the air filter and receiver tank regularly. If the problem
persists, it may be necessary to change media more
often, or install an aftercooler or air dryer.
7.5.4
Absorption. Some media tends to absorb
moisture from the air, especially fine-mesh media in high
humidity-areas. Empty the media and store it in an
airtight container when cabinet is not in use.
7.5.5
Using lightweight or low-density media as noted
in Section 1.9.7.
7.6
Neither Media Nor Air Comes Out the Nozzle
During the Blast Cycle.
7.6.1
Door interlocks not engaging. Check adjustment
per Section 4.4.
7.6.2
Pressure regulator may be turned down or off.
Check pressure on regulator gauge.
7.6.3
Make sure that the air compressor is on and air-
supply valves are open.
7.6.4
Plugged nozzle. Refer to Section 7.4
7.6.5
Timer or inlet-solenoid valve malfunction.
Inspect by qualified electrician.
7.7
Blockage in Media Hose
7.7.1
Wet or damp media. Refer to Section 7.6.
7.7.2
Kink or blockage in vent hose between metering
valve and reclaimer. Make sure hose is clear.
7.8
Poor Suction in Media Hose
7.8.1
Nozzle is worn. Replace if worn 1/16" or more.
7.8.2
Blockage in media hose or nozzle. Refer to
Sections 7.4 and 7.5.
7.8.3
Air pressure too high. Reduce pressure to 80 psi
maximum.
7.9
Air Only (no media) from Nozzle
7.9.1
Nozzle pressure too high for the media, causing
media to break down.
7.9.2
Reduced air pressure decreases vacuum in
media hose, which could be caused by a malfunctioning
pressure regulator, a dirty filter element in the air filter, a
partially closed air valve, a leaking air line, other air tools
in use, or regulator pressure set too low.
7.9.3
Blockage in media hose or gun. Refer to Section
7.4 and 7.7.
7.9.4
Worn gun parts such as nozzle or air jet. Inspect
and replace all worn parts.
7.9.5
Worn media hose. Check hose for leaks and soft
spots. Replace worn or damaged hose.
7.9.6
Moist media. Frequent bridges or blockage in
the area of the metering valve can be caused by
moisture. Refer to Section 7.5.
7.10
Blowback Through Media Hose
7.10.1
Blockage in nozzle. Remove the nozzle and
check for blockage.
7.10.2
Air jet washer (Figure 21, Item 5) not tightly
sealed against air jet. Tighten the bushing into the gun
body.
7.10.3
Air pressure too high. Reduce pressure to 80 psi
maximum.
7.11 Media Buildup in Cabinet Hopper; Media
Does Not Convey to Reclaimer
7.11.1
Inlet damper closed or partially closed restricting
air movement through cabinet. Open damper per
Section 4.5.
7.11.2
Dirty filter cartridge reducing air flow through
cabinet. Inspect differential pressure gauge. Refer to
Sections 4.2 and 5.4.
7.11.3
Damaged door gaskets. Inspect and replace
damaged gaskets.
7.11.4
Blockage in flex hose between cabinet hopper
and reclaimer inlet. Inspect hose for blockage.
