How fast is the dryer?

So, how fast is a typical blow dryer at the end of the tunnel?

I did one of those "Tornado" experience box in the malls where you go in a telephone booth size box and it creates wind speeds up to about 75mph. I tried to compared that to stadning underneath our tunnel dryer. Our tunner dryer seems to be a bit more stronger but not that much more. So I thought maybe 90mph at tops. What do you think?

It's gonna depend on the horsepower of the motor and the nozzle that the air is exiting, having said that their are blowers that are capable of probably moving air at close to 200 mph. My guess is that most blowers are somewhere between 90-120mph.

I see. The reason why I asked is whenever a piece of some sort falls off of a car going through the tunnel, many seems to be because the blower blows them off. But I'm thinking that the blower isn't any stronger then you speeding on Interstate. I guess the reason the blower can still blow things off is because it shoots in all direction?

This is a good question, I agree with you Tom. I can't imagine it being more than 90mph. I am sure there are exceptions aka overkill. I would think it depends on the opening in the dryer, which would determine the concentration of air flow. Obviously the horse power is a factor. So at a particular point it may be above 120mph. But overall, at the point where it reaches the car it is significantly lower, closer to that 80-90 mph mark.

I don’t know though, are there any dryer experts in the building?

Sorry, John. I pretty much restated what you did...

In my view, SPEED (velocity) is not the primary factor in assessing efficacy in drying a vehicle. Rather, air VOLUME also has a significant impact in the drying process, as does angle of impingement of air on a wet surface.

In fact, more velocity may create counterproductive turbulence if impingement and volume are lacking. That's why more air nozzle outlets provide a greater potential for effective low=velocity drying.

I think he was more or less curious about the comparison of a car in his tunnel vs a car driving on the road, and putting a number to it. What would you say if you had to put a mph on it Steve?

our blowers at CANTON AUTO WASH are well known as the most powerfull in michigan, ive been in the biz for over 15 years , nothing comes close.

my best geuss is 160+ mph .

1170 sq inch of ducts.
i have blown out bed liners, bumper supports , and a few steel shovles .

and they do not touch car. best part there for sale !!! im upgrading to all stainless.

Wow, I'd love to buy something that blows bed liners and steel shovles into oncoming cars. Who do I call?

lol

Sonnys! my 120hp will also blow out rubber bed liners, steel and snow shovels, we are extremly strict when it come to empty beds! We have a large collection of these items stock piled up
