What type of air compressor would operate within the range of 151 psig to 1000 psig?

The correct answer refers to a compressor that operates in a range considered typical for medium pressure applications. A medium pressure air compressor generally works within limits that span from a minimum of about 100 psig up to around 1000 psig. This type of compressor is utilized in various applications, including pneumatic tools, pressure testing, and certain industrial processes, supporting operations that require a moderate pressure output.

High pressure air compressors are designed to exceed this range, typically going above 1000 psig, making them suitable for specialized tasks like filling high-pressure gas cylinders or providing air for certain types of advanced equipment. Low pressure compressors, on the other hand, operate well below 151 psig, focusing on applications that do not require high pressure outputs, such as blowing or cooling. Vacuum systems also do not operate within the psig range since they work to create a negative pressure environment rather than positive pressure, thus serving entirely different functions.
