GMC
Evaporative
Air
Coolers
are
built
to
maximize
energy
efficiency
and
keep
costs
low.
Warm
air
is
drawn
into
the
cooler
through
a
dust
and
odour
‐
reducing
carbon
filter
and
enters
the
Cooling
Pads.
Water
pumped
from
the
tank
pours
over
the
honeycomb
cooling
pads.
As
the
warm
air
passes
through
the
media,
the
water
absorbs
the
heat,
naturally
cooling
andhumidifying
the
air.
A
fan
propels
the
cooled
air
out
into
the
room.
This
no
‐
compressor
systemcools
naturally,
efficiently
and
inexpensively.
The
recommended
maximum
relative
humidity
level
is
60%
or
less,
which
allows
a
noticeable
temperature
decrease.
The
temperature
decrease
will
be
greater
in
drier
climates
because
higher
evaporation
occurs
when
the
humidity
is
low.
The
evaporative
air
cooler
should
not
be
used
in
enclosed
spaces.
It
must
be
kept
level
and
there
must
be
water
in
the
water
tank.
The
room
should
have
doors
and
windows
opened
to
allow
free
air
flow.
The
evaporative
air
cooler
works
best
when
placed
near
an
open
window,
so
that
outside
air
is
drawn
into
the
evaporative
air
cooler,
the
air
circulates
in
the
room,
then
exits
via
the
door.
The
maximum
cooling
effect
is
felt
when
a
person
is
in
the
flow
of
air
coming
out
of
the
evaporative
air
cooler.
The
evaporative
air
cooler
can
also
be
used
to
humidify
dry
air
during
cool
weather.
To
be
used
for
humidification
the
windows
and
doors
be
closed
to
allow
the
humidified
air
to
accumulate.
