Compressor Flexible Mountings

The compressor and its prime mover should be mounted on flexible supports, preferably on a massive base also. Certainly the enclosure should be isolated from the machine proper, otherwise its value as a barrier would be lost. There may be difficulties if the pipe work is rigidly attached to a compressor free to move on its supports, so flexible hoses or bellows should be interposed.

There are several types of isolator on the market. Simple composition pads have a small static deflection but present a high impedance to high frequency energy. Rubber mounts have a medium degree of static deflection, suitable for lower frequencies. Steel springs, and in severe cases air springs, can be used for very low frequency isolation.
