Fixed Chemical Injectors for Pressure Washers

Apply cleaning chemicals safely and efficiently with fixed downstream chemical injectors designed for pressure washing applications. Fixed injectors draw chemical at a preset ratio, providing consistent chemical delivery without pump exposure for house washing, concrete cleaning, and general pressure washing tasks.
