Bradford Maestro BAL™ Roof Ventilator
Bradford Maestro BAL is a powered roof ventilator designed for homes in bushfire-prone areas. Maestro BAL uses Air iQ to automatically detect and remove heat in the roof space to improve comfort and condensation risk. Air iQ adjusts fan speed for smart, high-performance ventilation and can be switched to a fixed speed motor for continuous ventilation mode if needed.
Fitting neatly to tiled or metal roofs, Maestro BAL roof ventilator uses a high-efficiency 24V DC motor to move air quietly and reliably. The aluminium body and malleable flashing make installs straightforward and durable, and the wide colour range blends with popular roof finishes.
