In short: Three ventilation kits compared: VS-KA chain actuator from €87.99, VS-ZA 800 rack-and-pinion actuator from €136.99 and VS-LA linear actuator from €184 net – each with matching controls.
A ventilation kit contains the window actuator and the matching controls. For 24 V this is the VS-C24-7A control with radio remote and optional sensor, for 230 V a ventilation switch.
The three kits
- VS-KA ventilation kit: chain actuator for tilt, top-hung and roof windows, from €87.99 net
- VS-ZA 800 ventilation kit: rack-and-pinion actuator for heavy sashes and continuous rooflights, from €136.99 net
- VS-LA ventilation kit: linear actuator (600–5000 N) for roof windows and skylight domes, from €184 net
Which kit fits?
For normal tilt and roof windows the VS-KA kit is usually enough. For heavy sashes and long window bands the VS-ZA 800 kit is suitable, for skylight domes and long strokes the VS-LA kit. Up to 7 actuators can be connected to one control unit.
