It combines a compact design with reliable performance and is perfectly suited for casement and tilt windows as well as roof windows.<\/p>\n<p>The drives can be integrated into 24 V systems and impress with their quiet, low-maintenance, and durable operation. The entire VS-KA series offers flexible solutions for virtually any requirement: Push and pull forces from 250 N to 1,500 N and variable chain lengths from 100 mm to 1,000 mm (infinitely adjustable depending on the model) can be freely selected via the selection bar. As a versatile <a href=\"https:\/\/ventsystems.de\/en\/chain-drive-linear-drive-or-rack-and-pinion-drive-which-window-drive-is-suitable-for-which-application\/\">Window drive<\/a> , the VS-KA series is suitable for a wide range of window, roof window and skylight applications in ventilation and fa\u00e7ade systems. For use in smoke ventilation systems, the actuator, the window and an approved smoke control panel must be matched to one another and verified for each project \u2013 we will be happy to advise you.<\/p>\n<p><strong>Replacement for chain drives from other manufacturers:<\/strong> The VS-KA is a suitable alternative to many chain drives from GEZE (e.g. ECchain, Slimchain, Powerchain), Aum\u00fcller (KS2, KS4, KS15), Kingspan STG (LM, CDs, KCD), D+H (KA 34, KA 54), WindowMaster (WMX, WMU) and HAUTAU (SKA, EKA).

You select force and stroke directly in the variant selection.<\/p>\n<h4>Which windows is the VS-KA chain actuator suitable for?<\/h4>\n<p>For top-hung and bottom-hung sashes, roof windows and rooflights in ventilation and fa\u00e7ade applications \u2013 wherever a compact, quiet and low-maintenance actuator is required.<\/p>\n<h4>Is the VS-KA available in 24 V and 230 V?<\/h4>\n<p>Yes, the VS-KA is available in 24 V and 230 V. For 24 V actuators you need a suitable control unit, for example the VS-C24-7A.<\/p>\n<h4>Can the VS-KA be used in smoke and heat exhaust (SHEV) systems?<\/h4>\n<p>For use in smoke ventilation systems, the actuator, the window and an approved smoke control panel must be matched to one another and verified for each project \u2013 we will be happy to advise you.<\/p>\n<h4>Related guides<\/h4>\n<ul>\n<li><a href=\"\/en\/connecting-chain-actuator\/\">Connecting a chain actuator<\/a><\/li>\n<li><a href=\"\/en\/electric-fanlight-opener\/\">Electric fanlight opener<\/a><\/li>\n<li><a href=\"\/en\/retrofitting-electric-window-openers\/\">Retrofitting electric window openers<\/a><\/li>\n<li><a href=\"\/en\/calculate-chain-length-for-window-drive\/\">Calculating chain length and stroke<\/a><\/li>\n<li><a href=\"\/en\/window-actuator-24v-or-230v\/\">Window actuator: 24 V or 230 V?<\/a><\/li>\n<li><a href=\"\/en\/chain-actuator-roof-windows\/\">Chain actuator for roof windows<\/a><\/li>\n<li><a href=\"\/en\/ventilation-control-window-drives\/\">Ventilation control for window actuators<\/a><\/li>\n<li><a href=\"\/en\/how-to-properly-install-an-electric-window-drive-5-points-for-a-reliable-installation\/\">Installing a window actuator correctly<\/a><\/li>\n<\/ul>\n<p class=\"vs-lexikon-links\"><strong>Technical terms explained:<\/strong> <a href=\"\/en\/dictionary\/thrust\/\">Thrust<\/a> \u00b7 <a href=\"\/en\/dictionary\/stroke-length\/\">Stroke length<\/a> \u00b7 <a href=\"\/en\/dictionary\/ip-rating\/\">Protection class (IP)<\/a> \u00b7 <a href=\"\/en\/dictionary\/tandem-operation\/\">Tandem\/synchronous operation<\/a> \u00b7 <a href=\"\/en\/dictionary\/safety-stay\/\">safety stay<\/a> \u2013 more in the <a href=\"\/en\/dictionary\/\">Window actuator glossary<\/a>.<\/p>\n<p><strong>Detailed comparisons:<\/strong> <a href=\"\/en\/geze-slimchain-alternative\/\">GEZE Slimchain<\/a> \u00b7 <a href=\"\/en\/geze-ecchain-alternative\/\">GEZE ECchain<\/a> \u00b7 <a href=\"\/en\/aumueller-ks2-ks4-alternative\/\">Aum\u00fcller KS2 \/ KS4<\/a> \u00b7 <a href=\"\/en\/windowmaster-wml-825-alternative\/\">WindowMaster WML 825 (VELUX)<\/a> \u00b7 <a href=\"\/en\/geze-e-212-alternative\/\">GEZE E 212 (fanlight)<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>VS-KA chain drive \u2013 universal, with 250 N to 1500 N thrust.<\/p>\n<p>Price includes standard bracket set.<\/p>","protected":false},"featured_media":10468,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[101],"product_cat":[1134],"product_tag":[],"class_list":["post-14316","product","type-product","status-publish","has-post-thumbnail","product_brand-vent-systems","product_cat-kettenantriebe","pa_hublaenge-51","pa_hublaenge-64","pa_hublaenge-52","pa_hublaenge-53","pa_hublaenge-54","pa_hublaenge-55","pa_hublaenge-56","pa_hublaenge-57","pa_hublaenge-58","pa_hublaenge-59","pa_hublaenge-62","pa_hublaenge-68","pa_hublaenge-63","pa_hublaenge-69","pa_schubkraft-122","pa_schubkraft-1194","pa_schubkraft-129","pa_schubkraft-123","pa_spannung-230-v","pa_spannung-24-v","first","instock","taxable","shipping-taxable","purchasable","product-type-variable","has-product-safety-information"],"acf":[],"_links":{"self":[{"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/product\/14316","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/comments?post=14316"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/media\/10468"}],"wp:attachment":[{"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/media?parent=14316"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/product_brand?post=14316"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/product_cat?post=14316"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ventsystems.de\/en\/wp-json\/wp\/v2\/product_tag?post=14316"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
