MODEL #5200-P
The blower and slidegate controls
working together
affect the distance fiber can be blown through a hose without
plugging. These controls also affect the accurate blowing of
fibers for spraying applications.
These settings control the following:
•
Density
of fiber blown in application.
•
Velocity
of material impact when spraying.
•
Dust
on open blow.
• Material
spread rate
or coverage.
•
Production
rate (lbs. per hour blown).
General Blower Control and Slidegate Settings for Open Blow:
With the
slidegate
closed and blower control valve on low (valve open), turn
agitator-feed and
blower on
. Fill hopper with insulation and adjust
blower valve
and
slidegate.
Move controls
proportional to each other. (i.e. If
blower valve
is half open,
slidegate
should be half open.) As hose
length is increased, air pressure/volume is increased by closing off the
blower valve
while closing the
slidegate proportionally. This will increase the distance fiber can be blown through the hose, while
decreasing the blowing production rate (lbs. per hour blown). (See illustration 7)
Shredder Assembly:
This unit is supplied with a shredder assembly; airlock/agitator speeds are preset at the factory.
No
further sprocket setting speeds are needed, as this system will accommodate most fibers and
applications. However, the shredder and agitator
direction
can be adjusted as described below.
Shredder & Agitator Adjustment:

Unidirectional Rotation
(See illustration 8) is preferred as an all-around setting for a combination of
materials and applications. This setting provides the greatest
coverage
and
best control
for internal
wetting (stabilized) and open blow applications.
Center-Down Rotation
(See illustration 9) force feeds the fiber into the airlock at a faster rate. This
direction provides the greatest
production
for cellulose fibers in an open attic blow application
although coverage may decrease.
