The single bag diesel filter housing is a critical component in industrial and high-flow diesel filtration systems. It is primarily designed to protect key equipment such as diesel engines, fuel boilers, and generator sets from particulate contamination, ensuring reliable operation and extended service life.

Unlike the spin-on filter assemblies used in vehicles, single bag housings are deployed in fixed or large mobile equipment for fuel pre-treatment and polishing filtration:
Diesel Power Generators: Serves as a pre-filter ahead of the engine's fine filters, significantly extending the life of expensive final-stage filter cartridges.
Fuel Boilers/Burners: Ensures clean diesel supply to burners, preventing nozzle clogging and maintaining optimal combustion efficiency.
Marine Diesel Engines: Used in ship fuel systems to filter diesel from storage tanks before it reaches the engines.
Heavy Equipment & Fleet Management: Employed in refueling trucks or fixed fueling stations to ensure clean fuel is dispensed into vehicle or equipment tanks.
Diesel Storage & Transfer Systems: Installed at tank farm outlets or within pipelines to purify diesel, removing contaminants like rust, scale, or microbes from storage before it enters downstream equipment.
Industrial Machinery (e.g., compressors, pump stations): Any industrial equipment powered by diesel requires clean fuel for reliable operation, making these housings essential.
High Dirt-Holding Capacity: A single large filter bag provides extended service cycles.
Robust Industrial Design: Built to withstand the demands of continuous industrial operation.
Cost-Effective Maintenance: Simple bag change-out reduces downtime and operational costs.
Versatile Configuration: Available in various materials (e.g., carbon steel with lining, stainless steel) and pressure ratings to suit specific fuel handling requirements.
| DN | Typical Flow Range (m³/h) | Typical Filter Area (㎡) | Key Applications |
|---|---|---|---|
| DN25 | 2 - 10 | 0.1 - 0.25 | Precision fuel filtration for stand-alone equipment: mid-sized diesel generators, fuel oil burners, small test stands, and mobile pumping units. |
| DN40 | 10 - 25 | 0.25 - 0.5 | Standard industrial unit: core filter for large single gensets (500kW+), small marine mains, medium industrial burners, and small fleet refueling points. |
| DN50 | 20 - 40 | 0.5 - 1.0 | Primary filtration for heavy-duty applications: MW-class gensets, large marine auxiliaries, central fuel stations for medium equipment clusters (2-3 units), and critical systems requiring long service intervals. |
| DN65 | 30 - 60+ | 0.7 - 1.5+ | System-level core / high-flow processing: Main fuel systems for power plants/large plants, outlet of large marine day tanks, bulk loading at depots, terminal filtration for biodiesel or heavy fuel oils. |
