Pressure Capacity

Pressure capability in psi is largely based around the needs of the equipment the compressed air will be operating. While many air tools are designed to operate at normal shop air pressures, special applications, such as engine starting, require higher pressures. Thus, in specifying a piston compressor, for instance, a buyer would find a single-stage unit that delivers pressure up to 135 psi adequate for powering everyday tools but would want to consider a two-stage unit for special, higher-pressure applications.
