How to interpret the blower characteristics table
Example : Case of FDR308-A
1 2-spot blowout.....................
Internal resistance increases more
than the standard 3-spot blowout.
Approx. 14 (1.4) Pa (mmAq) at
17m
3
/min.
2 Square duct blowout...........
Internal resistance decreases
more than the standard round
duct (ø200 3-spot). 3 (0.3) Pa
(mmAq) at 17 m
3
/nin. (External
static pressure increases in
reverse.).
3 Decorative panel...................
When the decorative panel is not
used with the ceiling return type,
the part of internal resistance
related to the panel decrease. 3
(0.3) Pa (mmAq) at 17mm
3
/min.

Notes (1) 1 spot closing: Round duct flange at center is removed and shield
with a decorative panel (option).
(2) Standard: ø200 ducts are installed at all blowout holes.
(3) Square duct: All round ducts are removed and replaced with special
square duct flanges (option).
(4) When operating at a high speed, invert the connection of white
and red connectors on the flank of control box.
