General Pump High Draw Downstream Injector

General Pump high draw fixed downstream injector in three sizes for 2 to 8 GPM pressure washers.

These fixed downstream injectors from General Pump are the most popular injectors for house and building washing, and you can also use them for post-treating concrete. These are the injectors I use every day.

Pick the size that matches your machine's flow rate: 1.8 mm for 2 to 3 GPM, 2.1 mm for 3 to 5 GPM, or 2.3 mm for 5 to 8 GPM.

Keep a Backup on Hand

Downstream injectors will eventually fail, so be sure to order a backup or two so you can keep on working. As with anything bleach is run through, there is no warranty or guarantee on how long an injector will last. Backups are very important in this business.

Works With

We use these injectors in our Downstream Injector Kit and our Downstream Bypass Injector Kit.

For an even higher draw rate, add our Check Valve for Downstream Chemical Injectors. These are the only injectors compatible with that check valve. Your draw rate can be affected by pressure, flow rate, hose length and chemical viscosity.
