Has anybody used a vacuum tanker pump to blow off a combine.

As title.
It strikes me that they are easy to get hold of, have a pto shaft, run at 540, and produce a lot of air (over 200cfm). Is the pressure high enough to push that air down a 1 inch hose to blow off a combine for example?

would make a good volume washer maybe

Never tried that
But it's similar concept to a hydrovane compressor

Not out of the tank it wont unless you can hold on to a 4 inch pipe
Not enough pressure for the flow

i meant if you reduced it down to 1"? be similar to a volume wash in a parlour wouldn't it??

Go on then, fill the tank up in till the 1bar PRV goes off. Reduce the 4” outlet to 1” and then hold on to the pipe and open valve. I would guess it would be awesome for a minute or so!!!

Get a tanker complete, then you'd have a tank full of air in reserve, 1500 gal at 15psi is a lot of volume, keep the tanker a third full of water to catch the dust and it will act as a vacuum cleaner as well.

No,only 15psi

I've got a tanker, thats what gave me the idea.
Its too big to tow behind the pickup, and doesn't cart grain either.
I just thought I could buy a pump(£1500), mount it on a 3pt linkage frame and then it will be available in the field.
Just not sure if the air volume and pressure would work.

Flow Rate Calculator - Pressure and Diameter | Copely
with the best will in the world you be lucky to get 50 liters a minute at 1 bar from 25mm pipe at 10m long

Plenty of second hand hydrovane compressors knocking around for that money if you look hard enough.

One equipped with a Garda pump would

I have used a tanker with a 2 inch or so hose, it's pants. Pours out rather than flies out.

If you live near houses of parliament connect hose to that, so much hot air it would Blow the bl--dy doors off..............
