Automotive Body Leak Tester

The Flow Dynamics Automotive Body Leakage Tester (BLT) is designed to perform static body air leakage tests on vehicles in assembly plants. This portable, self-contained unit enables automobile manufacturers to test their vehicle designs in accordance with recognized industry standards.

The BLT can determine the rate of air leakage into and out of a vehicle cabin under both pressure and vacuum conditions. Additionally, it can be used to test body components such as doors and windows with the use of custom adapters.


  • Calibrated against a primary standard air flow calibrator ensuring a consistent, high accuracy reading


  • Rate of flow is measured using a mass air flow sensor and displayed in Standard Cubic Feet per Minute (SCFM)
  • Differential pressure gage measures the difference in pressure between the vehicle cabin and the ambient environment


Flow Range
5…400 scfm
