The Air Movement and Control Association International, Inc. (AMCA) International approved AMCA 502-06 a new Damper Application Manual for
Heating, Ventilating, and Air Conditioning, and provides information and important points to be
considered when designing or specifying heating, ventilating, and air conditioning (HVAC) installations
requiring dampers for use in temperatures from -28 C to 121 C (-20 F to +250 F), pressures to 2500 Pa
(10 in. wg) and velocities to 25.4 m/s (5000 fpm).
AMCA 502-06 application manual is not intended to be used for detailed specifications; rather it serves as
a guide toward understanding the various types of dampers available and items to be considered for their
proper use. For dampers classified as fire dampers, radiation dampers and smoke dampers, see AMCA
