Hi, I want to buy the Genx-2 upgrade "nx express" for my Direct port system, It comes with bottle warmer, purge, and a down blow tube, Does anybody here knows what the down blow tube is???

Thanks for all.

I think what it does it vent nitrous gas outside of the car in the event that the pressure inside the bottle gets too high. It should also come with a fitting and a little metal disc that you will need to insatll on the bottle.

Certain tracks require you to use a blow down tube, in order to pass tech inspection.

cburwell is correct.
you just run it out the car right next to the bottle.
have to drill a hole, most likely.

Yeah it's quite handy. I've had the bottle open before on me from too much pressure. Got 3rd degree burns on my hand from it.
