The Differences Between An Air Pump And An Air Compressor

In most settings, and particularly in an industrial setting, people often confuse an air pump with an air compressor. Considering the fact that both control air by force, it is easy to see how they might be confused. However, there are some significant differences between the two, and it is important to know these differences when it comes to installation, repairs, and replacement of these two air-related pieces of equipment.

An Air Compressor Compresses Air

​An air compressor compresses air. What that actually means is that air is forced into a very small, very tight space, until all the molecules of air are packed so close together and so densely that almost nothing can squeeze between every molecule of air. This creates intense pressure. That intense pressure needs a release, or it can blow up. Thankfully, compressed air is created for the express purpose of using the air to rapidly fill things like tires or other inflatable items, or with the use of tools that rely on compressed air to function.

​Air Pumps Create and Release Air as It Is Created

Conversely, an air pump is a motor that pumps air into a space. It does not compress the air at all. It merely creates air for the purpose of pushing gases or liquids along through the factory to other tanks or to create a means of mixing substances with air only. Additionally, most industrial air pumps are significantly larger than compressors used in the same factory because the air pump engines have to work harder to create air as its own force rather than compressing and releasing it. 

​Air Compressor System vs. Air Pump Installation

​Air compressor systems in a factory or industrial setting are installed such that there are one or two compressors attached to a series of pipes and hoses that wrap around short distances in the plant. They are designed to deliver the compressed air in short bursts. Trying to make the compressed air travel greater distances often results in decreased air pressure, which does not make things work well. Air pump installation, on the other hand, occurs in one part of the plant, and the machine delivers constant flow of air over longer distances with continuous, steady force. The air is delivered via pipes directly to all the areas of the plant where air is needed to perform ongoing specific tasks that do not need pressure from compressed air.
