20.2.7 Characteristics of fan
(1) Cassetteria type (FDR)
● External static pressure table
How to interpret the blower characteristics table
Example : Case of FDRJ71HKXE2
1 2-spot blowout.....................
Internal resistance increases more
than the standard 3-spot blowout.
Approx. 14Pa(1.4mmAq) at
17m
3
/min
2 Square duct blowout...........
Internal resistance decreases more
than the standard round duct
(ø200 3-spot). 3Pa (0.3mmAq) at
17 m
3
/nin. (External static pres-
sure increases in reverse.)
3 Suction panel.......................
When the suction panel is not
used with the ceiling return type,
the part of internal resistance re-
lated to the panel decrease. 3Pa
(0.3mmAq) at 17mm
3
/min.

Unit : Pa (mmAq)
Notes (1) 1 spot closing: Round duct flange at center is removed and shield with a
special panel (option).
(2) Standard: Ø200 duct 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.
