Pneumatic air systems for use onboard aircraft include a compressor (102) configured to receive air from an air supply (108) and increase a pressure of said received air to generate compressed air, a heat exchanger (112) configured to receive the compressed air as a first working fluid and a treating air as a second working fluid, the heat exchanger (112) configured to convert the compressed air to compressed and temperature treated air, one or more aircraft systems (114a-c) configured to receive the compressed and temperature treated air, and a surge prevention circuit (138) arranged to prevent surge of air at the compressor, wherein the surge prevention circuit (138) comprises a mechanical valve (140) that is actuated based on a detected pressure within a sense line (142) operably coupled to the mechanical valve (140).
