3.0 CUBIC FOOT C-SERIES BLAST POT

WWW.MARCOUSA.COM
Figure 1
See Media Consumption Chart
for consumption rates and
required air flow (cubic feet per
minute). The system must meet
these minimum requirements
to ensure proper function and
performance.
*Media consumption is based on media with a bulk density of 100 lbs per Cu. Ft..
Blasting at optimal pressure
for the media used is critical
to productivity. Example: for a
media with an optimal blast-
ing pressure of 100 psi at the
nozzle, one pound per square
inch of pressure loss will reduce
blast efficiency by 1.5%. A 10
psi reduction in air pressure will
cause a 15% loss of efficiency.
Use a Needle Pressure Gauge to
identify pressure drops in your
system. Consult with your media
supplier for the requirements of
your media.
When it comes to media & air mixtures, more is not necessarily better. Optimum blasting efficiency
takes place when a lean media & air mixture is used. To correctly set the metering valve, begin with
the valve fully closed and slowly increase the amount of media entering the airstream. As you increase
the media flow, watch for a "blue flame" (Figure 1) at the exit of the nozzle. Faster cutting, reduced
media consumption and lower clean up costs, are benefits of the "blue flame".

Replace Blast Nozzle if liner or
jacket is cracked or damaged.
Replace nozzle if original orifice
size has worn 1/16" or more.
Determine nozzle wear by
inserting a drill bit 1/16" larger
than original size of nozzle
orifice. If drill bit passes
through nozzle, replacement is
needed.
Inspect nozzle before placing in
service. Damage to nozzle liner
or jacket may occur during
shipping. If you receive a
damaged nozzle, contact your
distributor immediately for
replacement. Nozzles placed
in to service may not be
returned. Nozzle liners are
made of fragile materials and
can be damaged by rough
handling and striking against
hard surfaces. Never use a
damaged blast nozzle.
