Chicago Blower’s wheels feature air-
foil blades continuously welded to a
streamlinedwheel cone and heavy
steel backplate. The hollow blades
have weep holes to prevent mois-

Airfoil wheels have true non-over-
loading horsepower characteristics,
mechanical efficiency over 80% and
a steep stable pressure curve, ideal
for applications with pressure varia-
