Fan Performance Using Accessory Power Exhaust
(551A155,180)
NOTE: The CRRFCURB013A00 high static regain adapter accessory may be
used to provide horizontal supply/return.
NOTE: The CRRFCURB013A00 horizontal supply/return adapter accessory
improves 551A155,180 fan performance by increasing external static pressure
by amount shown above. To convert from in. wg to Pa use the following formula:
in. wg x 249.1 = Pa
