Air Pump That Intakes Through A Tube And Pushes Air Out Of A Tube?

[SimonSays]

I'm looking for an air pump that sucks air in through a specific tube and out a specific tube

All the air pumps I see seem to intake air from the unit itself and shoots air out through a tube.

I need something like...

tube - unit - tube


any ideas? thanks!

You could acheive that with a regular airpump. Put it in a sealed box with holes in it for the cable, inlet and outlet pipes, (sealant to keep the box airtight). The pump is still pumping air from it's surroundings, but the only way air can get into the box is through the inlet tube.

Obvious question is "why" ? I seem to remember piston pumps do as you ask - if they are still available...

This thread springs to mind. Piston pumps were all we had when I started, they were great, really quiet, with the added advantage of watching the flywheel go round.
