- Downstream Injector: A downstream injector, also known as a chemical injector or soap injector, is a device that connects to the pressure washer’s pump. It is typically attached to the low-pressure side of the pump and draws chemicals or detergents into the water stream after the pump, downstream from the high-pressure pump output. The injector uses the pressure differential created by the water flow to draw and mix chemicals into the water stream. This allows for the application of cleaning agents, detergents, or other additives during pressure washing.
- X-Jet: An X-Jet (pronounced “ex-jet”) is a specialized type of downstream injector. It is a handheld, adjustable nozzle system that incorporates a chemical reservoir. Unlike a traditional downstream injector, the X-Jet does not connect directly to the pressure washer pump. Instead, it utilizes the pressure washer’s high-pressure spray to create a siphoning effect, drawing chemicals from the reservoir into the water stream. The X-Jet allows for on-the-fly adjustment of the chemical concentration by altering the nozzle’s position, enabling the user to apply different strengths of chemicals as needed.
- Connection: A downstream injector connects to the pressure washer’s pump, while an X-Jet is a standalone nozzle system that does not directly attach to the pump.
- Chemical Mixing: With a downstream injector, the chemicals are mixed with the water downstream from the pump. In contrast, an X-Jet has a reservoir that allows for adjustable chemical mixing using the high-pressure spray.
- Portability: Downstream injectors are typically fixed in place and require a connection to the pressure washer. X-Jets are handheld and offer more mobility since they are not directly attached to the pressure washer.
In summary, a downstream injector is a separate device connected to the pressure washer’s pump, used for injecting chemicals into the water stream downstream from the pump. On the other hand, an X-Jet is a portable nozzle system with an integrated chemical reservoir, utilizing the high-pressure spray to draw and mix chemicals as needed.
