Note:
Example: Size 21 Performance air handler with airfoil damper mixing section, small coil section, medium access section, medium coil section, small
blank section, VFD control section, and fan section (down discharge) total unit length is 156.75 inches. Total roof curb weight for the 18-inch curb
would be 502.80 lbs (156.75 x 1.05 = 164.5875 lbs + 338.21 = 502.7975 lbs.)
