General Description
1.4.1
Refer to Figure 1 for arrangement of
components. The MediPulse cabinet encloses the
blasting environment to provide efficient blasting while
maintaining a clean surrounding work area. Production
rates are influenced by size of air jet and nozzle,
compressor output, working pressure, type and size of
media, and angle and distance of the nozzle from the
blast surface. MediPulse 2342se cabinet consists of two
major components.
1. Cabinet Enclosure
2. Power Module
1.4.2 Cabinet enclosure
Approximate work chamber dimensions:
42" wide x 23" deep x 30" high.
1.4.3 Power module:
300 CFM Power Module is attached to the back of the
cabinet enclosure and includes:
• 300 cfm reclaimer
• 300 cfm reverse-pulse cartridge dust collector
1.5
Theory of Operation
1.5.1
Once the cabinet is correctly set up and turned on,
the cabinet is then ready for operation by actuation of the
foot pedal. Fully depressing down on the foot pedal causes
air to flow through the blast gun. The partial vacuum
created by air moving through the gun draws media into
the blast-gun mixing chamber. The media mixes with the
air stream and is propelled out the nozzle. After striking the
object being blasted, the blast media, fines, dust, and
byproducts generated by blasting fall through the grate into
the cabinet hoppers. These particles are then drawn into
the reclaimer for separation. Dust and fines are first
separated from reusable media and pass into the dust
collector. Next, the media is screened for oversize particles
and returned to the reclaimer hopper for reuse. Dust and
fines entering the dust collector are removed from the air
stream as they pass through the filter, discharging clean
air. When the foot pedal is released, blasting stops.
