General Description
1.4.1
BNP
®
blast cabinets enclose the blasting
environment to provide efficient blasting while
maintaining a clean surrounding work area. Production
rates are influenced by size of nozzle, compressor
output, working pressure, type and size of media, and
angle and distance of the nozzle from the blast surface.
BNP suction cabinets consist of three major components:
Cabinet enclosure
Reclaimer
Dust collector
1.4.2 Cabinet enclosure:
This manual covers two
BNP cabinet sizes.
BNP 6012
Approximate work chamber dimensions:
58" wide x 58.5" deep x 53" high.
BNP 7212
Approximate work chamber dimensions:
69" wide x 70.5" deep x 63" high.
1.4.3
Refer to Figure 1 for arrangement of components
with a CDC-1 Dust Collector. The illustration shows a
freestanding 900 reclaimer. 1200 and 1800 cfm reclaimers
have minor differences. Figure 2 shows the arrangement
with an RPC-2 Reverse-Pulse Dust Collector with dust
drawer. The optional RPH is set up the same way as the
RPC-2, but includes a hopper for additional dust storage
and empties into a drum. The overall height of an RPH-2 is
approximately 10.5 feet and 12 feet when the top access
door is open. To upgrade, an RPC-2 or RPH-2 Dust
Collector may be added at any time.
