Australian Consumer Law

• Our goods come with guarantees that cannot be excluded under the Australian Consumer Law.

You are also entitled to have the goods repaired or replaced if they fail to be of acceptable quality and the failure does not amount to a major failure.

The integrated PerfectAir sensor continuously measures cooking vapours and automatically adjusts extraction performance to maintain effective ventilation while minimising unnecessary fan noise. This allows the rangehood to respond dynamically to changing cooking conditions without requiring manual speed adjustments.

The DWB91PR50A supports Bosch Home Connect functionality and compatible cooktop-based hood control, allowing selected Bosch cooktops to automatically communicate with the rangehood and adjust extraction settings based on cooking activity.

For kitchens where external ducting is not practical, the rangehood can be configured for recirculation using Bosch compatible CleanAir recirculation accessories available separately.
