NOTES:
1. Table 1 based on up to 4-foot grille length. For longer lengths, correct
throw and NC per Table 2.
2. When using continuous grille lengths with alternate active and inactive
sections, a reduction in throw can be obtained by omitting the factors
contained in Table 2.
3. Bar style 30 and 0
Increase Table 1 NC + 5 NC
4. Supply air temperature effect on horizontal throw is shown in Table 3. verti-
cal down-throw at varying supply temperatures is shown in Table 4.
5. When spreading the air path with a horizontal deflection of 22º per side in
grille lengths up to 4 feet:
Multiply Table 1 Throw x .75
Increase Table 1 NC + 5 NC
Multiply Table 1 P

x 1.20
Multiply Table 5 A

6. Terminal velocities (V
t
) at the minimum and maximum throw (T) values
are rated at 125 FPM and 75 FPM respectively with corresponding room
velocities (V
r
) of 50 FPM and 35 FPM.
