The 2-Way 105HC Filling Station has a water flow rate of 1 GPM @ 40 PSI and is a "high concentrate" 2-chemical or two ratio proportioner for filling smaller containers with strong solutions using a trigger gun. This venturi injection system uses city water pressure (40 - 80 PSI) to draw and blend a high concentration of chemical into the water stream to create up to 1:1 dilution ratios.
