Downstream Fixed 20% Draw 5 – 8 GPM Chemical Dual Barb Injector - Assy ACI791

Overview

The ACI791 is a fixed 20% high-draw downstream chemical injector assembly for pressure washers running 5–8 GPM, rated to 4500 PSI maximum. It installs after the pump and before your 3/8" high-pressure hose, pulling soap at low pressure so chemical never runs through the pump — which protects your pump seals and lets you use a wider range of chemicals. The dual barb brass inlet feeds from two included 4-foot hoses with strainers, and the fixed 20% ratio gives you strong, consistent draw without adjustment. Spray soap through a size 40.0 nozzle — black tip for short range or blue tip for long range. Quick-connect fittings make it easy to snap on and off between jobs.
