Additional Components

MEDIAS:
• Review the Media MSDS
(Material Safety Data Sheet)
to ensure the material is free of
toxic or harmful substances such
as lead, silica, cyanide or
arsenic. Use properly sized
media to ensure required
surface finish.

BLAST POT:
• Inspect the Blast Pot for internal
and external wear, abrasions and
leaks.
• Ground the Blast Pot to dissipate
static electricity created by the
Media moving through the Blast
Hose.
• Install a Moisture Separator at
the Inlet Port of the Blast Pot.
Removing moisture from the
Air Supply will allow Media to
flow smoothly from the Blast Pot
to the work surface.
• Inspect abrasive trap filter and
empty trap frequently
• Inspect exhaust muffler and filter
element before starting blasting
operations. Replace filter
element if exhaust air flow is
restricted by residual dust

AIR SUPPLY: Respirator
• Inspect Respirator Assemblies
for worn components and
replace as needed.
• You MUST consult the
Operator’s Manual supplied
with your Respirator for ALL
applicable Warnings and
Hazards.

BLAST NOZZLES:
• Replace Blast Nozzles if liner
or jacket is cracked, damaged or
an orifice size 1/16” larger than
the original size.
– Determine Nozzle wear by
inserting a drill bit 1/16
”
larger than original size of the
Nozzle orifice. If the drill bit
passes, replacement is needed.
• Blast Nozzles with ½” I.D. or
1” I.D. Entry require use of a
Nozzle Washer. Wide Entry
(1-1/4” I.D.) Blast nozzles do not
require a Nozzle Washer.
Inspect and replace damaged
Nozzle Holder or Nozzle Washer
before use.

AIR SUPPLY: Blast Pot
• Use an Air Compressor that
will provide sufficient CFM
(Cubic Feet Per Minute) volume
of air to the Blast Nozzle and all
other pneumatic tools, with an
additional 50% to allow for
Nozzle wear.

AIR & BLAST HOSE:
• Inspect all Hoses for internal
and external wear, abrasions
and leaks.
• Lay out Air Hose and Blast
Hose as straight as possible to
remove restrictions which cause
reduced performance and
premature wear.
• Blast Hose I.D. should be 3-4
times the size of Nozzle orifice.
• Blast Hose and Air Hose
Couplings are to mate securely
using Gaskets to provide a
positive seal without leaks.
Inspect and replace any worn or
damaged component before use.
• Install Safety Clips and Safety
Cables at each connection.

PROTECTIVE CLOTHING:
• Wear appropriate Protective
Clothing and Equipment
(supplied-air respirator,
blast suit, safety shoes,
leather gloves, ear protection
and eye protection) appropriate
for the work environment.
