1 2-spot blowout.....................
Internal resistance increases more than
the standard 3-spot blowout. Approx.
14Pa (1.4mmAq) at 17m
2 Square duct blowout...........
Internal resistance decreases more than
the standard round duct (ø200 3-spot).
3Pa (0.3mmAq) at 17 m
(External static pressure increases in
reverse.)
