1.0 INTRODUCTION
1.1 Scope of Manual
1.1.1 These instructions cover set-up, operation,
maintenance, troubleshooting, optional accessories, and
replacement parts for INEX series suction blast cabinets
with vacuum dust collector.
1.1.2 These instructions also contain important
information required for safe operation of the cabinet.
Before using this equipment, all personnel associated
with the blast cabinet operation must read this entire
manual, and all accessory manuals to become familiar
with the operation, parts and terminology.
1.2 Safety Alerts
1.2.1 Clemco uses safety alert signal words, based on
ANSI Z535.4-1998, to alert the user of a potentially
hazardous situation that may be encountered while
operating this equipment. ANSI's definitions of the signal
words are as follows:
This is the safety alert symbol. It is used to
alert the user of this equipment of potential
personal injury hazards.
Obey all safety messages that follow this symbol to
avoid possible injury or death.
CAUTION
Caution used without the safety alert symbol
indicates a potentially hazardous situation
which, if not avoided, may result in property
damage.
CAUTION
Caution indicates a potentially hazardous
situation which, if not avoided, may result in
minor or moderate injury.
WARNING
Warning indicates a potentially hazardous
situation which, if not avoided, could result in
death or serious injury.
DANGER
Danger indicates an imminently hazardous
situation which, if not avoided, will result in
death or serious injury.
1.3 General Description
1.3.1 See Figure 1 for arrangement of components.
INEX blast cabinets enclose the blasting environment to
provide efficient blast cleaning while maintaining a clean
surrounding work area. Production rates are influenced
by size of nozzle, compressor output, working pressure,
type and size of media, angle and distance of the nozzle
from the blast surface. INEX cabinets consist of two
major components:
1. Cabinet Enclosure
2. Vacuum Collector
1.4 Theory of Operation
1.4.1 When the air supply is on, and the cabinet doors
are closed, the cabinet is ready for operation by actuation
of the foot pedal. Fully depressing the foot pedal causes air
to flow through the blast gun. Air moving through the gun
draws media into the blast gun mixing chamber. The
media mixes with the air and is propelled out the nozzle.
After striking the object being blasted, the heavier,
reusable blast media, falls through the mesh work table,
and into the cabinet hopper for reuse. Lighter weight dust
and fines that would normally remain suspended, are
drawn through the vacuum dust collector, which traps the
dust and discharges clean air. When the foot pedal is
released, blasting stops.
1.5 Nozzle Options
1.5.1 Unless otherwise specified at the time of order,
cabinets are shipped with a 5/16" orifice ceramic nozzle
and No. 5 (5/32" orifice) air jet. Optional more durable
tungsten carbide and boron carbide nozzles are
available and are shown under Accessories and
Replacement Parts in Section 8.2. Use boron carbide
nozzles when blasting with aggressive media, such as
aluminum oxide and silicon carbide.
1.6 Media
1.6.1 INEX Suction Blast Cabinets utilize most
common reusable media 25 mesh to 100 mesh, that is
specifically manufactured for dry blasting. Several
factors affecting the usable media size range are: nozzle
orifice size, air pressure, media/air mixture, media
friability, contamination of parts being cleaned, and
humidity. Media sizes noted are intended as guidelines
only, and
