ROBOKIM #1 INJECTOR 2.9-4.0 GPM 2.2mm

Downstream injectors are installed after the pump. In order to function, the pressure must be lowered with the use of either a dual lance and soap nozzle, a variable nozzle, a dual nozzle holder, or an adjustable nozzle holder. Water enters the inlet of the injector and creates a venturi which drops the pressure and suctions the chemical from container. Chemical can be injected either in concentrated form or in diluted form. Chemical can be regulated by turning the dial on the injector or installing a metering device on the chemical line. The injector contains a check valve to prevent water from flowing into the chemical container while in high pressure mode.

NOTE: Length of hose will determine ability of injector to work properly. It is recommended to keep hose length at 100 feet or less.

Refer to the arrow on the injector body for proper flow direction. Install the injector in the system downstream of the regulator unloader which is downstream of the pump. These injectors will draw your chemical into the water stream at 125 PSI and 2.1 to 10.8 GPM, through your low pressure nozzle. Injector WILL NOT draw chemical above 250 PSI through your high pressure nozzle. The amount of chemical drawn in is controlled with the adjustment knob.

• Maximum pressure: 3200 PSI.
• Maximum temperature: 210 degrees F.
• Inlet port: 3/8" MPT.
• Outlet port: 3/8" MPT.

Thank you for browsing our selection of pressure washers, steam cleaners and accessories.

We have the tools you need to effectively use and maintain your pressure washer.  Quick connect and rotating turbo nozzles are available in various sizes and configurations.  It's important to use the proper size nozzle for your pressure washer.  Nozzles are sized by looking at the PSI and GPM of your pressure washer.  Quick connect nozzles make it easy to change spray patterns or replace nozzles when they are bad while using the same spray wand.

Pressure washer hoses and hose reels will help you reach your work area, and specialized spray guns with different angles and lengths of wands will make certain jobs easier.

To keep your pressure washer working properly, routine parts and maintenance could be required.  Pressure washer pumps, unloaders, and motors should match the specifications of your particular machine.  Hot pressure washers and steam cleaners require additional components like burners, ignitors, and fuel pumps to allow them to heat the water.

There are a number of different accessories for your hot or cold pressure washer to clean different areas.  Surface cleaners are great for cleaning large areas like parking lots, gas stations, industrial facilities, and school yards.  Duct cleaners are designed to clean trash-chutes, vents, ducts, restaurant hoods, tanks and more. Wet sand blasters can be used on various surfaces to remove most coatings down to white metal, for graffiti cleaning, or paint surface preparation.
