€ Kooltronics®, in Ventura, CA, makes two, types of blowers for 
high-pressure applications: radial-wheel, and large diameter/narrower 
wheel squirrel-cage types.   The pressure ability of the radial-wheel 
type is up to six (6) inches of water column, which is roughly double the 
ld/nw type.  However, the trade-off is that radial-wheel =s less volume.  
-  Unlike consumer-product blower manufacturers, Kooltronics uses 
high-efficiency capacitor-run motors that run cool to the touch.  Also, 
all moving parts are electronically-balanced to reduce vibration.  
However, 'mo betta costs 'mo $$.
