AMCA Air Flow Tunnel

Airflow Sciences Corporation has introduced the Air Flow Measurement Tunnel, a self-contained measurement system meeting ANSI/AMCA specifications and 2% accuracy to measure system air flow rates from 10 to 500 CFM.

The Air Flow Tunnel allows for the generation of fan and blower performance curves as well as pressure drop curves in order to measure and improve flow resistance within ductwork, radiators and other system components.

Airflow Sciences Air Flow Tunnel ASC manufactures air flow tunnels to customer specifications, shown below:

  • Model AFT-1500 (10 to 1500 CFM)
  • Model AFT- 500 (10 to 500 CFM)
  • Model AFT-100 (5 to 100 CFM)
  • Model AFT- 8 (.1 to 8 CFM)

Software / Data Logger

PC based software performs data logging for all flow tunnel components (fan, transducers, temperature), ambient conditions (pressure, temperature, humidity) and Unit Under Test (UUT) operating conditions (fan voltage, RPM, actuator motor voltage). Software features user input of test conditions and selection of nozzle. On-screen display of results during testing. Exports data for Excel spreadsheet import.

Performance and Operation

As air is moved through the chamber the pressure drop is measured across the nozzle plane. Expected accuracy is +/-2% of full scale for each nozzle, and typical accuracy of calibration results are better than 1% of the reading.
