Adjustable Exhaust Grille
Large adjustable exhaust grille with individu-ally adjustable vanes
allows a variable airflow to be presented to the room according to
size and traffic pattern.
Safety Interlock System
Located in the channel behind the collecting cell, the micro-
switch controlled interlock system will not allow operation of the
LAF
M
without having the intake panel locked into place.
Two-Speed Fan Switch
Your LAF
M
is equipped with a three-position switch that allows
for
High
and
Low
fan speed as well as a center
off
position. The
electronic collection system and the fans are designed to run
simultaneously.
System Light
The LAF
M
is fitted with a system light which indicates
when your air cleaner is in operation. Located below the
three-position switch, the light will be lit when all
system connections are activated.
Piggyback Fuse System
The unit is provided with a fused circuit that protects
valuable components in case of a power surge. An
additional “piggyback” fuse is located in the fuse holder
for easy access if it is needed.
HOW YOUR MODEL LAF
M
WORKS
In business establishments or public buildings, millions of airborne particles are continually being circulated in the air you breathe.
Your LAF
M
Self Contained Flush Mounted Electronic Air Cleaner removes the smoke, dust, dirt, pollen, and other pollutants
from the air with an electrostatic process which works this way:
1.
The internal circulating blower mechanism
draws the dirt laden
air into the system where
it first encounters the outer PREFILTER
SCREEN.
2.
The PREFILTER SCREEN collects the
larger particles from the
air and holds them on
its intermeshed surface.
3.
In electronic units, the air then passes into
the ELECTRONIC
FILTER CELL where it
first meets the IONIZING SECTION with
its
many fine ion wires. These wires charge the
airborne particles
by
exciting them with a high
electrical charge. As the charged
particles
move along to the COLLECTING SECTION,
they are
trapped by
the collector plates much
like a magnet attracts and
collects metal fil-
ings.
4.
In HEPA LAF
M
units, the air is drawn
through a high
efficiency,
hospital grade media pad. The harmful particles are trapped and
held by the closely spaced fibers.
5.
The ACTIVATED CARBON AFTER-FILTER, the final filter in the
system,
removes odors and freshens the air.
6.
The cleaned and purified air is then
returned to the room environment.
