It is mounted on the frame or the sash and is suitable for bottom-hung, top-hung and roof windows \u2013 for daily ventilation as well as for smoke and heat exhaust ventilation (SHEV). Typical values are 24 V or 230 V, forces of 250 to 1500 N and strokes of up to 1000 mm. You will find suitable models under <a href=\"\/en\/product-category\/chain-drives\/\">Chain actuators<\/a>.<\/p>\n<p><strong>In brief:<\/strong> Chain actuators suit most bottom-hung and top-hung windows and are particularly compact. Linear or spindle actuators are suited to heavy rooflights and roof windows, rack-and-pinion actuators to very large and heavy sashes. The deciding factors are force, stroke, space on the frame and voltage (24 V or 230 V).<\/p>\n<p><!-- wp:paragraph --><\/p>\n<p id=\"p-rc_b31c610de7f857f1-16\">Choosing the right <a href=\"https:\/\/ventsystems.de\/en\/shop-with-filter\/\">Window drive<\/a> is crucial for the functionality of a building, be it for daily use <strong>natural ventilation<\/strong> or for safety in case of fire by <strong>Smoke and heat exhaust systems (SHEVS)<\/strong>.

Linear actuators (spindle actuators) offer high push and pull forces and are more robust against wind loads on the roof than simple chain actuators.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are rack-and-pinion actuators used for?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For large rooflights, heavy louvre windows and projects with extreme mechanical requirements. The force is transmitted via a gear wheel onto a solid rack \u2013 this makes rack-and-pinion actuators particularly resistant and durable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">24 V or 230 V \u2013 which operating voltage is the right one?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">24 V DC is mostly used for smoke and heat exhaust (SHEV) systems with emergency power batteries. 230 V AC is suitable for everyday comfort ventilation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Suitable products at Vent Systems<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"\/en\/product-category\/chain-drives\/\">All chain drives in the shop<\/a><\/li>\n\n\n<li><a href=\"\/en\/product-category\/spindle-drives\/\">All linear actuators in the shop<\/a><\/li>\n\n\n<li><a href=\"\/en\/product-category\/rack-and-pinion-drives\/\">All rack and pinion drives in the shop<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Read more:<\/strong> <a href=\"https:\/\/ventsystems.de\/en\/chain-drive-for-facade-windows-typical-applications-at-a-glance\/\">01 Chain drive for facade windows \u2013 typical applications at a glance<\/a> \u00b7 <a href=\"https:\/\/ventsystems.de\/en\/rack-and-pinion-drives-in-building-automation\/\">Rack-and-pinion drives in building automation<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Read more about spindle actuators in the guide <a href=\"\/en\/spindle-actuator-for-windows\/\">Spindle actuator for windows and skylights<\/a>.
