?  Blowers deliver full pressure only at full speed.  Drop the RPM with 
reduced V and pressure drops exponentally.  IOW, the statement seems 
bogus, Skipp.  

Also, Alpha uses bypass/coupling type doorknob caps in tuned circuit 
applications.  I suppose that the designer did not read the Centralab 
catalog.
