Empire Abrasive Equipment Company
Damp media (If media
stays formed in a ball after
squeezed in the palm of
the hand, it is too damp to
flow properly).
Remove damp media from system and
replace with new, dry media. Check
compressed air supply filters. Do not
blast wet or oily parts.
Suction System:
Improper air jet nozzle
combination.
Nozzle orifice size must be twice the
air jet orifice size 1/8”diameter air jet
requires minimum ¼” diameter
nozzle.
Suction System:
Media hose improperly
installed.
Adjust media hose in media regulator.
Check media hose at entry to the
suction gun body, hose clamp nut, o-
ring, and hose must create an air
tight seal.
Suction System:
Clogged media hose.
Remove media hose from media
regulator at the bottom to the media
storage hopper, bring that end of the
hose through an open door and into
the cabinet. Remove the nozzle from
the suction gun, insert the blow-off
gun nozzle in the open end of the
media hose, and blow accumulated
media and/or debris out through the
suction gun.
Pressure System:
Sure-Flo media regulator
closed.
Adjust media regulator.
Pressure System:
Leaking sealing plunger
and/or exhaust valve.
Check for compressed air leaks and
repair.
Pressure System:
Sure-Flo media regulator
obstructed.
Open Sure-Flo media regulator to full
open, close the choke valve, remove
blast nozzle, set blast pressure at 70-
80 PSIG and attempt to blast. All air
will be forced through the media
regulator clearing the obstruction. If
media flow problems persist, shut off
and lock out compressed air supply,
disassemble media regulator and
clear obstruction.
