Quiet Compressor Development

CompAir quiet compressor devlopment

As part of a continuous product development programme to maintain their world-leading reputation, CompAir asked us whether it would be feasible to re-design the noise control package on one of their compressors. The initial target was to remove the existing silencer element to reduce the overall size of the unit – without any increase in noise or a reduction in the performance of the cooling system.

Source control modifications were developed for the cooling system which significantly reduced the overall noise from this element at source and also dramatically cut the tonal content (less “nuisance”). Coupled with modest flow and geometry changes, the new package reduced the overall “headline” noise from the compressor by 2 – 3dB(A), despite removing the standard silencer – and all without any cost or performance implications.
