It is suitable for large bottom-hung, top-hung and side-hung sashes as well as heavy roof windows and rooflights.<\/p>\n<h3>VS-LA-i smart linear drive overview<\/h3>\n<p>VS-LA-i smart linear actuator: quiet, programmable, and with a long service life. The actuator features a synchronization function and can be integrated into bus systems. This makes the VS-LA-i ideal for demanding applications in ventilation, smoke and heat exhaust ventilation (SHEV), and facade systems, such as for large tilt, turn, and pivot windows, as well as heavy-duty components. <a href=\"https:\/\/ventsystems.de\/en\/automated-roof-ventilation-in-building-construction\/\">Roof windows and skylights<\/a>. 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<h3>Selection, assembly and further information<\/h3>\n<p>Which drive mechanism is suitable for your window depends primarily on the sash weight, opening width, and installation situation.
