Question

An air compressor, having discharge pressure of 150 psi or lesser, is classified as ............... pressure air compressor.

• A. high
• B. low
• C. medium
• D. extreme

Hint:

Tip: Remember — up to 150 psi = low, 151–1000 psi = medium, above that = high pressure in typical industrial use.

Answer 1

The Correct Option is B

Air compressors are categorized based on their discharge pressure.
Compressors that deliver air at a discharge pressure of up to 150 psi (pounds per square inch) are generally classified as low-pressure compressors.
Low-pressure compressors are widely used for general-purpose air supply, small-scale pneumatic tools, and simple industrial applications.
Medium and high-pressure compressors operate at much higher pressure ranges, suitable for heavy-duty or specialized tasks like gas storage or high-power pneumatic tools.
The term “extreme” is not typically used in standard air compressor classification.
Hence, an air compressor with 150 psi or less is correctly classified as low-pressure.
