FanTestic – Manual Test

Learn how to input data into FanTestic software from a manual blower door test. Also, get tips and information on best practices. https://youtu.be/vn1z8VFBBj8

Start a New Manual Test

  • Open File → New test and select your protocol (e.g., ASTM, ATTMA, EN13829).

  • Verify test standard in Tools → Options, as it sets the calculation framework for later steps

Enter Fan and Gauge Calibration

  • Choose your fan model and serial number; click the wrench icon to input calibration coefficients (N & K values).

  • Do the same for your gauge—select its serial, add range-specific correction factors.

Input Building and Environmental Data

  • Fill in envelope area, floor area, and building height above ground.

  • Enter environmental factors: baseline (bias) pressure, temperatures, barometric pressure, wind speed/direction, and operator location

Enter Test Readings

  • In the Data Sets section, choose Enter Data Manually = Yes to unlock input fields.

  • For each pressure point:

    • Stabilize the system (20–40 s averaging recommended when windy).

    • Use gauge HOLD to freeze readings for recording.

    • Input induced pressure (Pa) and corresponding airflow (CFM).

  • Add baseline/final bias readings before and after test points

Complete and Calculate

  • Once all fields are green, click Calculate. FanTestic will generate leakage curves, ACH50, ELA, and report deviations from standard compliance.

  • You can run multiple Data Sets—like pressurization + depressurization—or compare pre- and post-seal results

Save and Export Reports

  • Save your test file via File → Save As.

  • Generate Word reports or export raw data to Excel for further analysis

Best Practices

  • Time Averaging: Use at least 20 s for pressure/flow readings and 5 s for baseline/bias readings when manually entering data.

  • Gauge HOLD: Always freeze the readings before logging data to ensure accuracy.

  • Accurate Calibration: Enter fan and gauge corrections early to ensure flow is computed correctly.

  • Multiple Sets: Capture test points in both pressurization and depressurization for balanced results.
