Re: [APD] Re: Heat exchanger - was aluminum in the aquarium

40 cfm at 11 db (a-weighted) is still terrific performance
for a small tube-axial fan. Some housed centrifugal blowers
can do that well at slow speeds, but that's incredible for
a tubeaxial fan! I'd expect a dbA rating about 3 times
larger from even a very expensive fan. Can you find out how
the measurement was made?
