Oil Cleaning Centrifuges For Transit Service
Spinner II oil cleaning centrifuges help public transit fleets remove soot and fine particulate, extend lube oil service intervals, and reduce oil-related maintenance costs.
For diesel and CNG engines, Spinner II works alongside the full-flow oil filter to keep oil cleaner, protect critical components, and keep vehicles in service longer.


Cleaner Oil for Transit Fleets That Depend on Vehicle Availability
Transit fleets operate on fixed routes, public schedules, and demanding maintenance windows. Diesel and CNG engines must stay available while maintenance teams manage soot, fine particulate, oil service intervals, filter changes, labor requirements, and component wear across many vehicles.
Spinner II provides high-efficiency bypass filtration that removes both larger contaminants and ultra-fine particles from engine oil, helping fleets reduce oil-related maintenance and protect engines over extended service intervals.
Operating CHALLENGES
Transit Maintenance Teams Need Control Over Soot, Wear, and Service Time
Oil contamination can quietly increase cost across an entire fleet, especially when service intervals, oil purchases, filter changes, labor hours, and engine wear are multiplied by every truck in operation.
- Soot loads generated by modern low-emissions engines
- Waste oil and filter disposal costs
- Fine particles that contribute to engine and turbocharger wear
- Oil and filter changes that consume labor and reduce truck availability
- Inconsistent oil cleanliness across the full service interval
- Difficulty validating extended drain decisions without oil analysis and cost data

HOW SPINNER II HELPS
High-Performance Bypass Oil Cleaning for Diesel Engines
Spinner II centrifuges are installed in addition to the full-flow oil filter. The centrifuge removes contaminants from the oil stream rather than relying only on media filtration, helping maintain constant cleaning efficiency across the service interval.
Spinner II centrifuges remove particles as small as one-tenth of a micron, offer up to 10 times the debris-holding capacity of high-performing filters, and use a convenient disposable rotor for routine service.
Transit Fleet Benefits That Support Route Availability
Cleaner oil helps transit maintenance teams reduce oil-related service demands while supporting longer engine and component life.
- Efficiently remove soot and fine particulate from engine oil
- Decrease oil-related maintenance so vehicles can remain in service longer
- Reduce critical component wear and help protect engines
- Use high-capacity rotors to store debris over extended service intervals
- Extend the life of oil and filters when supported by proper validation
- Simplify routine service with convenient rotor handling.
