I tried many fans (types and sizes) and found that squirrel cage fans worked best. Other fans created faster flow but produced much more noise. Ultimately the best types was like those found on HVAC air handler units.

For an "air play table" or a Bernoulli blower what would you suggest as a minimum air flow? CFM? I have used different fans in the past with different results. More often than not they were used squirrel cage fans that we had laying around and had a wide variety of outputs.  What I am looking for is some feedback from others about what they found worked best.
