Designed to provide quiet and efficient air extraction from bathrooms, toilets, dryers and rangehoods, where there are confined ceiling and wall spaces. This allows Mechanical Engineers and Architects a more flexible design where space for services becomes limited.
Available in three sizes to suit a large range of airflow and low resistance requirements, at low noise levels to maximize fan performance.
All low profile ducting sizes have been independently tested and complies with Australian Standards a 4254.2-2012: Ductwork for air-handling systems in buildings. 2.1.2 Rigid ductwork.
Testing has been completed and is compliant to AS/NZS 1530.3 to have smoke development index no greater than 3 and a spread of flame index no greater than 0. All ducting has passed a UL181 burning test.
