the integrated air tool and pressure regulator assembly allows several air tools to operate from a single air compressor , using a simplified air hose distribution system . an operator may independently adjust the regulated pressure of the integrated air tool and pressure regulator assembly to compensate for varying working conditions . a greater air hose supply pressure may be used , as regulation of air pressure is accomplished at the integrated air tool and pressure regulator assembly . the increased air transport efficiency allowed by the integrated air tool and pressure regulator assembly of the present invention may provide for the use of smaller diameter hose , which may be lighter , more flexible , less costly , and the like .
