Steven Levy Enterprises buys and sells new, unused, and used surplus gas compressors. Browse our inventory of used gas compressors available for purchase. Gas compressors work by mechanically increasing gas pressure in stages (or steps) until it reaches the desired delivery point. The starting pressure and the desired ending pressure will determine how many stages a compressor will have. Gas compressors are used to compress the volume of the natural gas thereby increasing its pressure. This enables the natural gas to easily flow to long distances within the large trunk pipelines without any drop in pressure.
