Fuel Filter Blocking Tendency Tester

QualiFBT is an advanced fuel filter blocking tendency tester designed to evaluate the filterability of distillate fuels and biodiesel blends in accordance with ASTM D2068. By simulating the passage of fuel through a standardized filter membrane at a controlled flow rate, this instrument accurately measures the filter blocking tendency (FBT)—a critical indicator of contamination, stability, and suitability for engine performance.

Ideal for laboratories, refineries, and fuel quality control centers, the QualiFBT features a touchscreen interface, real-time data display, USB/LIMS connectivity, and automated safety features for precise, user-friendly operation.

Fuel Filter Blocking Tendency Tester Key Features and Benefits

  • ASTM D2068 Compliance: Measures filter blocking tendency using pressure and flow data during controlled filtration of sample fuel.
  • Automated & Precise Testing: Built-in computer and touchscreen control system ensure accurate results and minimize operator error.
  • Real-Time Data Monitoring: Displays temperature, pressure, volume, and method parameters throughout the test.
  • Over-Pressure Protection: Integrated pressure safety system for secure testing of fuel samples up to 105 kPa.
  • Flexible Fuel Compatibility: Suitable for fuels with kinematic viscosity between 1.3 mm²/s and 6.0 mm²/s at 40°C, including diesel, biodiesel, and biodiesel blends.
  • Data Management: Save, retrieve, and print test results through USB or connect to a LIMS for centralized data access.
  • Fast Throughput: Tests complete when either 300 mL passes through the filter or 105 kPa is reached, whichever occurs first.
