Filtration Categories Supplied
Complete Multi-System Filtration for Cummins Powerplants
Cummins engines demand filtration designed to handle extreme thermal cycling, heavy soot dispersion, and moisture in bulk fuel storage tanks. We provide OEM equivalent aftermarket filters, matched across every system.
Engine Lube Systems
Patented Venturi combo design integrating full-flow stacked disc media with a high-density bypass section; captures abrasive soot down to 10 microns without cold-start pressure bypass to preserve bearings.
Fuel & HPCR Water Separation
StrataPore® and multi-layer micro-glass media removing 99%+ free and emulsified water; secondary 2–5 micron filters engineered to protect PT fuel pumps, HPI-TP, and high-pressure common rail injectors.
Heavy-Duty Air Intake
Direct-fit primary radial seal elements, safety inner elements, and OptiAir™ / Magnum RS™ systems delivering maximum CFM airflow while arresting abrasive silica dust in quarry canopies and plant rooms.
Coolant & Liner Cavitation Protection
Chemically balanced spin-on water filters pre-charged with DCA4 (Dry Chemical Additive) pellets to maintain coolant chemistry, prevent cylinder liner cavitation pitting, and eliminate radiator scale.
Crankcase Ventilation (CCV) & Gas Elements
Open and closed crankcase ventilation (CCV) coalescing filters to capture oil blow-by mist before it fouls turbochargers or exhaust stacks, plus gas-fuel particulate scrubbers for GTA sets.
Preventive Maintenance Kits
Standardized “B-Check” & “C-Check” Cummins Service Bundles
Never let an unpredicted failure take your facility off the grid. Consolidate your maintenance procurement into vehicle-matched, single-shipment filter kits packaged for scheduled servicing.
Routine B-Check / 250–500 Hour Service Kit
Contents: Full-flow engine lube filter (or combo element), primary fuel water separator element, and secondary fuel filter.
Application: Standard scheduled periodic servicing for 4BT, 6BT, 6CTA, and B-series/C-series 25 kVA – 250 kVA generators.
Comprehensive 500-Hour PM Kit (Heavy Duty)
Contents: Lube combo filter (LF9009), secondary fuel element, primary water separator (FS1000/FS1212), outer radial air filter, and DCA4 chemically charged coolant filter (WF2075).
Application: Standard scheduled PM cycle across NTA855, QSL9, and KTA19 engines.
Comprehensive C-Check / 1000–1500 Hour Overhaul Kit
Contents: Complete 500-Hour engine pack + inner air safety filter, crankcase ventilation (CCV) coalescer element, bypass centrifuge rotor/liner, and fuel tank breather cartridge.
Application: Major mid-life overhaul for continuous 24/7 manufacturing plants, mines, and hospital critical power units.
High-Horsepower Multi-Megawatt Plant Kit (KTA38 / KTA50 / QSK60)

Frequently Asked Questions
Why is Fleetguard the factory standard for Cummins engines and CPG generators?
Fleetguard is Cummins Filtration—the filters are co-engineered with the engines. Fleetguard’s patented StrataPore® and NanoNet® media deliver the precise flow characteristics, burst ratings, and micron thresholds required to uphold Cummins factory engine standards and ensure warranty compliance.
What is the difference between a standard lube filter and a Fleetguard Venturi Combo filter (like LF9009)?
A standard full-flow filter passes oil through paper media to capture larger wear particles (30–40 microns). The Fleetguard Venturi Combo filter integrates a full-flow section with an internal bypass section that pulls a portion of the oil through dense synthetic media to strip soot and ultra-fine particles (down to 10 microns) without causing pressure drops across the lubrication circuit.
How do I calculate the correct DCA4 coolant filter (WF series) for my Cummins engine?
Coolant filters contain specific DCA4 units (chemical charge) calculated based on total cooling system capacity (gallons/liters). Installing the wrong unit can either under-treat (leading to cylinder liner pitting) or over-treat (causing water pump seal leakage). Share your engine model or cooling capacity, and we calculate the exact WF part number required.
Can you cross-reference original Cummins equipment part numbers to Baldwin or Donaldson?
Yes. If you prefer to standardize your multi-brand fleet on Donaldson or Baldwin, we cross-reference your Cummins or Fleetguard numbers directly to validated Tier-1 alternatives that maintain identical factory fit and micron ratings.
