Compact 24 VDC window drive for operating VELUX roof windows GGL and GGU from size F06 and VL from size 035. This drive does not fit the new generation windows with "K" in the type designation (e.g.MK06).
The window drive is mounted behind the ventilation flap and is therefore not visible when the window is closed.
The housing and the chains of the chain drive are protected against corrosion.
The WML 825 is approved according to VdS 2580. Approval no.: G502003.
Cable extensions must be ordered separately.
Area of application

- with VdS approval no.: G502003
Note:
If a chain drive WMG 500, KEM 110, KEM 113, KEM 115, EBM or EB was previously installed in the window, the strike plate as well as the catches and friction springs must be reinstalled. The ventilation flap may also need to be replaced to ensure proper operation of the WML.
The use of shutters on a window with a SHEV system must be coordinated with the responsible fire protection expert or the planning office. It must be ensured that when the SHEV system is triggered, the roller shutter is raised first and then the window opens.
