Notes on
Performance Data.
•Performance data is
based on tests conducted
according to ANSI/
ASHRAE Standard
70-1991. Actual
performance in the field
may vary.
•Testing was conducted in
isothermal conditions.
•Sound levels are based
on a room absorption of
10 db re 10
-12
watts.
•A “- -” indicates a sound
level less than 20.
•A “ * “ indicates velocity
less than 10 fpm.
Units of Measure Used.
•Air flow is given in cubic
feet per minute (cfm).
•Pressure is given in
inches of water (w.g.)
•Velocity is given in feet
per minute (fpm).
•Sound levels are given in
both NC (Noise Criteria)
and RC (Room Criteria).
NC is the first with RC
second, separated by a
slash.
