1.4 General
Description
1.4.1
This manual covers two Power Gun models.
Both models are available with or without the cart and 3
cuft hopper.
Conventional Power Gun: limited to dry blasting only.
Power Gun Model H2O: can be used for dry blasting and
has water connections to add water into the blast
stream.
1.4.2
Power Guns are ideally suited for light-duty,
small, and touchup blasting jobs. The performance of the
Power Gun approaches that of a small pressure system,
but does not require a pressure vessel nor does it require
the setup time and maintenance of a pressure system.

Components and Operating Principles
1.5.1 Components
1.5.1.1
Components of the Power Guns are shown in
Figure 1, the gun assembly is shown in Figure 2, and the
additional parts for the Model H2O wetblast gun
assembly are shown in Figure 3.
1.5.2 Operating
Principles
1.5.2.1
When compressed air is supplied to the gun and
the trigger is pulled, air flows through the gun, creating a
partial vacuum in the material hose. As a result, abrasive
is drawn into the lance, through the material hose, and
into the mixing chamber. Abrasive mixes with the air
stream within the mixing chamber and is propelled
through the nozzle onto the surface being blasted.

Besides being an effective dry blaster, additional
parts provided with the H2O model (shown in the insert
in Figure 1 and Figure 3) include a water jacket and
hose, which attaches to a municipal water supply
(faucet). When the water supply is turned ON, the water
valve allows the operator to turn water ON and OFF and
regulate the amount of water added into the mixing
chamber and blast stream. Water entering the blast
