3 Foot Print area High due to
Low Air to cloth
ratio
Less Foot
print area
than RABH
Lower than
RABH but
higher
than pulse jet
Lower than
RABH but
higher than
Pulse Jet and
Hybrid Filter
4 Effective height
of unit
High due to
long length of
bag (~ 10 mtr.)
hence total
height extends
to 25-30 mtr.
Leading to
increased
length of
ducting.
Less
Generally
Bag height is
6.5 to 8.0 mtr
with overall
height limited
to 14-16 mtr.
Generally ESP
field height is
14 mtr, overall
height limited
to 16-17 mtr.
Generally, the
field height is
14 mtr, overall
height
limited to 16-17
mtr. for ESP.
But for GCT
the height is
approx.42 mtr.
5 Weight of unit High because
of high cross
section area.

compare to
RABH
Less
compared
to RABH
but higher
compared to
Pulse Jet
Total weight
of ESP+GCT
is higher than
others
6 Insulation
quantity
Requires
more thermal
insulation area
because of
above.
Requires
moderate
thermal
insulation
area because
of above.
Less compared
to RABH
but higher
compared to
Pulse Jet
Combined
ESP+GCT is
Higher than
others
7 Bag fixing
arrangement
Requires J
hooks, thimbles
and tensioning
tools without
bag cage.
Requires only
bag cages.
Requires only
bag cages. But
also collecting
and emitting
electrode
with cleaning
arrangement
Not
Applicable
8 Bag
replacement
procedure
Lengthier due
to tensioning
arrangement
requiring
special tools
and is a skilled
job.
Easy and
fast bag
replacement.
No spe-
cial skill is
required.
