Hi Peter
The purpose of these vents is what they are made for, to face forward, draw air into to space area that they are attached and pressurize that cargo area. When the area is pressurized, the air then is forced out of the point where there is little sealing, the back tail
gate, therefore forcing the dust from entering the back of the vehicle. It is very clear that Wato's unit is fitted wrong, that is why the back of his cabin space was covered in dust. I do not even know why he has asked for photos, as I answered his original post a couple down.
You only have to look at dual cabs that have vents fitted, and I have never seen one fitted facing towards the back. It sounds like Watos was a
home made job, as a good number of years ago when I was a spare parts manager at the local GM dealer, we fitted dozens of these units to many four wheel drives, and the clear instructions given, make it very clear that the units must face the front, and not to be used at speeds over 100 kph.
The very same principal applies to driving on dirt roads with conventional vehicles. Set you fresh air intake to drawing fresh air into the vehicle cabin area, not recycling and you will see a very big difference with dust ingress inside the vehicle, working in the same principal, forcing air out through the door seals.
Cheers
Stephen
