1.6 Reverse-Pulse Dust Collector Options
WARNING
All dust is hazardous to breath. Emissions can
occur from the dust collection system. Identify
all materials that are to be removed by blasting;
if any toxic materials such as lead dust or dust
from other heavy metals and corrosives, or any
other toxic materials are being removed, use a
HEPA afterfilter to assist in maintaining
inhalation hazards below the permissible
exposure limits (PELs). Prolonged exposure to
any dust can result in serious lung disease and
death. Short-term ingestion of toxic materials
can cause serious respiratory injury or death.
Filtration may not be adequate in reducing all
inhalation hazards. It remains the employer or
user’s responsibility to ensure all emissions are
safe to breath.
1.6.1 CDC-1 Dust Collector: Shown in Figure 1, the
collector is available in 300 and 600 models. The single
filter cartridge is cleaned by using a manually-controlled
pulse of compressed air. Dust collects in a 5-gallon dust
drum and must be frequently emptied CDC-1 Dust
Collectors are standard with BNP cabinets unless an
optional RPC-2 Dust Collector is ordered at time of
purchase. Refer to manual number 28225 for operation
of the CDC-1 Dust Collector.
1.6.2 RPC-2 Dust Collector: Shown in Figure 2, this
collector is available in a 600 cfm model. Dual filter
cartridges are automatically cleaned by a timed, periodic
pulse of compressed air. Dust collects in the draw must
be frequently emptied. Refer to manual number 22788
for operation of the RPC-2 Dust Collector.

1.6.3 HEPA (high-efficiency particulate air) Filter:
An optional HEPA afterfilter provides additional filtration
and must be used with a reverse-pulse cartridge
collector when removing toxic coatings, heavy metals, or
any other toxic materials. Refer to the applicable dust-
collector manual noted in Paragraph 1.1.1 for the HEPA
option.
1.7 Nozzle Options
1.7.1 Unless otherwise specified at the time of
purchase, the cabinet is provided with a No. 5 (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 BNP
Gun and Feed Assembly in Section 9.3. Use a boron
carbide nozzle when blasting with aggressive media, as
noted in Section 1.9.4.
1.8 Reclaimer Options
1.8.1 Replaceable rubber reclaimer liners: Rubber
liners are available for 600 cfm reclaimers that have a
removable top and are designed to accept liners. Liners
are not available for 300 cfm reclaimers. The liners
prolong service life of the reclaimer and should be
installed when using silicon carbide, aluminum oxide, or
other aggressive media, as noted in Section 1.9.4.
Rubber liners are shown on Page 30, Figure 31.
1.8.2 Externally adjustable vortex option: Not
available for 300 cfm reclaimer. The vortex is available
for 600 cfm reclaimers only. It fine-tunes media
separation; refer to Section 5.5 for additional
information. The vortex is an option when the cabinet is
provided with a CDC-1 Dust Collector but is standard on
600 cfm reclaimers when the cabinet is provided from
the factory with an RPC-2 Dust Collector.
1.9 Blasting Media
1.9.1 Always use media specifically manufactured for
blasting and that are compatible with the surface being
blasted. Media produced for other applications may be
inconsistent in size and shape, contain particles that
could jam the media metering valve, or cause irregular
wear. Always obtain the safety data sheet (SDS) for the
blasting media prior to blasting and identify material
being removed by blasting, paying particular attention to
worker health risks and presence of any hazardous/toxic
substances.
Most common reusable media specifically manufactured
for blasting can be used in ZERO cabinets. The listing of
media sizes shown in this section and in Figure 3 are
provided as a guideline only. The guideline is based on
standard 5/32" orifice air jet with 5/16" nozzle and
average conditions with variables such as blast
