3.5 The NAT Vent - Installation

The NAT Vent Attenuator is an attenuator specifically designed for low energy buildings. This product allows for cross ventilation through a partition without downgrading its acoustic performance. To meet the acoustic and ventilation requirements, MACH Acoustics designs and tests attenuator configurations using our in-house test facility, such to meet the individual needs of a building. Please see our website for further details: www.machproducts.co.uk

The NAT Vent Attenuator is constructed using foam blocks which tessellate together to form this product. A range of raw materials can be selected to acoustically adjust its performance. In addition, materials can be selected to the meet fire (Class O) requirements of recycled content. To control air flow and prevent the spread of fire, the NAT Vent Attenuator is often combined with volume control and fire dampers.

The installation of the NAT Vent Attenuator is exceptionally simple; the foam tiles are pushed into a bulkhead formed from timber or metal. Timber bulkheads can be lined with plasterboard. If the NAT Vent Attenuator is supplied in a metal duct, it can be simply supported on uni-struts to hold it in place.
