Special gas compressors are a machine that
compresses a gas to raise its pressure. These are a pump that transports gas
from one location to another. Positive displacement compressors and dynamic
compressors are the two different categories of gas compressors. The way that
positive displacement compressors operate is by first trapping a volume of gas and
then reducing it. The gas is now under more pressure as a result. An impeller
is used by dynamic compressors to accelerate the gas. As a result, the gas
flows into a smaller space, increasing the gas pressure. Special gas
compressors come in various specifications.
