Air Adjustment
In the event that reduced air volume is
required, an air volume band can be installed
within the blower wheel to reduce the
amount of air delivery. If the unit is factory
equipped with the air band but additional air
delivery is needed, the band can be removed
from the wheel.
The air band is sized according to the air
delivery specifications and can be ordered
from the factory for field installation.
The related photos of the wheel are provided
for practical guidelines only in order to
identify the air band location in the wheel.
Actual field installation of the air band into
the wheel will require access into and
through the blower wheel venturi.
The band is made of aluminum, sized and
equipped with easy bend tabs that are to be
inserted into pre-punched slots provided on
the wheel. Once the band has been inserted
into the slots, it MUST BE secured by
bending the tabs over from the back side of
the wheel and also MUST BE secured from
the inside by connecting the ends together
with a pop-rivet in the holes provided on the
ends of the band. If the band is to be field
installed, a hand held pop-rivet tool is
recommended for connecting the band ends
together. Caution must be taken to assure
that the band is tightly installed and no
damage, denting, or alteration to the wheel
or blades occurs during the installation.
