Abrasive Blasting
Media
Blasting media comes in many different
grit sizes and sometimes is also rated as
extra fine, fine, medium, coarse, and
extra coarse. The larger the grit
number, the smaller the particle size;
the smaller the grit number, the larger
the particle size. Glass media can come
in beads, crushed, or ground.
Aluminum oxide and silicon carbide can
come in several colors. It is common
today to find mixtures of glass and
aluminum oxide.
Abrasive media - not
recommended
Although available, some media are
not recommended for use because of
mechanical and/or personal hazards.
Silica sand, a common blast media, has
health risk concerns due to the silica
content. Restriction on its usage is
common in many states.
9. Position the end of the pick up tube
in the middle of the cabinet where
the blast media will be deepest.
10. Put on a NIOSH/MSHA approved
respirator.
11. Add blast media to cabinet.
12. Place item to be cleaned inside
cabinet.
13. Close and latch door.
14. Place hands in gloves, aim blast gun
at surface to be cleaned and pull
trigger.
7. Do not depress the trigger when
connecting the air supply hose.
Do not work
near flammable
liquids. Blasting media striking metal
can cause a spark and create a fire or
explosion.
Do not spray acids
or caustics.
Assembly
See Parts List for Assemby Instructions.
Operation
After the blast cabinet is completely
assembled, follow these instructions
before suppyling air to the cabinet.
1. Position cabinet on a table or
workbench where you will be
performing the work.
2. Connect air supply (max. 125 psi) to
the fitting on the side of the
cabinet (Figure 3).
3. Check for air leaks. If any are found,
repair.
4.
Plug the 12V power supply into a
110V wall outlet
.
5. Plug the other end of the 12V power
supply into the light switch on the
cabinet (Figure 3).
6. Check that the light works. It can be
rotated to prevent the light from
shining directly into your eyes.
7. Add a plastic window protector
(supplied) to the inside surface of
the glass door.
8. Make sure the material hose is
securely attached to the smaller
tube (and does not touch the larger
tube) of the metal pick up (Figure
4).
