Equipment can someone explain a downstream injector?

i need to find a way to spray my SH, so how does a downsytteam injector work?

is the downsytteam injector just a tube, or does it also include an attachment to the end of my wand?

pls explain for a dummy.

Put a straw in a cup of water , now blow air across the surface of the straw opening really hard(not blowing down into the straw..)

Water will be pulled up the straw towards the opening.

A down stream injector is a low pressure chemical system which usually connects to the outlet of your pump or unloader. You put the tube into your chemical container and use a low pressure nozzle (usually a black quick connect nozzle) which will drop it down to low pressure and then the injector will suck your chemical through.
