Nozzles - Performance
A choice of four air discharge
nozzles accommodate various
heat throw patterns illustrated.
Equipped with adjustable louver
blades, nozzles are fabricated
from galvanized steel and are
offered either unpainted or
painted to match the finish of the
blower unit heaters. Nozzles are
flanged for easy attachment over
the air discharge opening of the
blower unit heater.

The above table is based on an inlet air temperature of 70°F and an air temperature rise of 55°F.Air deflectors on 40° and 90° discharge nozzles set perpendicular to the
face of the air discharge opening.On 5-way nozzles, bottom air deflectors set perpendicular to floor, all other deflectors at 30° to floor.Static pressure measured at 0.1 W.
C.for 90° nozzle 0.2 W. C. for 40° downward and 5-way nozzle and 0.3 W.C. for 40° splitter nozzle.Outlet velocities are approximately 1850 fpm for the 40° nozzle, 900
fpm for the 90° nozzle and 900 fpm for 5-way nozzle.For motor size, drive and blower rpm refer to pages 10 and 11. Mounting Height measured from bottom of unit.
