Evaluation of 95 gpm Inductors for Aqueous Film Forming Foam,
Abstract
The 95 gpm in-line inductor is being considered as a replacement for the portable FP-180 water motor proportioner which dispenses Aqueous Film Forming Foam (AFFF solution) for fire fighting purposes. The inductor has no moving parts and will produce consistent results dependent upon inlet pressures. The purpose of this project was to test and evaluation the performance and efficiency of five commercially available inductors with regard to concentration of AFFF produced, nozzle pressure, and flow rate across a range of inlet pressures ranging from 75 psi to 200 psi. All units performed satisfactorily. Two units, however, which had longer outlet throats and taper of 7 deg demonstrated more efficient performance than the other units. It is recommended that a MIL SPEC be written to incorporate specific features of these units as well as additional changes necessary to provide a reliable unit for shipboard use. (Author)
