1. IMPORTANT NOTICE

this manual contains important safety information and
precautionary measures. it is impossible to list all potential
hazards associated with every air cleaning system in
each application. Proper use of the equipment must be
discussed with United Air Specialists, Inc. (UAS) or your local
Representative. Operating personnel must be aware of, and
adhere to, the most stringent safety procedures.

2. DESCRIPTION

This unit is a self-contained, two-stage, air cleaner designed
to remove dry or oily airborne contaminants from industrial
work areas. operating on the principle of electrostatic
precipitation, it pulls air past a mist-stop pre-filter, charges and
collects airborne particulate, then exhausts clean air to the
environment.
Mist-stop pre-filters serve the dual purpose of trapping
large particles and diffusing the air stream evenly into the
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 startup are trapped on an after-
filter, allowing clean air to pass through the system blower at
all times.
the Model MSH may be ducted directly to the contaminant
source or un-ducted to remove particles from the general
environment.
2.1 SYSTEM COMPONENTS
1. Mist Stop Filter
the Mist Stop filter is a pre-filter used to remove large
particulate and aids in diffusing the air entering the eSP
section.
2. High Voltage Power Supply
the power pack contains the necessary components to
convert customer provided input power (see section 1)
to the high-voltage Dc required for the ionizer and
collection cell.

To ensure both equipment and personnel safety, the power
supply high voltage output circuit is limited to a maximum
of 5.0ma when using power-pack 21-1216 and 5.6ma when
using power-pack 21-1234.
In the event of a short circuit or other overload condition,
the power supply is designed to cause the high voltage to
collapse. When the voltage collapses, the indicator light
will blink. When the overload is removed, the voltage will
automatically build up to normal and the indicator light will
illuminate. the power supply is self-protecting
against overload.
When the power is removed from the power supply circuit,
FLA
an internal resistor bleeds off the residual charge on the
collection cell. As a precaution, when the access door is

opened, the blade of an insulated handle screwdriver
2 9 .
should be used to ground components before removal
(see grounding procedure, figures 5 & 6).

3. Unicell Ionizing & Collection Section
5 3 .
the ionizing section supports thin tungsten wires which carry
a positive charge of approximately 11 KVDC. This section
electrically charges (ionizes) the contaminated particles being
pulled through the unit.
the collection section contains plates alternately charged to
a positive voltage of approximately 5.5 KVDC. This section
collects charged particles passing through the ionizer.
4. Air Mover
The motor/blower pulls in the contaminated air and exhausts
the clean air through the outlet.

3. INSTALLATION

3.1 INSPECTION NOTE

Upon receipt of your unit, check for any shipping damage.
a damaged carton indicates that the equipment may have
received rough handling during shipping that may have
caused possible internal damage. notify your delivery carrier
and enter a claim if any damage is found.

3.2 INSTALLATION PLANNING

Locating the Unit: consideration must be given to the
placement of the precipitator to maximize its effectiveness.
When your SMoG-HoG® is used as a ducted source
collector, the enclosure or pickup hood design is important
for adequate capture of contaminants. Model MSH blowers
have limited static pressure capacity. check with factory for
anticipated duct losses in excess of 0.5 inWC (12.7 mmWC).
