MODEL #500
Mechanical Settings
The control end of your machine contains blower and slidegate controls to adjust your machine for each application and type
of fiber. (See illustration J)
Blower control
(air) and
slidegate
(material feed) are adjusted according to:
APPLICATION:
Open blow, retro-sidewall and spray-on applications require varying amounts of control.
TYPE OF MATERIAL:
Cellulose, fiberglass, and mineral fiber 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.

GENERAL BLOWER/SLIDEGATE SETTINGS:
Since specific settings need to be determined by each operator, the
following are only suggested guidelines. Consult the fiber manufacturer
for additional recommendations specific to
their
product.

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 J) The blower control dial operates clockwise,
from HIGH to LOW, controlling air pressure and amount of air.
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 J) For calibration purposes the scale
located on right side of machine indicates how many inches the
airlock slidegate is opened.
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 retro-sidewall 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:
(See illustration J)
With the
slidegate
closed, turn
agitator-feed mo-
tor on
and variable speed blower control(s) on low.
Fill hopper with insulation and adjust
blower con-
trol
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 fiber
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 proportion-
ally. This will increase the distance fiber can be
blown through the hose and improve material cover-
age 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 fiber manu-
facturer.
