Duct Blaster®

  • A lightweight Duct Blaster fan weighs just 7 pounds, but delivers enough air flow (an amazing 1,500 CFM) to test even the leakiest of duct systems
  • Quick and accurate air tightness measurements from 20 - 1,500 CFM. Compatible for both pressurization and depressurization testing. Compatible for both pressurization and depressurization testing.
  • The Duct Blaster can be easily used in new construction applications where a Blower Door can't be used (e.g. before sheet rock is installed).
  • The Duct Blaster can also be used as a powered flow hood to accurately measure air flows through the air handler fan, registers and grilles, and exhaust fans.
  • It incorporates a variable fan speed control (solid state) available for both 110V and 220V models and a data collection module for communication with and control by the laptop.
  • Includes a padded nylon carrying case with shoulder strap.

TrueFlow® Air Handler Flow Meter


  • Designed to provide a simple and accurate measurement of airflow through residential air handlers.
  • The TrueFlow Meter temporarily replaces the filter in the air handler distribution system during the airflow measurement process.
  • If the filter location is directly adjacent to the air handler, the TrueFlow Meter will measure the total air handler flow.
  • If the filter is located remotely at a central return, the TrueFlow Meter will measure airflow through the central return.
