''Quite a bit'' is not much help.   I need a measurement.  //  I am going 
after the statement of ''over 250 cfm...''.  Just because the blower 
manufacturer says congratulations, you have purchased a 250cfm blower 
does not mean that it will actually do 250.  .  Eimac says that at sea 
level, it takes 0.6" of pressure to flow 34cfm in a 4CX1500B.  My guess 
is that to put 250cfm through a pair of 1500B coolers, it would take a 
Force-4 hurricane.
