Commercial HVAC fan systems have a new testing capability in the United States.
Q-PAC's airflow laboratory in Elkton, Florida, has become the first laboratory accredited by AMCA International specifically for fan-array testing under ANSI/AMCA Standard 270, alongside AMCA 210/ASHRAE 51 testing capabilities.
The facility can test airflow from approximately 2,000 to 70,000 CFM and accommodate both individual fans and larger fan-array configurations.
That matters because fan arrays increasingly appear in large air handlers and commercial HVAC systems where multiple fans operate together.
Testing individual fans does not always replicate how several fans behave once they are installed as a system.
AMCA 270 provides a standardized method for evaluating the aerodynamic performance of the complete fan array.
Q-PAC says the facility can measure airflow, pressure, fan speed, input power, temperature and other operating conditions while testing different fan quantities and control strategies.
For OEMs and engineers, the significance is practical.
More representative testing can reduce reliance on extrapolated performance assumptions when designing large air-handling systems.
For contractors and building owners, better validated fan-array performance can eventually translate into more accurate equipment selection, commissioning expectations and energy calculations.
It is a technical development rather than a major acquisition or regulatory change, but it addresses an increasingly important part of commercial HVAC: proving how equipment performs as an integrated system rather than simply rating individual components.
