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.

Type
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 all air deflectors set perpendicular 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 1750 FPM for the 40° nozzles, 1000 FPM for the 90° nozzle and 1300
FPM for 5-way. For motor size, drive and blower rpm refer to pages 18 and 19. Mounting height measured from bottom of unit.
