Basic Components
Housing body: the main structure containing the inlet/outlet port, generally made of aluminum alloy, plastic or stainless steel
Filter element connection: Spin-on or Cartridge
O-ring: Ensure the filter element and housing are sealed to prevent leakage
Inlet/outlet port: standard threaded or quick plug interface, connecting to fuel pipeline
Water Bowl: Installed at the bottom for collecting moisture with drain valve
Water level sensor interface: detects whether there is any water accumulation
Manual pump (hand oil pump): used for manual exhaust or pre-oil supply
Heater interface (optional): Preheat diesel in cold climates to prevent wax from precipitating out and blocking the filter element
Specifications
1.Suitable fuel: diesel, gasoline, biodiesel (B5/B20/B100), kerosene, etc.
2.Housing material: aluminum alloy (died casting), plastic (nylon PA66+GF), stainless steel 304/316.
Working pressure: generally 0.3–1.5 MPa (3–15 bar), common rail system may be higher (up to 3 MPa).
Temperature range: -40°C ~ +120°C (high temperature type with heater up to 150°C).
Filtration accuracy: 2μm, 5μm, 10μm, 20μm (depending on the filter element).
Interface specifications: M14×1.5, M16×1.5, 3/8"-18 NPT, quick plug Ø8/Ø10/Ø12.
Filter element compatibility: Spin-on, Cartridge.
Water cup capacity: 50–150 ml with drainage knob or electronic water sensor.
Filter size: Height 70–200 mm, diameter 60–120 mm (depending on vehicle model or equipment).
Installation method: flange, bracket, screw fixation, horizontal or vertical installation.
Application Scenarios
Passenger car gasoline/diesel filtration system
Commercial vehicle (truck, bus, heavy truck) diesel system
Construction machinery (excavator, loader)
Diesel generator set
Ship/Maritime Engine
Agricultural machinery and equipment (tractors, harvesters, etc.)
Select Suggestions
Fuel type: If biodiesel (B20/B100) is used, the corrosion resistance of sealing rings and plastic parts must be confirmed.
High filtration accuracy requirements: Rail system recommended to choose ≤5μm accuracy, with moisture separator.
Ambient low temperature operation: live heating function should be selected, combined with heater controller.
Frequent maintenance occasions: It is recommended to choose a transparent water cup + hand pump + quick-install filter element structure.
Flow demand: General passenger car: <100 L/h, engineering vehicle/generator: 100–500 L/h or higher.
Automatic monitoring requirements: can be connected to water level sensor and pressure differential sensor, equipped with CAN or PLC communication module.
