Air Movement and Control Association (AMCA)

The centrifugal fan achievement tables accommodate the fan RPM and ability requirements for the accustomed CFM and changeless burden at accepted air density. When the centrifugal fan achievement is not at accepted conditions, the achievement charge be adapted to accepted altitude afore entering the achievement tables. Centrifugal admirers rated by the Air Movement and Control Association (AMCA) are activated in laboratories with analysis setups that simulate installations that are archetypal for that blazon of fan. Usually they are activated and rated as one of four accepted accession types as appointed in AMCA Accepted 210.3

AMCA Accepted 210 defines compatible methods for administering class tests on housed admirers to actuate airflow rate, pressure, ability and efficiency, at a accustomed acceleration of rotation. The purpose of AMCA Accepted 210 is to ascertain exact procedures and altitude of fan testing so that ratings provided by assorted manufacturers are on the aforementioned base and may be compared. For this reason, admirers charge be rated in SCFM
