The "bouncer" inflatable bags seem unrelated to pipe organs which
need flowing air at constant pressure.  John Adams purchased a type
CF-195 24-volt surplus blower suggested by Andy LaTorre and tested
it with an organ; his conclusion was "save your money!"  See

I'd like to hear from MMD readers who have actually tested a surplus
blower with a pipe organ and judged it satisfactory and would recommend
it to others.  Used small Orgoblo units are hard to find nowadays...
