interesting. what is the ratio of this ? is it adjustable?
It's preset at 200-1. And will last for about 500 litres roughly.
So if you wanted to use vision in the injector, you would fill it up with pure water, and then just put about 5mill of vision into it.
If you want to use something else like virosol, then you would just put virosol neat into the injector (2 litre capacity). This would then dispense at 200-1 which is actually a very good ratio for all your standard PVC cleans and conservatories we've found.
You can then just disconnect the injector or fit a bypass and you will be back to using just pure. It means no more messing about with pump sprayers or backpacks to put chemicals onto whatever it is your cleaning, plus being able to use vision pure water additive even if you purify in demand through di vessels in your van.
