MODEL #1300/2300
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 direction can be adjusted as described below.
Unidirectional Rotation (See illustration I) is preferred as an all-
around setting for a combination of materials and applications. This
setting provides for the greatest coverage and best control of the
fibers in wall cavity spray, commercial spray, internal wetting (stabi-
lized) and open blow applications.
Center-Down Rotation (See illustration J) force feeds the insulation
into the airlock at a faster rate. This direction is preferred for the
greatest production of various insulation in an open attic blow applica-
tion although coverage may decrease. This setting will provide ample
coverage and good control of the insulation in wall cavity spray, com-
mercial spray, internal wetting (stabilized) and open blow applications.
Mechanical Settings (cont.)
GENERAL BLOWER CONTROL AND SLIDEGATE SETTINGS FOR OPEN BLOW: (See Illustration H)
With the slidegate closed, turn agitator-feed motor on and variable speed blower control(s) on low. Fill
hopper with insulation and adjust blower control and slidegate. In making adjustments, move controls
proportional to each other. (i.e. If variable speed blower control is half speed, slidegate should be half open.)
Open slidegate to allow insulation to drop into the airlock providing good production, but not beyond point where
hose plugs. As hose length is increased, the blower control speed is increased while closing the slidegate
proportionally. This will increase the distance insulation can be blown through the hose and improve material
coverage rate, while decreasing the blowing production rate (lbs. per hour blown). These adjustments are for
open blow. If specialty application or retro sidewall work is done, refer to General Blower/Slidegate Settings chart
(below left) or insulation manufacturer.
GENERAL BLOWER/SLIDEGATE SETTINGS:
Since specific settings need to be determined by each operator, the following are only suggested guidelines.
Consult the insulation manufacturer for additional recommendations specific to their product.
APPLICATION BLOWER CONTROL SLIDEGATE
Open Blow High Full Open
Sidewall-Retrofit Low-Med 1/3 Open -Half Open
Wall Cavity Spray Medium Half Open
Commercial Spray (Adhesive) High One-third Open
(Illustration J)
(Illustration I)
(Illustration K)
Center-Up Rotation (See illustration K) is preferred for extended
coverage on mineral fiber. Note: For this application an upgrade
kit will be needed.
