If a compressor makes noise in the woods does anyone care? Probably not, but when they have to be placed by patios, under bedroom windows or in community gathering areas, the noise just seems louder. Every 10dB decrease is actually as loud to the listener and normal conversation is in the 60-70 decibel range the same as our cabinets without the new sound kits! Now there are options to give your customers the best experience for their circumstances, the Vertex Sound Kit which consists of a Muffler Box, Sound Insulation and a Quiet Filter. This option is available for all sizes of Vertex QuietAir Cabinets.
