All large scale compressed air needs to go through a drier. When you
compress air it warms up. Warm air has a better ability to hold moisture.
Once it cools then the moistures condenses out. Even with that you still
need point of use separators where equipment needs dry air. The air
continues to cool as it travels to point of use.

A small home compressor can be the oiless variety but if you are at a
manufacturing facilty like me that is not the case.

That is why I like the blower. Easy to use and no about moisture, oil and
you don't need a compressor.
