Additional Information

Additional Information

 N/A 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.

4500 Series Design Features

4500 Series Design Features

 N/A
  • Rated for continuous duty in all industrial applications.
  • Provides longer life, simplified maintenance and reduced service intervals.
  • Permits higher speeds and performance ratings.

Rugged Construction

Rugged Construction

 N/A
  • 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.

The 4500 Series Incorporates Simplified Timing

The 4500 Series Incorporates Simplified Timing

 N/A
  • 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.

Noise Reduction

Noise Reduction

 N/A
  • 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.

Lubrication

Lubrication

 N/A
  • 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.

Bearings

Bearings

 N/A
  • 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.
