AutoFoam Around-the-Pump

The AutoFoam around-the-pump system provides complete automatic proportioning for Class B foam. The operator selects a foam percent mixture and the solution provides a consistent foam solution at all discharges regardless of water flow fluctuations. A microprocessor controls the proportioning valve to automatically maintain accurate control over foam concentrate flow rates. The operator can override automatic operation by using the manual override buttons to control the proportioning valve. All operations, programming, and calibration are accomplished using the control module. Calibration for the system is stored in memory on each of the major components. This allows for the replacement of components without recalibration of the system.
