ST-2315 Assembled Downstream Gun

This pressure wash gun is built to handle chemicals associated with spraying a downstream mix. This gun comes completely assembled with stainless steel quick connects and a 6” stainless wand. The 6” lance helps straighten the water just enough coming out of the gun. There’s no need for heavy bulky pressure washing guns. Tested and tried for 6 years in our own previous wash business.

The ceramic ball inside doesn't care about sodium hypochlorite, and the 12 GPM-rated body doesn't choke a big machine's draw the way small homeowner guns do. Pair it with the M5 Twist downstream nozzle sized to your machine. Not sure what injector, nozzle or bleach mix your rig needs? Our downstream calculator works it out from your GPM and hose length, and the complete downstreaming guide covers the rest.
