Difference Between Air Compressor and Regular Compressor?
An air compressor and a regular compressor can refer to different types of machines used for distinct purposes. Here are the main differences between the two:
1) Medium Compressed:
Air Compressor
This type of compressor specifically compresses air. It takes in ambient air and compresses it to a higher pressure, which can then be used for various applications like powering pneumatic tools, filling tires, or even in industrial processes.
Regular Compressor
“Regular” is a bit ambiguous, as compressors come in various types designed for different mediums. They can compress gases (not just air), liquids, or even solids in certain applications. It depends on the specific use case, but a “regular” compressor might not be limited to air as the working medium.
2) Applications:
Air Compressor
Primarily used for generating compressed air for pneumatic tools, painting, inflating tires, HVAC systems, and various industrial processes.
Regular Compressor
Depending on the type, it can be used for a wide range of applications, such as refrigeration (for compressing refrigerants), gas compression (e.g., in natural gas processing), oil refining, chemical processes, and more.
3) Design and Build:
Air Compressor
Generally designed for specific air compression needs, often portable for smaller applications like inflating tires or powering small tools.
Regular Compressor
The design depends on the medium being compressed. It might need to handle higher pressures and different materials, making it more specialized for specific industrial applications.
4) Pressure Levels:
Air Compressor
Usually designed for lower to moderate pressure ranges suitable for pneumatic tools and general-purpose air-powered equipment.
Regular Compressor
Depending on the application, it might handle much higher pressures, especially in industrial settings where the compression of gases or liquids is involved.
Difference Between Air Compressor and Air Pump
An air compressor and an air pump are both devices used to move air, but they serve different purposes and have distinct differences in their design and functionality:
