What is a downstream injector on a pressure washer?
A downstream injector is a device used to inject chemicals or detergent into the flow of water after the pump on your pressure washer. This differs from an upstream injector which injects chemical before the pump.
What is a 2.1 downstream injector?
The soap injector allows you to apply soaps or cleaning chemicals at low pressure through your pressure washer. These downstream injectors are designed to apply chemical only when running under low pressure (250 psi or less). 2.1 size is for use on pressure washer with 3.0 to 4.9 gallons per minute.
How much does a downstream injector dilute?
In order to use a downstream injector, the end solution of the chemical being applied must be effective at dilution rates of 8-1 and higher.
Can you use bleach in a downstream injector?
Solution: Use a typical 20 / 1 venturi style chemical injector. Do not exceeded 150 feet of pressure hose. Your 20/1 downstream injector will now pull the bleach and Green Wash solution through and your final cleaning solution at the wands tip will be . 06% bleach to water or about one half of a percent overall bleach.
How do you test downstream injectors?
Test your upstream or downstream injector by getting a metering jug that measures ounces and fill it with water and put your soap line into the metering jug and draw the water for 1 minute. This will allow you to see how many ounces your soap injector is drawing in a minute.
What does downstream mean in pressure washing?
Downstream injection is a means of applying chemicals with the use of a pressure washer. Downstream injection introduces chemical into the system after the pump, so no chemical is ran through the pressure washer pump itself.
What ratio is a downstream injector?
Downstream injection is a means of applying chemicals with the use of a pressure washer. It is an effective way of applying chemicals, as long as the end solution of the chemical being applied will be effective at dilution rates of 8-1 and higher. Dilution ratio depends on the GPM of your pressure washer.
Should you dilute pressure washer detergent?
Hello from Karcher – yes, most detergents for pressure washers are concentrated – typical dilution is 20 parts water to 1 part concentrated soap and be sure to mix it outside the soap tank first then fill the soap tank.
What does Downstreaming mean in pressure washing?
How does a downstream injector in a pressure washer work?
Downstream injection introduces chemical into the system after the pump, so no chemical is ran through the pressure washer pump itself. A downstream injector works by maintaining a certain PSI on the pump side of the injector by means of an orifice installed into the injector body.
What kind of injector do I need for pressure washer?
In this situation it is best to use a 3-5 GPM rated injector. The pressure drop in the hose that draws your pre-mixed chemical solution is created by changing your pressure washer’s nozzle to a large orifice nozzle (aka a soaper nozzle).
What happens when the PSI of a pressure washer drops?
When the PSI drops by at least a 30% differential on the outlet side of the injector it creates a vacuum draw that pulls your pre-mixed chemical solution into the injector body and mixes it with the flow of water traveling through the injector and out the hose and gun assembly of the pressure washer.
