Normally if you want to set up water tanks in the van, you need an additional pump to carry water from the external tank to your machine. But not so with Airflex. Airflex can hook up and draw cleaning solution from external tanks, with no extra pump required.

So if you want to run your Airflex direct from the van, simply drop Airflex's direct feed hose into any external water container and you're ready to go.
