Poor ventilation associated with damp and stale air, causes a number of unhealthy living conditions with condensation and mould, along with increased costs of building maintenance caused by damage to interior surfaces.

Australian & New Zealand Standards require a minimum airflow rate for toilets, bathrooms, ensuites and toilets of 90 m³/h (25 l/s). These standards however aren’t adequate to remove steam from bathrooms and ensuites when a shower is being used, and the recommendation is between 252 – 324 m³/h (70 – 90 l/s).


In Australia venting a ceiling fan into a ceiling space is not allowed, where a metal roof has sarking or is lined, unless the roof space is ventilated through roof vents or grilles in the soffit. The professional recommended method for ventilation of all stale and damp air, is for it to be ventilated to the outside of building.


Blauberg fans comply with the Building Code requirements of Thermal Performance, by including a backdraft damper in the majority of our fans. This is designed to seal off the fan when not in use. Backdraft dampers are available as an accessory for code compliance.

Blauberg Ventilation offers an extensive range of German designed and manufactured ventilation options, designed to comply with Australian and New Zealand Standards when installed correctly. Installation of ducting must be cut to the correct length, and be tight and straight. Failure to do this will greatly reduce the performance of your ventilation system. Correct selection and installation will remove stale, damp air making sure you home remains healthy and inviting.
