The blower room enclosure measured approx. 9.5m long x 7.8m wide 3.6m high, and was sat on a platform (supplied and installed by others), 4m above ground level. Acoustic panels for the platform floor were also supplied.
Inlet air for the blower plant was drawn through a large 5m wide x 3.6m high attenuator mounted on the side wall of the enclosure. The attenuator was extended out from the platform, and supported by means of a steel ‘goal-post’ frame.
Installation was undertaken on site, and required the use of a mini-crane for lifting of the components
The enclosure and attenuator were selected to reduce noise levels to 80dBA within the factory, in order to reduce noise to the first action level of the Control of Noise at Work Regulations 2015.
