Pumps, Compressors, Blowers and Fans - Engineering ToolBox

Why are you capitalizing all the nouns and verbs, and misspelling "their"?

In rough terms, a fan increases pressure and decreases volume by a small percentage.
A blower does the same by a larger percentage, a pump a still larger percentage, and a compressor yet larger again.
The dividing lines are inexact and overlapping, and depend on local terminology.

Hello Cr4 people

- compressors are used for gases only and it rises the pressure, depending upon the system.

compressors uses are : In refrigeration, Oxy. and Nit. gas planet that required a high pressure compressors, air compressor for tires filling and.....etc

- Blowers are used for air - as Mr. Tornado said - increases pressure and decreases volume by a small percentage.

Blowers uses are: In Ventilation for huge Store Houses which blow the air to inside the place to renew the air inside the store, also in some types of furnaces that needs blowers to supply air, portable blowers used in superficial cleaning in some places that need to blow the dust off .

But ... Pumps doesn't ever work gases
