Forced DraftHIGH EFFICIENCY AIRFOIL FANS

Design FeaturesInilially developed 30 years agofor packaged boiler syslems,Chicago's Packaged Forced Draftfan has earned a repulalion aslhe induslry slandard. The PFDis a compact, direcl connected,airfoil bladed fan offering excep-lional reliabilily. To afford lhehighesl efficiencies lhroughoullhe performance range, lhereare lhree wheel diamelersavailable for each fan size. Fanand wheel widlh can also bevaried lo oblain maximum per-formance. For syslems designversalilily, seven slandarddischarge posilions can bespecified in each rolalion.

ConstructionThe PFD is ruggedly con-slrucled wilh heavy gaugesleel housings suilably bracedfor high pressure. The enlireairslream seclion is conlinu-ously welded as is lhe wheel.The wheel hubis bushed lofacililale easiermounling. AIIfans arefurnishedslandard wilhflanged outlelsready forinstallalion.
