The blowoff system in question

No I’ve seen those air knives used to blow of water really good stationary so imagine them getting close to the car.I didn’t see any information regarding how much air is being moved (CFM). I suspect if this type of system was practical some manufacturer would have adopted it. This system looks to be similar to Protovest “Stripper” and several other systems with a movable/profiling top blower.
I suspect the airflow to blow dust off is wildly different than the airflow needed to move water droplets.

About that they offer a fully articulated version that flips the top contour nozzle 90 degrees and from the description it says the also offer side articulation. Which from my guess means the rotate and move in and out, and about the cfm it gets close to the car with a high pressure ionized nozzle so the cfm is no problem ether.They can work, but it’s all about CFM and nozzle angle
