Smart roof ventilator with bush fire rating up to BAL-40. Removal of roof space heat and the management of moisture and damaging condensation.

Maestro BAL is a powerful mechanically driven ventilator that continuously and reliably improves the comfort and health of your home all year round. In addition, Maestro BAL is assessed by the CSIRO to be compliant with the fire rating requirements of AS3959-2009 up to BAL-40.
The high quality aluminium based ventilator provides four speed settings (automatic, low, medium and high) to manage excess heat and damp in the roof space, providing a more comfortable and healthier home, while complying with a ventilator required for a bush fire area..
One Maestro BAL is equivalent to six wind driven vents and can be used on a continuous and reliable basis, without reliance on the wind.
The quiet motor and low cost to run make this ventilator a valuable addition to the comfort level in your home. In addition, the Edmonds partnership with Sensitive Choice (National Asthma Council) shows the support for Maestro BAL as a provider of better quality air, especially for those suffering from asthma and allergies.
