WINDMASTER 500mm Roof Turbine Ventilator
The WINDMASTER 500 mm roof ventilator is a roof-mounted turbine-style extractor that uses wind movement and rising internal air to assist ventilation. The original McDURCH listing describes a stainless-steel construction and bearing-supported rotating unit.
Product details
- Listed throat or model size: 500 mm; confirm how the manufacturer defines the dimension.
- Original description identifies stainless-steel components and a double-bearing arrangement.
- Roof-mounted turbine design is intended for passive airflow rather than a motor-driven fan.
- The catalogue mentions optional finish colours and roof-pitch adaptation.
Applications
Potential installation sites include workshops, warehouses and production sheds where passive roof extraction is appropriate as part of an overall ventilation plan.
Before ordering
Confirm roof flashing type, throat diameter, pitch compatibility, weather sealing, wind exposure, airflow performance, installation method and warranty documentation. Passive ventilators should not be presented as a substitute for required mechanical extraction.
