MechanicalSettings:
The controls of your machine contain the blower and slidegate controls to adjust your machine for
each application and type of fiber. (See illustration 7 on page 17.) Blower control (air) and slidegate
(material feed) are adjusted according to:
TYPEOFMATERIAL: Cellulose and fiberglass have different textures and densities that
respond to machine settings.
HOSE: Corrugations or roughness of interior surface, diameter, length and
elevation of hose will also require varying adjustments.
WEATHER CONDITIONS: Temperature and humidity may require day to day adjustment of
machine settings.
Blower Control and Slidegate General Settings:
Blower control can increase or decrease the amount of air in the system, affecting the velocity
(speed) and spread rate (coverage) of fiber. (See illustration 7 on page 17.) The blower control valve
is used for controlling air pressure and amount of air flow.
Opening or closing slidegate (material feed) controls the amount of fiber dropping into the airlock
which changes the production rate (lbs. per hour). (See illustration 7 on page 17.) For calibration

The blower and slidegate controls working together
affectthe distancefiber canbeblown througha hosewithout
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.
