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. 

1.5 

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.

1.5.2.2

  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
