The tunnel has now been extended beyond the site of the former Vicente Calder\u00f3n stadium.<\/p>\n\n\n\n<p>The installation of the system was already completed at the end of 2022, with commissioning taking place in 2023. The separation performance of the system was confirmed by an independent laboratory and clearly exceeds the requirements of the specification.<\/p>\n\n\n\n<p>This project demonstrates the high performance and reliability of FILTRONtec filter technology in demanding tunnel operations.<\/p>\n\n\n\n<div class=\"wp-block-group has-global-padding is-content-justification-left is-layout-constrained wp-container-core-group-is-layout-fb90a72e wp-block-group-is-layout-constrained\" style=\"padding-top:var(--wp--preset--spacing--20);padding-bottom:var(--wp--preset--spacing--20)\">\n<a class=\"gb-text button-primary\" href=\"https:\/\/www.acciona.com\/updates\/news\/madrid-city-council-awards-acciona-contract-enclose-m30-ring-road-calderon\/?_adin=01836155548?\" target=\"_blank\" rel=\"noopener\">Project website<\/a>\n<\/div>\n<\/div>","protected":false},"featured_media":1120,"parent":0,"template":"","meta":{"_acf_changed":true,"inline_featured_image":false},"class_list":["post-538","projekt","type-projekt","status-publish","has-post-thumbnail","hentry"],"acf":{"ort__subheader":"Madrid, Spanien","auftraggeber":"Soterramientos Calle 30 Calderon, UTE (Acciona & Ferrovial Joint Venture)","auftragsvergabe":"03.2022","uebergabe":"07.2023","tunneleroffnung":"","luftvolumenstrom_feinstaubfilter":"Partikelfilter: 305 m\u00b3\/s"},"_links":{"self":[{"href":"http:\/\/filtrontec.de\/en\/wp-json\/wp\/v2\/projekt\/538","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/filtrontec.de\/en\/wp-json\/wp\/v2\/projekt"}],"about":[{"href":"http:\/\/filtrontec.de\/en\/wp-json\/wp\/v2\/types\/projekt"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/filtrontec.de\/en\/wp-json\/wp\/v2\/media\/1120"}],"wp:attachment":[{"href":"http:\/\/filtrontec.de\/en\/wp-json\/wp\/v2\/media?parent=538"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
