Damper Application Manual for Heating, Ventilating, and Air Conditioning
The purpose of this publication is to provide 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). It is not the intent of this manual 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 Publication 503.
