The 4500 Series cycle
With every rotation of the blower drive shaft, two lobe impellers turn in opposite directions transferring a constant volume of air or gas from inlet to discharge.
|
|
|
|
- Rated for continuous duty in all industrial applications.
- Provides longer life, simplified maintenance and reduced service intervals.
- Permits higher speeds and performance ratings.
|
|
|
|
- Compact, heavy-duty, and produced from high strength materials.
- Advanced case design with increased vent areas.
- The impeller case is precision machined from a single cast of high tensile iron and ribbed externally to prevent distortion.
- Ductile iron impellers equipped with one-piece alloy steel shafts.
- Equipped with bearings designed for heavy-duty applications and durability.
|
|
|
|
- Simple and precise timing gears maintain proper clearance between the impellers.
- Grip rings replace conventional timing hubs and guarantee the timing gears are mounted square and concentric to the shaft, resulting in minimum gear noise and wear.
- Located between the gear and the shaft, grip rings are sets of two complementary wedge section rings.
- Grips rings expand against the bore of the gear and contract on the shaft, ensuring an immovable friction fit.
|
|
|
|
- Elliptical shaped inlet port minimizes inrush air noise.
- An outlet port permits gradual release of downstream air and noise.
- These ports significantly reduce air noise, minimize mechanical loading, and control vibration.
|
|
|
|
- Timing gears and anti-friction bearings utilize abundant, dual-splash lubrication.
- Dual-splash lubrication eliminates the need for the customary pump, sump and vulnerable external tubing.
- Visual oil level indicators are located at both ends.
|
|
|
|
- Anti-friction bearings are locked against shoulders on both impeller shafts at gear end.
- These bearings maintain factory-set clearances between head-plates and impellers.
- Bearings are sized so the drive shaft may be direct or belt driven.
