Additional Parts You May Need for This Window Actuator

This electric chain drive requires additional components to complete your window control setup. You may need accessories such as:

• A suitable 24V DC power supply
• Power supply housing (sold separately)
• A manual vent switch like the LTA-24-AZ

Manual vent switches give building users a simple, safe way to open or close difficult to reach windows. 

The EOL N is also available in a 230V AC version, making it a practical choice for residential buildings or installations where a separate 24V DC power supply isn’t feasible.

Choosing the Right Actuator for Your Window

The EOL N is designed for natural ventilation systems. It’s ideal for improving air circulation and temperature control, but is not suitable for smoke and heat extraction systems.

If you need a solution for natural ventilation and smoke control, explore our selection of actuators, including the GEZE E 250 NT which is well suited for roof window or the Powerchain ideal for large windows.
