1. IMPORTANT NOTICE
This manual contains important safety information and
precautionary measures. It is impossible to list all
potential hazards associated with every dust collection
system in each application. Proper use of the equipment
must be discussed with United Air Specialists, Inc. (UAS)
or your local DUST-HOG
® representative. Operating
personnel must be aware of, and adhere to the most
stringent safety procedures.
2. INTRODUCTION
Thank you for selecting DUST-HOG ® dust collection
equipment to assist you in your commitment to a clean
and safe environment. We trust that in purchasing our
product you have recognized our commitment to
continually offer dust collection equipment engineered to
the highest standards.
The Supra-Conic ® dust collector is designed to collect
process-generated dusts. The Supra-Conic ® is a
high-efficiency, intermittent-duty, small cabinet cartridge
collector equipped with an exclusive UAS conical
cartridge filter with air distribution insert. Each
Supra-Conic
® unit is also equipped with a self-contained,
reverse air pulse cleaning system.
The Supra-Conic ® dust collector should not be used for
any purpose not listed in this manual. Refer to Figure 1
for overall Supra-Conic
® dimensional information for dust
drawer model configuration.
As you review this manual, refer to Figure 2 for
assistance in locating unit parts.

2.2 DESCRIPTION AND OPERATION
The DUST-HOG
®
Supra-Conic
®
is a high-efficiency,
cartridge dust collector designed for intermittent-duty
collection. The Supra-Conic
®
is equipped with a filter
cleaning system developed by UAS. The cartridge filter
is a conical filter with an integrated air distribution insert.
The filter is arranged in a vertical orientation to
precipitate contaminant release from the pleated filter
design. The dust collector is designed for automatic
downtime filter cleaning by means of a built-in
compressed air system (refer to Figure 2).
There are two primary modes of operation — the air
filtering operation and filter cleaning cycle (refer to
Figure 3).
2.3 AIR FILTERING OPERATION
The Supra-Conic
®
is a compact, high-efficiency, vertically
orientated dust collector equipped with a cone-shaped
cartridge filter. The unit includes a backward-inclined fan
wheel for quieter operation and higher airflow
performance, as well as a self-contained air pulse
cleaning system designed for downtime cleaning.
The contaminated airstream enters the dust collector
through the rear and/or side inlets. The airstream
velocity is reduced and channeled by a series of inlet
baffle plates which produce even dust loading distribution
across the conical cartridge filter(s). The conical shape
of the filter provides increased media surface area along
with an inherently lower pressure drop across the filter.
This allows greater external static pressure capabilities
and requires less horsepower (kilowatts) to run. The
filter media strips the dust from the airstream allowing
only the clean air to pass through the filter. The clean
airstream then moves through the tubesheet into the
lower blower chamber compartment which houses a
Goyen
®
diaphragm valve. The clean airstream is pulled
upward through a backward-inclined blower wheel and is
exhausted out the top of the cabinet.
2.4 FILTER CLEANING CYCLE
During normal operation of the intermittent-duty dust
collector, the surface of the cartridge filter(s) becomes
loaded with contaminants. Upon start-up, the downtime
filter cleaning system will automatically engage and the
air manifold is pressurized to 93 PSIG (6.5 BAR) by a
self-contained air compressor. However, the air pulse
blast does not activate until the unit is shut down. One
minute after the fan is deactivated, the diaphragm valve
will discharge 93 PSIG (6.5 BAR) of air into the center of
the conical filter for 0.5-1.0 seconds. The flexing of the
filter media and the pulse airflow breaks the collected
particles from the filter media and the particles fall
downward into the dust drawer, drum or pail. The
tapered design of the conical filter allow gravity to aid
particle removal and increase dust release.
