Many industrial fan applications require precise flows and pressures. Chamber testing in an AMCA-accredited laboratory verifies that the fan performs as cataloged (typically open inlet, ducted outlet). This eliminates the fan as a potential source of problems during commissioning or diagnostics, saving the end user time and money.
Air performance testing is one of the most common tests performed before any industrial fan deployment. Air performance testing precisely defines the fan’s performance characteristics including airflow rate, static pressure, horsepower, speed of rotation, and efficiency to ensure that the fan meets the required specifications for the application. Air performance tests should comply with AMCA 210 Laboratory Methods of Testing Fans for Certified Aerodynamic Performance Rating. This standard applies not only to the testing but also to the measurement chamber and reporting of results. In addition to documenting the test method and characteristics of the fan under test, the report contains the 10 equally spaced data points along the fan curve from near wide-open to near closed-off that were acquired during the test.
Air performance data is measured by laboratory-grade pressure transducers and rotary torque sensors of varying measurement ranges to accommodate the acquisition of differing maximum pressure and power values to be measured. Each
data point acquired represents an average of five seconds of data from at least 8 measurement signals and is redundantly verified within the test setup. At nyb laboratories, our capabilities include the ability to test fan air flow values up to
130,000 cubic feet per minute (CFM).
