United Air Specialists, Inc.
Supra-Blast
Cartridge Dust Collector
Revised 02/02
In the case of spark producing processes, system
design should incorporate measures to prevent live
sparks from entering the dust collector. Consult local
authorities for the location of this unit and any additional
precautions to consider when collecting combustible,
explosive or hazardous dusts. General warnings and
cautions are provided in Section 1.1.
The Supra-Blast dust collector should be mounted on a
solid, level, reinforced concrete foundation. Other
mounting options are also possible. Structural
calculations for the foundation or other mounting
arrangements must include the weight of the collected
material and the weight of all auxiliary equipment
installed with the dust collector (ductwork, abrasive
inlet, blower package, afterfilter assembly, etc.). The
Supra-Blast Specification Table in Section 3 provides
unit weights. These weights must be considered
together with wind loading, seismic loading and other
live load ratings when designing the dust collector
foundation support structure. Consult a professional
engineer when designing the foundation for the unit.
Interconnecting ductwork should be designed to include
a volume control damper for regulating system design
airflow. United Air Specialists, Inc. offers optional volume
control dampers which can be installed on the air inlet/
outlet ductwork of the Supra-Blast unit to regulate
airflow. Ductwork must be properly sized to meet the
recommended air velocities for the material being
collected.
Follow ductwork design methods as listed in the
Industrial Ventilation Manual as recommended by the
American Conference of Governmental Industrial
Hygienists.
4.3 ASSEMBLY OF STANDARD EQUIPMENT
Remove all crating, strapping and hold-down bolts.
Locate all hardware bags, sealant and other assembly
materials provided with your unit.
HOPPER ASSEMBLIES
The Supra-Blast series filter module is designed to
mount directly on top of the hopper assembly. A hopper
assembly consists of a hopper bin, legs, side diagonal
sway braces, rear diagonal sway braces, front horizontal
brace and hardware installation kit. Most Supra-Blast
hopper bins will be factory assembled with the legs and
sway bracing. Some hopper assemblies may be shipped
in pieces and will need to be assembled at the site.
If the hopper assembly is factory assembled, position
hopper and legs on the mounting pad. Shim legs as
required and secure leg assemblies to concrete
mounting pad with appropriate anchoring hardware.
Anchors should be provided by customer or contractor
according to local codes.
If the hopper sections are shipped in pieces for field
assembly, position legs as shown in “Plan Detail” on the
unit sales drawing. Bolt on sway braces using hardware
as shown in Figures 5 and 6. Leave all hardware hand-
tight; shim legs as required.
Extend hopper leg alignment bolts through leg upper
surface (refer to Figure 7, View G). Fit hopper over leg
assemblies, positioning the corner holes of the hopper
over the alignment bolts in each leg gusset corner (refer
to Figure 7, View H).
Secure leg assemblies to concrete mounting pad with
appropriate anchoring hardware. Anchors should be
provided by customer or contractor according to local
codes.
FULLY-ASSEMBLED FILTER MODULE
SECTIONS
Apply two ribbons of sealant to hopper flange to create
“figure 8” pattern around mounting holes (refer to
Figure 7, View H).
Place filter module onto hopper/leg assemblies,
positioning filter module corner holes over alignment
pins in leg gussets (refer to Figure 8, Detail K). Drift pins
will also be useful for locating the filter module section
onto the hopper.
!
CAUTION
Use adequate safety measures when lifting and
assembling any heavy components. Consult your plant
safety personnel for recommendations.
!
CAUTION
In preparing to attach the filter module to the hopper,
connect lifting slings and spreader bars to all filter
module lifting lugs with clevis pins. Use spreader bars
to distribute the load evenly. Location must be clear of
all obstructions, such as utility lines or roof overhangs.
