Pneumatics
is
a

cleaner
,
more
economical
and

to

system
to
make
mechanisms
work
.
Using
____________________
air
for
system
controlling
in
____________________
has
a
lot
of
advantages
.
Many
industries
suffer
serious
accidents
that
can
have
terrible
effects
over
the
population
and
the
environment
.
Pneumatics
is
____________________
than
other
methods
since
there
is
no
need
to
worry
about
fires
.
Transport
is
safe
as
well
,
since
pipe
lines
can
be
used
for
transporting
____________________
air
to
very
long
distances
.
This
makes
a
great
difference
with
other
methods
used
in
industry
.
Compressed
air
does
not
increase
levels
of

Air
is
the
only
product
released
into
the

Pneumatics
systems
are
easily

handled
and

.
So
,
if
it
has
got
so
many
advantages
,
why
is
compressed
air
not
used
universally
?
Obviously
,
it
has
several
disadvantages
too
.
The
most
important
one
is
that
in
order
to
install
an
air
controlled
system
very
____________________
spaces
are
needed
,
while
electrical
controls
are
really
____________________
.
A
second
disadvantage
is
that
the
release
of
____________________
into
the
atmosphere
can
be
very
