Smog-Hog
SG Series Model
1. HOW THE SMOG-HOG SG SERIES
WORKS
the SG is a self-contained air cleaning system which
removes dry or oily airborne con taminants from
industrial work areas. operating on the principle of
electrostatic precipitation, it pulls air past a mechanical
prefilter, charges and collects airborne particulate, then
exhausts clean air to the environment.
Prefilters serve the dual purpose of trapping large
particulate and diffusing the airstream evenly into
precipitator components at low, controlled velocity.
air passes through an ionizing section, where nearly
all particulate is charged, then on to a collecting
section where charged particles are repelled from
similarly charged plates and drawn to ground plates.
agglomerated particles separated from collection plates
during unit start-up are trapped on an after filter, allowing
clean air to pass through the system blower at all times.
SG units may be ducted directly to the contaminant
source or unducted to remove particulate from the
general environment. units are gen erally suspended
from the ceiling but may be cradle or skid mounted to
suit the application. units without blowers are supplied
where air is moved through the units by others.
The Smog-Hog SG uniquely combines high airflow
and high efficiency. its compact “unicell” design
helps minimize contaminant by-pass. it is suitable for
operation with or without in-place cleaning. all SG units
supplied with blowers have ad justable louvers to direct
exhaust air as required.
ionizing and collecting sections operate on high Dc
(direct current) voltage and low amperage, yielding a
very low power consumption of 75 watts maximum per
power supply. the high voltage creates a powerful field
for trapping small to submicronic particles. at start-up,
the unit’s power supply charges each unicell while the
system blower begins to move air through the unit.
2. INSPECTION OF EQUIPMENT
upon receipt of your SMoG-HoG SG, check carefully
for possible shipping damage. (any damage to carton,
skid, etc., may be a warning to you that rough handling
has caused internal damage.) units supplied with
accessories, such as an in-Place cleaning System,
will arrive in multiple cartons. check cartons versus
bill of lading. the detergent container is shipped
independent of units.
notify your delivery carrier and enter a claim if any
damage is found.
3. INSTALLATION PLANNING
3.1 UNDUCTED OR AREA CAPTURE
consideration should be given to the placement of the
precipitator to maximize its effectiveness. The number
of units required to clean the air will depend on the
layout of the room and the con centration of pollutants.
Because it is necessary to develop proper airflow patterns,
the placement and number of precip itators should be as
suggested by uaS or your local representative.
3.2 DUCTED OR SOURCE CAPTURE
When your SG is used as a ducted source collector,
the enclosure or pick-up hood design is important for
adequate capture of con taminants. Drive pulleys and
belts have been selected to provide proper airflow at
the design static pressure specified. Pulleys and belts
should not be replaced without first contacting uaS
customer Service at 1-800-252-4647.
3.3 SPECIFICATIONS
Smog-Hog SG Series are self-contained, two-stage,
Penney-type, electrostatic precipitators complete
with fully interlocked, energy limiting uL “recognized
component” power packs, mechanical prefilters, unicell
construction (combination ionizer and collection cell),
afterfilters, indicator lights and interlock switches. all
models except those designated “X” are supplied
with motor/blower sets mounted in an integral blower
housing. All high voltage wiring is external to the
component enclosure.
