Oil Cleaning Centrifuges
Spinner II® oil cleaning centrifuges use centrifugal force to remove particles, soot, and fine solids from lubricating and hydraulic oil without relying on filter media. Allied Reliability helps maintenance and reliability teams select, size, and support the right oil centrifuge for engines, hydraulics, gearboxes, and rotating equipment.
Centrifugal Oil Cleaning Built Around the Application
Spinner II oil cleaning centrifuges use centrifugal force to separate contaminants from oil without relying on disposable filter media. Installed in bypass or off-line configurations, each unit processes a controlled side stream and returns cleaner oil to the system without restricting main oil flow. T.F. Hudgins supports equipment review, model selection, sizing, retrofit planning, installation guidance, replacement parts, and long-term technical support.

Spinner II Product Models and Specifications
Model selection depends on sump or reservoir volume, oil viscosity and temperature, available pressure, target bypass flow rate, duty cycle, contamination load, available installation space, and service preferences. The table below is a starting point; final selection should be confirmed with a Spinner II application specialist.
| Product / Model | Flow Rate (GPM) | Rotor Type | Typical Use Cases |
| Model 25 | Up to .8 gpm (3 L/min) | Reusable rotor (placeholder) | Light-duty engines, small hydraulics (placeholder) |
| Model 996 | Up to 2 gpm (7.6 L/min) | Reusable rotor | Medium-duty fleets, off-road equipment |
| Model 200 | Up to 4 gpm (15.1 L/min) | Reusable rotor | Heavy-duty engines, high-soot duty cycles |
| Model 560/596HE | Up to 2 gpm (7.6 L/min) | Sealed disposable rotor | High-volume fleets, simplified servicing |
| Model 3600 | Up to 16 gpm (60.6 L/min) | Reusable rotor | Heavy-duty engines, high-soot duty cycles – off-road equipment |
| Parallel Systems | 100+ gpm (378+ L/min) | Consult factory | Custom applications |
THE CHALLENGE
Fine Oil Contamination Drives Wear, Cost, and Downtime
Oil contamination is a common reliability problem in engines, hydraulics, gear drives, and transmission systems. Ultra-fine solids can pass through conventional filtration, build up as soot or debris, and accelerate component wear before teams see obvious symptoms.
- Added handling requirements for waste oils, including waste motor oil in fleet applications
- Shorter oil drain intervals and frequent oil changes
- Higher maintenance cost from filter changes, oil disposal, and premature rebuilds
- Downtime risk from lubrication-related failures
- Inconsistent cleanliness across fleets, mobile equipment, and plant assets
HOW IT WORKS
How Spinner II Centrifuges Improve Oil Cleanliness
Spinner II oil cleaning centrifuges separate contaminants by spinning oil at high RPM, generating thousands of times the force of gravity. Fine solids are driven out of suspension and packed into a dense cake on the bowl wall, helping remove particles that contribute to wear and oil degradation. Properly sized systems support longer service intervals, more stable oil cleanliness, and better protection for high-load or high-contamination assets.
Remove Fine Solids
Capture soot, wear debris, dust, and other particles that contribute to lubricant degradation and component wear.
Support Longer Service Intervals
Help maintain oil condition so maintenance teams can use oil analysis and operating data to make more informed drain and service decisions.
Reduce Consumable Waste
Reusable-rotor models avoid disposable filter elements; sealed-rotor options simplify handling where that maintenance model is preferred.
Protect High-Load Assets
Apply centrifugal oil cleaning to engines, hydraulic systems, gearboxes, turbines, compressors, pumps, paper machines, fans, blowers, circulating oil systems, and crushers.
