* Diameter, height and weight may vary slightly without notice.
** In keeping with current industry standards, drawdown factors are based on Boyle's law. Actual drawdowns will very depending upon system variables, including the accuracy and operation of the pressure switch and gauge and operating temperature of the system. |
