The filter is connected directly to the container or enclosure by a push-fit connection. The air flows through the filter medium, the dust is retained and the cleaned air exits. Depending on how it is installed, the round filter works as an exhaust air filter, for example when venting a container, or as an intake filter for clean supply air.   <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"643\" src=\"https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/round-filter-function-ratec-1-1024x643.webp\" alt=\"round filter function\" class=\"wp-image-3642\" title=\"\" srcset=\"https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/round-filter-function-ratec-1-1024x643.webp 1024w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/round-filter-function-ratec-1-767x481.webp 767w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/round-filter-function-ratec-1-300x188.webp 300w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/round-filter-function-ratec-1-1536x964.webp 1536w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/round-filter-function-ratec-1.webp 1600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 id=\"ihre-vorteile\" class=\"wp-block-heading\">Your benefits<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Compact:<\/strong> fits directly on containers, enclosures and machines.<\/li>\n\n\n\n<li><strong>Robust:<\/strong> sturdy steel housing for industrial use.<\/li>\n\n\n\n<li><strong>Tool-free:<\/strong> filter element changed quickly and easily.<\/li>\n\n\n\n<li><strong>Easy to connect:<\/strong> push-fit connection, no complex installation.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"technische-eckdaten\" class=\"wp-block-heading\">Key technical data<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Feature<\/th><th>Round filters<\/th><\/tr><\/thead><tbody><tr><td>Application<\/td><td>exhaust or intake air for smaller extraction tasks<\/td><\/tr><tr><td>Housing<\/td><td>robust steel housing<\/td><\/tr><tr><td>Filter element<\/td><td>replaceable without tools<\/td><\/tr><tr><td>Airflow, filter element<\/td><td>240 l\/(m\u00b2\u00b7s) at 200 Pa<\/td><\/tr><tr><td>Connection (standard)<\/td><td>DN 140 mm push-fit connection<\/td><\/tr><tr><td>Customisation<\/td><td>to customer requirements<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">To change the filter, the round filter is removed together with its housing and the filter element is replaced without tools.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"856\" src=\"https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/Rundfilter_KRF-1-1024x856.webp\" alt=\"Round filter exterior\" class=\"wp-image-3007\" style=\"width:397px;height:auto\" title=\"\" srcset=\"https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/Rundfilter_KRF-1-1024x856.webp 1024w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/Rundfilter_KRF-1-767x641.webp 767w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/Rundfilter_KRF-1-300x251.webp 300w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/07\/Rundfilter_KRF-1.webp 1090w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<h2 id=\"passend-fur-grossere-aufgaben\" class=\"wp-block-heading\">For larger tasks<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For more air and higher dust volumes, we offer our <a href=\"https:\/\/ratec-systems.com\/en\/cartridge-filters\/\">cartridge filters<\/a>, and for many extraction points, our <a href=\"https:\/\/ratec-systems.com\/en\/central-vacuum-systems\/\">central vacuum systems<\/a>.
