AMCA standardizes induced flow fan rating

摘要

Air Movement and Control Assn. International Inc. (AMCA) Standard 260-07 "Laboratory Methods of Testing Induced Flow Fans for Rating" establishes a uniform method of laboratory testing for fans. The standard determines the aerodynamic performance in terms of inlet and outlet airflow rate, pressure developed, power consumption, air density, speed of rotation, and efficiency. This standard supports ANSI/AMCA Standard 210-99, "Laboratory Methods of Testing Fans for Aerodynamic Performance Rating" to accommodate the induced flow fan's unique characteristics. To ensure that a specified induced flow fan will have the expected performance, engineers should include language that the fan is tested in accordance with AMCA 260-07.
