Has anyone ever built or bought an insulated box to reduce the sound of a portable air compressor? I have an oil-less pancake style compressor that is very noisey. I would like to enclose this to make it quieter. I think that it would need to be vented on 1 or 2 sides to keep the compressor from overheating. Unsure if this thread is posted in the right area but this compressor is used for maintaining equipment.
