Smoke Ventilation
We supply reliable, EN12101-2 tested WindowMaster smoke ventilation actuators such as the WMU 842 and WMU 836, designed to ensure safety, performance, and compliance. Our EN12101-10 control panels include the WSC-104 for single-zone stairwells, and multi-zone FlexiSmoke panels like the WSC-520, WSC-540, and WSC-560 for larger smoke ventilation systems. We also stock the WindowMaster WSK 501, a widely used break glass unit for smoke ventilation systems.
Natural Ventilation
Our natural ventilation solutions include compact, efficient actuators like the WMX 804 and control panels such as the WCC-103, WCC-106, WCC-310, and WCC-320. These systems are designed to improve airflow and energy efficiency across a variety of building layouts.
The WindowMaster range is also often integrated into BMS (Building Management Systems) for more advanced ventilation control requirements.
