The Maestro BAL bush fire rated roof ventilator has an aluminium dome and housing with a built in sparkguard mesh and frame which makes the fan suitable for installation in bush fire prone areas. The fan has a high quality Electronic Commutating (EC) motor that comes complete with a transformer. Via the transformer you can select the low, medium or high speed. There is also an ‘auto’ function. The cable provided with the transformer is approx 10m in length, which means your powerpoint needs to be within 10m of the unit. If you have an available power point that can be reached then no electrician in required. If a power point is unavailable then an electrician will be required to install one.
How the Automatic Function Works
The variable speed response is relative to ambient temperature and humidity in the area where the speed controller is located. The fan starts on LO speed when temperature reaches 30°C and then ramps up to HI speed at 45°C. For humidity, the fans will start at LO speed when humidity reaches 65%rH and will increase in speed until MED speed is reached at 80%rH.
Speed | dB(A) | Power (W) | Capcity (m3/hr) |
Low | 35.4 | 4.8 | 220 |
Medium | 45.1 | 11.2 | 377 |
High | 52.9 | 30.8 | 596 |
