The Silencer kit

This simple, efficient and durable foaming system features the Suttner ST-160 Foaming Injector and the Suttner ST-75 Foamer. This system solves the biggest problem with all foam cannons which is the refills by injecting the chemical at the outlet of the power washer. The ST-160 utilizes dosing nozzles for automatic dilution with a range of 10:1 to 200:1, completely eliminating all guess work when it comes to the strength of your soap. We set these injectors to draw at 100:1 which is 1% of the GPM, perfect for our super concentrated soaps. This equals 4-5 times less soap than standard injectors. Not only do you get the benefit of efficiency but you also get further cling time allowing work on larger areas and less soap run off.
 
This professional but affordable package is completely plug and play. To install, plug the ST-160 Injector onto the outlet of your power washer. To engage foam mode, attach your ST-75 Foamer to the gun or lance outlet. To switch back to rinse, reattach your rinse nozzle.

      How to Install

      1. Connect ST-160 injector after power washer and before your high psi hose. The ST-160 will be made ready with a stainless 3/8" quick connect plug on the inlet and a stainless 3/8" quick connect socket on the the outlet.

      2. Place chemical pick up tube directly into soap.

      3. Foam all of the things!



      • Injector will be set to run at 100:1 unless specified otherwise, this can be changed by simply changing metering tip inside injector barb.
      • If using a hot water machine, scale build up from your coil can plug injector or foam head. On start up always run with injector in rinse mode for about 30-60 seconds to flush out any build up.
      • If a jumper hose is needed to go from your power washer to ST-160 injector please see our selection of hoses.

      Figure out Your current rinse nozzle size

      Use the chart below to figure out your nozzle size. You will need your power washer's current GPM and PSI. This information is usually found on a sticker located on your machine.

        Foam, Foam, and more Foam

        After looking at the overall presentation I was skeptical, wondering if I could achieve the same results. Nevertheless, I have no more skepticism...I used the silencer kit on 80 box truck units. Originally what took me a day and a half was cut short. Due to the efficiently of not having to refill a 1.5L foam cannon, I was able to cut my time in half. I will be making a second and third purchase for my other rigs. And if you want to know how the Silencer kit compares to a foam cannon... the lather is thick and stays on longer, you can choose the dilution ratio easily which works well if pulling a pure concreate in a 5Gal, 30Gal, or 55Gal container. 5 Starts - Red Drum Power Clean - Houston, TX
