Rotary air compressors: typical maximum delivery pressure What is a representative maximum delivery pressure achievable with rotary air compressors (e.g., roots/rotary screw) in single-stage practice? Choose the correct option.

Concept/ApproachRotary positive-displacement compressors (roots, screw) are well suited to moderate pressures and high flow. Typical single-stage delivery pressures are around 10 bar. Higher pressures are usually attained using multi-stage reciprocating machines.

Final Answer10 bar
