What is the Difference Between Compressor and Blower?

The main difference between a compressor and a blower lies in their pressure ratio, which is determined by the outlet pressure divided by the inlet pressure. Here are the key differences between the two:

Compressor:

• Operates at a high pressure-to-volume ratio.
• Crams air into a small space, making the trapped air denser.
• Releases highly pressurized air in a steady stream.
• Typically used for intermittent bursts of air or air that has been compacted, such as pneumatic drills, power tools, and air cylinders.

Blower:

• Operates at a low pressure-to-volume ratio.
• Continuously moves large volumes of air for a moderate increase of pressure.
• The direction of the air being pushed by the blower can be changed by making changes to the blade.
• Used for applications that require steady airflow, such as forced hot air furnaces and hair dryers.

In summary, air compressors deliver air with a high pressure-to-volume ratio, while air blowers deliver a larger volume of air with lower pressure. This means that they tend to be used for different applications in various industries.

Comparative Table: Compressor vs Blower

The main difference between compressors and blowers is the pressure ratio. Compressors operate at a high-pressure ratio, while blowers operate at a low-pressure ratio. Here is a table summarizing the differences between compressors and blowers:

Compressors are used in applications that require high pressure, such as powering air tools, paint sprayers, and abrasive blast equipment, while blowers are used for applications that require a larger volume of air with lower pressure, such as HVAC systems and cooling and drying systems.
