Pressure Drop
Pressure drop data is provided for various damper sizes and airflow velocities, illustrated in AMCA Figures 5.2, 5.3, and 5.5. These figures detail pressure drop in inches of water gauge (in. wg) for different velocities in feet per minute (fpm).
Space Envelopes
Externally mounted actuators require space outside the damper sleeve. The 'S' dimension indicates the clearance needed for various actuators. The table below shows worst-case space envelopes for different actuator types/models, including the FSAFB24 SR(-S) Belimo.
| Actuator Type/Model | B* (With RRL, RRL/OCI, or TOR) | T* (With RRL, RRL/OCI, or TOR) | S (PiggyBack) |
|---|---|---|---|
| FSAFB24 SR(-S) Belimo | 1½ in. (38 mm) | 9¼ in. (235mm) | 6 in. (152mm) |
* For dampers 18 in. (457mm) or more in height, these dimensions are 0 in.
Contained Actuator Option
This option allows the actuator to be oriented so it extends no more than 1½ inches above or below the sleeve. For dampers 11 inches high or less, the RRL, RRL/OCI, or TOR may be mounted on the side opposite the actuator.
Sleeve and Sideplate Dimensions
The diagrams and table illustrate the position of the FSD-211M damper within a factory sleeve, showing the 'A' dimension for mounting actuators, controls, and allowing space for retaining angles and duct connections. The standard 'A' dimension is 7 3/16 in. (183mm), with a range from 7 3/16 in. (183mm) to 16 in. (406mm).
Note: The entire damper frame does not need to be within the wall; however, the damper blades, when closed, must be contained within the wall.
Transitioned Damper Dimensions
The FSD-211M can be supplied with round or oval transitions on factory sleeves for use with corresponding ductwork. The drawings show overall damper sizes for Type R (round), Type O (oval), and Type C (custom) transitions.
*These dimensions are furnished approximately 1/4 in. (6mm) undersize, except round and oval dimensions which are approximately 1/8 in. (3mm) undersize. Ts = (2)(Sleeve Thickness).
Multiple Section Dampers
Dampers exceeding the maximum single section size are provided as factory assemblies of two or more equal sections. The figures show maximum damper section size and assembly configurations for multi-section dampers, including two sections wide (72 in. wide x 36 in. high) and two sections high (36 in. wide x 72 in. high).
