GPM (LPM) NOTE |
Eductor and nozzle must have matching flow rates (gpm/lpm) for the foam concentrate to “pick-up.” |
Operating Pressures of Eductors |
These eductors are designed to achieve rated flow with an inlet pressure of 200 psi (150 psi for the 242-95). They will operate at lower inlet pressures, but the flow rate and percentage rate will be affected. |
