There is also a commercial implementation available called Berd Air.
If you connect anything other than a brushless DC fan to a fan output of your electronics, connect a flyback diode in parallel with it to protect the fan mosfet.

An axial fan is not able to create the kind of pressure you need. Even a stronger radial fan won't help, it will need a pump. The fan will just sit there creating turbulences. Fans are meant to move large volumes at low pressure. Pumps are meant for low volumes at high pressure. The smaller the diameter of a pipe the higher the pressure you need to transport any usefull volume of air.Quote

What about using a 140mm fan with an air duct blowing air into the tubing instead of a pump? This would make it easier compared to a mains powered aquarium pump.

One thing to note with ring-type blowers that attempt to blow air at the nozzle from all directions, by virtue of symmetry, the air velocity right at the nozzle tip must be zero.

Is it something like this [www.sparkfun.com] ? or much stronger?Quote

CPAP machines use turbine type blowers with brushless DC motors.

Why not turning that big Fan 180° and let him suck like your vacuum cleaner?
That should be much more effectly.

Clever!
Using solder as a support while bending.Way to go Mike.
I just received the pump, man it is big! Alas, no time to start using it. I want to do this right.
But since the Nimble is now selling, I am running ragged designing additional adaptors left right and center.
But man oh man, what a good idea using the solder. My tubing is 2.9 and managed to get a 90 deg angle bent without problems, but did not want to start on the loop.
And of course, I then realised I need to start with the loop to make it fit the effector I designed for it.
I put that effector up on Thingiverse, in STL and STEP format so that it is easier to modify the model if anybody wants to.
