VOLU-MATIC 300
Several safety features are on the Volu-Matic 300 machine to ensure operator safety. Study the safety
section thoroughly so that all the features concerning safety are understood.
This introduction is presented to provide a basic description of the function and purpose of the
Volu-Matic 300, which will help with understanding all of the items covered in the section on safety.
The Volu-Matic 300 machine is principally designed to blow insulating materials into attics of residential and
commercial buildings, and can also be configured to spray side walls. The insulation material manufacturer’s
instructions prevail when it comes to installing their product, since they guarantee the final results.
The Volu-Matic 300 machine is normally mounted in the back of a contractor’s truck and can be powered
either by a small industrial engine or by the truck engine via a power take o (PTO) box. The belt driven
power train that drives all machine mechanisms, includes electro-magnetic clutches that provide separate
control of various functions on the machine. To allow the person installing the insulation full control of the
machine, a 12-volt electrical remote control system is provided, which operates either through the provided
hard wire remote control cord and toggle switch, or with an optional wireless remote control unit. The
Volu-Matic 300 controls provide independent control of both the air that blows the material down the hose
to its destination, and the machine mechanisms that condition and feed the insulating material into that air
stream. The machine can be set at dierent speed settings with the transmission to match the material
manufacturer’s instructions.
The 12-volt electrical circuit is powered by the machine’s small industrial engine, or by the truck battery
when it is PTO driven. The electrical control circuit is protected with a 20 amp circuit breaker. A light
illuminates when the master switch is turned on, indicating that power is on for the blower relay and remote
control receptacle. When the remote control cord switch is moved toward the cord, power is sent through
the blower relay, causing the blower clutch to engage. When the remote control cord switch is moved
toward the end of the housing, power flows to the blower and mechanism relays, causing both clutches to
engage. The toggle switch in the remote control cord housing is labeled to identify these machine functions.
The switches on the optional wireless remote control unit are labeled on the transmitter to identify these
machine functions.
The hopper area where material is loaded into the machine has a jogger and circulator to open and stir the
material, and an auger at the bottom for material feed. Material exits the hopper and is conditioned by the
shredder before entering the airlock feeder. The airlock feeder deposits the material into the air stream
where it enters the hose and flows to the hose exit.
Another feature on the Volu-Matic 300 machine is a slide gate that when adjusted, is used to control both
feed rate and material conditioning. Air Volume is controlled independently with a manually operated valve,
to help optimize material coverage.
