What Are Custom Carbon Vanes?
Custom carbon vanes are precision-machined carbon or graphite sliding components manufactured to an approved application-specific specification rather than selected only from a standard catalog size.
Depending on the project, the material, dimensions, edge geometry, grooves, holes, profiles, orientation, marking, or packaging may be customized. Custom manufacturing still requires verification of the pump/compressor identification, rotor-slot information, material, speed, vacuum/pressure, and environment.
How Do Carbon Vanes Work?
- The rotor rotates eccentrically within the cylinder.
- Vanes move radially inside the rotor slots.
- Vane tips maintain the designed contact relationship with the running surface.
- Vanes divide the chamber into separate volumes.
- Chamber volume changes during rotation.
- Gas is moved to create vacuum or positive pressure depending on machine design.
Vanes perform sliding, sealing, chamber separation, radial movement, and wear compensation.
What Can Be Customized on a Carbon Vane?
Customization feasibility depends on material, vane size, geometry, tolerances, machining method, pump design, operating conditions, and quantity.

Where Are Custom Carbon Vanes Used?
Carbon and graphite vanes are commonly associated with many dry-running and oil-free rotary vane systems because suitable materials can provide dry sliding / self-lubricating behavior. However, not every rotary vane pump or compressor uses carbon vanes.
| Equipment Type | Carbon/Graphite May Apply? | Verification Needed |
|---|---|---|
| Dry rotary vane vacuum pump | Common direction | Pump + material |
| Oil-free rotary vane compressor | May apply | Compressor + grade |
| Vacuum/pressure combination | May apply | Both operating modes |
| Oil-lubricated rotary vane pump | Do not assume | Original material |
| Air motor | Do not assume | Separate design review |
| Screw / Claw pumps | No sliding vane | Not applicable |
Critical Rule: Dry-Running vs Oil-Lubricated
Original vane material and pump lubrication design must be verified before a custom carbon vane is specified.
- Dry / Oil-Free Systems: Carbon or graphite may be appropriate. Continue technical review of dimensions and operating parameters.
- Oil-Lubricated Systems: Oil-lubricated machines may use carbon composite, fiber composite, phenolic, polymer, metal, or other manufacturer-specific materials. Do not automatically assume carbon compatibility.
How Is Material Selected for a Custom Carbon Vane?
Carbon vane material should not be selected from dimensions alone.
Mechanical Factors
- • RPM & Rotor diameter
- • Vane length & Thickness
- • Rotor-slot fit
- • Pressure loading
- • Start/stop frequency
- • Vibration & Impact
- • Running surface condition
Thermal Factors
- • Pump operating temperature
- • Process-gas temperature
- • Compressor discharge temp
- • Thermal cycling
- • Cooling efficiency
Environmental Factors
- • Clean dry air vs Humidity
- • Moisture & Condensate
- • Dust & Abrasives
- • Oil mist exposure
- • Chemicals & Corrosive gases
Material Options & Verification
Broad material family and exact grade are separate decisions. CARBOLVE evaluates verified material options, including:
Note: Non-CARBOLVE comparison materials (like fiber composite, resin composite, metal, polymer) may exist in the market but are not assumed as CARBOLVE supply items unless verified.
Standard vs Custom
Standard: Existing specification, dimensions, and material. Starts from a catalog or part number.
Custom: Project-specific specification. Dimensions, material, and edge geometry can be modified where feasible. Starts from drawing/sample.
Custom does not automatically mean better. Use an existing approved product when it satisfies the application.
Custom vs Replacement
Replacement: Starts with an existing product with the goal to identify and replace it exactly. View Replacement Vanes.
Custom: Defines or modifies a specification.
Projects may overlap. An obsolete replacement project may become a custom project after a new CARBOLVE specification is approved.
OEM vs Custom Aftermarket
OEM: Original equipment manufacturer specification.
Custom Aftermarket: Manufactured by another supplier according to a separately verified specification.
Do not claim "exact equivalent" or "OEM approved" without verified evidence. Materials and testing routes differ.
Drawing-Based vs Sample-Based Manufacturing
| Information | Drawing | Physical Sample |
|---|---|---|
| Original dimensions | Usually available | Wear may alter dimensions |
| Tolerances | May be defined | Cannot always be inferred |
| Material | May be specified | May be unknown |
| Edge geometry | Defined | May be worn |
| Operating conditions | Separate data needed | Separate data needed |
The strongest project input is often a combination of drawing, sample, machine information, and operating data.
Custom Carbon Vane Specifications & Dimensions
Dimension Guide
Dimension terminology varies by pump manufacturer. Include an annotated sketch so CARBOLVE can confirm the measurement orientation.
- L = Length: Manufactured according to drawing or approved spec.
- H or W = Height / Width: Custom according to drawing or verified original specification.
- T = Thickness: Critical for rotor-slot fit.
Geometry & Features
Edge geometry may affect installation, running-in, contact, mechanical stress, and slot movement. Follow an approved drawing or verified original geometry rather than applying a generic edge design.
Required for Special Features:
For every custom chamfer, groove, hole, or profile, please request: Dimension, Position, Orientation, and Tolerance where required.
System Requirements for Custom Vanes
Rotor-Slot Fit
The vane must move freely in the rotor slot. Do not publish one universal clearance.
- Too tight: Sticking, heat, binding, breakage.
- Too loose: Tilting, impact, leakage, instability.
Request: Slot width, depth, rotor diameter, slot condition, operating temp.
Rotor Information
CARBOLVE manufactures vane components and does not manufacture the rotor unless verified. However, rotor data is critical for vane development.
Request: Rotor diameter, number of slots, slot angle, rotation direction, material, existing wear, deposits.
Cylinder / Stator Surface
"A custom carbon vane cannot compensate for a severely damaged rotor, slot, cylinder, or stator surface."
Check for: Scoring, scratches, grooves, deposits, pitting, corrosion, foreign particles, heat damage.
What Can Be Learned From a Carbon Vane Sample?
- • Length & Thickness
- • Remaining height
- • Basic profile
- • Edge geometry (if unworn)
- • Chamfer / Radius / Groove
- • Orientation markings
- • Wear pattern
- • Fracture pattern
What a Worn Sample May Not Reveal
A worn carbon vane is useful for reverse identification, but it is not always a complete engineering specification.
- Original Height: Often unknown once worn.
- Exact Material Grade: Cannot be reliably identified by color or appearance alone.
- Original Tolerances: Lost to wear.
- Original Edge: May be worn flat or chipped.
- Operating Limits: Maximum RPM, pressure, and OEM validation requirements are not visible on the part.
Custom Project Workflows
1. Custom Vanes From Your Drawing
2. Obsolete Vane Development
Obsolete does not automatically mean reproducible; sufficient technical information and suitable material must be available.
3. Dimensions-Only Project
Matching dimensions do not prove material or application compatibility.
Dimensions can be used to start a manufacturing review, but they may not be sufficient to establish the complete vane specification. We additionally request: Equipment, Pump model, Material, Edge geometry, Rotor slot, RPM, Vacuum/pressure, and Environment.
4. Changing Existing Material
Treat material substitution as an engineering change. We review: Why material is being changed, existing grade, failure mode, pump design, dry/lubricated, RPM, pressure, temp, dust, and rotor condition.
Finished-Vane Manufacturing & Quality Control
CARBOLVE’s finished-vane process focuses on precision machining and inspection of verified carbon and graphite materials.
Precision Machining
Control of Length, Height, Thickness, parallel faces, flatness, and squareness where verified. Final dimensional requirements should follow the approved drawing or verified application specification.
Edge & Feature Finishing
Machining chamfers, radii, bevels, grooves, holes, steps, and special profiles according to drawing. Proper edge geometry is critical for rotor-slot movement and sealing.
Quality Control
Inspection of material verification, dimensions (L, H, T), edge dimensions, flatness, surface condition (cracks, chips, scratches), and vane set consistency.
Custom Carbon Vane Applications
CNC Routing & Woodworking
Vacuum holding systems. Custom vanes often require evaluation of severe dust environments and filtration.
Packaging Machinery
Vacuum generation for applicable dry-running equipment requiring frequent start/stop duty cycles.
Printing Presses
Vacuum/air handling. Vanes customized for specific OEM pump models and combination pressure/vacuum duties.
Dry Compressors
Positive-pressure applications requiring material capable of handling specific discharge temperatures and pressures.
Custom Carbon Vane Troubleshooting
Vane problems can originate from the wider pump or compressor system. Changing material does not always solve a pump problem.
| Symptom | Possible Contributors | Check |
|---|---|---|
| Rapid wear | Material mismatch, dust, scored surface, excessive heat | Vane + operating environment |
| Broken vane | Sticking in slot, debris, impact, incorrect geometry | Rotor/slot condition |
| Vane sticking | Thickness out of tolerance, carbon dust buildup, moisture | Slot cleanliness & clearance |
| Vacuum loss | Worn vane, system leak, blocked filter, pump wear | Complete vacuum system |
| Excessive dust | Abnormal wear, external abrasion, rough cylinder surface | Filtration & cylinder surface |
