MODEL #1300/2300
Mechanical Settings
Your machine contains blower and slidegate controls used to adjust your machine for each application and type
of insulation. (See Illustration H for machine model and location of controls) 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.
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 insulation. (See Illustration H) 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 insulation dropping into the airlock which
changes the production rate (lbs. per hour). (See Illustration H) 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 insulation can be blown through a
hose without plugging. These controls also affect the accurate blowing of insulation for spraying applications.
These settings control the following:
• Density of insulation 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).
