air filters runs fast at higher web weights; fine media for HEPA-class pleating runs slower and demands very steady weight control. We size the drives, condensers and lapper stroke around the customer's actual product mix rather than a single headline speed, and we set the line up so a weight or width change is a recipe recall, not a half-shift of manual trial and error.

If you are planning a new filter media plant or debottlenecking an existing one, we can quote the whole line, from layout drawings through installation and commissioning, or fill in the specific machines you are missing. Send us your target media grades, widths and output and we will come back with a workable equipment lineup and a realistic schedule. KSG Group builds it in Korea and installs it on your floor.
