 N/A CycloBlower® Gardner Denver™

Efficient, Shock-Free Compression

Efficient, Shock-Free Compression

 N/A
  • Helical screw rotors generate a balanced compression cycle.
  • Providing a smooth and steady discharge, eliminating the sudden release of trapped pockets of air into the line.
  • Contoured inlet and discharge ports minimize turbulence.

Dependable Quality

Dependable Quality

 N/A
  • Superior and consistent quality can be found in every CycloBlower® as a result of:
    • Continual investment in the training of world-class manufacturing personnel.
    • Quality inspections throughout the entire manufacturing process.
  • Compact design utilizing optimum performance materials.
  • Reduced vibrations result in longer service of critical blower components.

High Capacity

High Capacity

 N/A
  • Industry unique rotor profile and accurately maintained tolerances allow the CycloBlower® to be operated at high speeds for increased capacity.

Clean Air/Gas Delivery

Clean Air/Gas Delivery

 N/A
  • Contact-less rotors removes the need for lubrication within the compression chamber.
  • Outboard position of rotor bearings allows atmospheric venting between the compression chamber and the bearings and gears.
  • Prevents gear and bearing lubricants from contaminating the compression chamber for clean air/gas delivery.

Installation Flexibility

Installation Flexibility

 N/A
  • Units can be powered by various types of drives including electric motors, constant or variable, gasoline and diesel engines, or steam turbines.
  • May be connected through a variable frequency drive (VFD), V-belt, or direct drive.

Low Installation Cost

Low Installation Cost

 N/A
  • A special foundation is not required.
  • CycloBlower® requires a minimum of floor space.
  • Remanufactured units available.

High Efficiency for Improved Energy Savings

High Efficiency for Improved Energy Savings

 N/A In many comparable applications, the CycloBlower® operates more efficiently than other straight-lobe blowers. By requiring less brake horsepower, BHP, energy operating costs can be realized and reduced.

Unique CycloBlower® Design Features

Optimum Efficiency, Proven Results

 N/A The CycloBlower® stands out as the premium PD blower/vacuum pump in the market. The meshing of two helical lobe rotors synchronized by timing gears provides controlled compression of air for unmatched efficiency and shock-free discharge. State-of-the-art manufacturing techniques, improved assembly methods, and enhanced internal clearances allow the CycloBlower® to operate at higher operating speeds for increased flow capacities. For optimal performance, we recommend AEON® PD and AEON® PD-XD (Extreme Duty for high ambient and/or high discharge temperatures) lubricants.

Rotors

 N/A Helical four-flute gate rotor and two-lobe main rotor are milled from high tensile strength ductile iron, stress relieved and dynamically balanced.

Housing

 N/A One piece, high strength housing resists deflection to retain accurate running tolerances between rotors. Contoured porting provides smooth airflow.

Bearings

 N/A Anti-friction bearings carry the shaft loads in all models. CycloBlowers use pairs of angular contact ball bearings on the discharge end and cylindrical roller bearings or single-row ball bearings on the gear end.

Timing Gears

 N/A Synchronization of rotors is through a pair of helical timing gears. Precision alloy steel gears provide quiet, accurate operation.

Air/Gas Seals

 N/A Labyrinth-type shaft seals provide a minimum of controlled leakage of air or gas. Purged labyrinth seals or mechanical seals are available with units handling gas, where leakage cannot be tolerated.

Dual-Splash Lubrication

 N/A Gears and bearings are lubricated by a splash oil system.

Oil Seals

 N/A All CycloBlowers are fitted with proprietary bearing isolator seals. Our unique design developed in partnership with Inpro/Seal offers outstanding performance and longevity.
