In 1968, AMCA opened its testing laboratory in Arlington Heights, IL, U.S.A., a northwestern suburb of Chicago, about 25 minutes from O'Hare International Airport.
The laboratory is equipped to carry out tests in accordance with:
ANSI/AMCA Standard 210, Laboratory Methods of Testing Fans for Aerodynamic Performance Testing
AMCA Standard 220, Test Methods for Air Curtain Units
ANSI/AMCA Standard 240, Laboratory Method of Testing Positive Pressure Ventilators for Rating
AMCA Standard 300, Reverberant Room Method for Sound Testing of Fans
AMCA Standard 500-D, Laboratory Methods for Testing Dampers for Rating
AMCA Standard 500-L, Laboratory Methods for Testing Louvers for Rating
ANSI/AMCA Standard 610, Methods for Testing Airflow Measurement Stations for Rating
UL 555, Standard for Safety, Fire Dampers
UL 555S, Standard for Safety, Leakage Rated Dampers for Use in Smoke Control Systems
AMCA Standard 210
These facilities consist of three multiple nozzle chambers configured to test either fan inlet (Figure 15) or fan outlet (Figure 12) air performance as outlined in Standard 210. The two largest chambers can test up to 33 m^sup 3^/s (70,000 cfm) in the Figure 12 chamber and 42.5 m^sup 3^/s (90,000 cfm) in the Figure 15 chamber, at a maximum static pressure of 5500 Pa (22 in. wg.). AMCA's third chamber can test in either Figure 12 or Figure 15 configuration up to 9950 Pa (40 in. wg.). AMCA has tested fans with impeller diameters from 13 to 183 cm (5 to 72...
