N/A Assuming Motor/Drive Efficiency = 0.90 Cost/Kwh = $0.09

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.

Brake Horsepower Requirement Comparison chart shows a comparison of the BHP for a typical straight-lobe blower versus a CycloBlower® 9CDL23. The CycloBlower® requires less BHP to produce 3000 cfm at pressures from 8 to 20 psig.

Annual Energy Cost Savings chart translates the resulting BHP comparison reduction into annual energy cost savings. Calculations are based on the cost of providing 3000 cfm of air for 8736 hours, approximately 1 year, of operation assuming motor/drive efficiency = 0.90, and energy cost per kilowatt-hour = $0.09.

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.
