What term is sometimes used as an alternative name for air compressors?

The term "air pumps" is commonly used as an alternative name for air compressors because both devices serve to increase the pressure of air and move it from one place to another. Air compressors work by reducing the volume of air, which in turn raises its pressure, making it suitable for various purposes such as powering pneumatic tools, inflating tires, or supplying air for breathing equipment.

The use of "air pumps" highlights the function of the device as a mechanism that pumps air into a given system, emphasizing its role in moving air under pressure. This term is widely recognized and understood in both industrial and everyday contexts, making it a suitable alternative.

Other terms listed do not accurately describe the function of air compressors. For example, "air turbines" refer to a different technology focusing on the conversion of wind or air flow into mechanical energy, rather than compressing air. "Air filters" are designed to remove impurities and particulates from the air rather than compressing it. Lastly, "air generators" typically imply the generation of air or oxygen, which is not synonymous with the role of a compressor.
