Ola!  I'm Miguel de Mattos from Lisbon, Portugal.

I have a 65 Themodist Steck piano, and I would like to put a suction
set on it.  But normally these kind of suction pumps [turbines] are
a bit noisy.

I would like to build an air bellows pump like those which are used in
reproducing player pianos.  Can anybody tell me how this kind of pump
works inside?

Best wishes

Miguel de Mattos
