Pressure / Vacuum Gauge
It is important to know the operating pressure or vacuum level for the process in which the blower is being used. The most positive way to ensure your application is within the performance curve operating guidelines is to install a pressure/vacuum gauge. These gauges have service connections which allow them to be used to read either positive or negative pressure. In applications where pressure or vacuum may fluctuate, a gauge may serve to prevent future over-heating or overloading problems.
