Model 721 Sutorbilt 4500 Series Blower

Gardner Denver’s Sutorbilt 4500 Series Positive Displacement Blowers are large units rated for continuous duty in all industrial applications. They feature grip rings instead of conventional timing hubs that expand against the bore of the gear and contract on the shaft, ensuring the timing gears are mounted square for minimum wear and maintain their proper clearance.  These models can also be purchased with mechanical seals for gas service applications.
