An exhaust hood should cap the
exhaust vent to prevent
exhausted
air
from returning
Into the dryer. The
outlet
of the hood
must be at least
12 inches (30.5 cm) from the ground
or anything
else that may be in the
path of the exhaust.
Four-lnch outlet hood is preferred.
However,
a 2-1/2-inch
(6.4 cm) outlet
exhaust hood may be used. A
2-1/2-inch
(6.4 cm) outlet creates
greater
back pressure than other
hood types. For permanent
installation,
a stationary
exhaust
system is required,
A main exhaust vent can be used for
exhausting
a group
of dryers. Main
exhaust
vent should be sized to
remove
200 CFM of air per dryer.
Large-capacity
lint screens of proper
design
may be used in the main
exhaust vent if checked
and cleaned
frequently.
The room where the dryers
are located
should have make-up
air
equal
to or greater
than the CFM of
all the dryers in the room.

air from interfering
withtheother
vents.
The maximum
angle of each vent
enteringthe main vent should be no
more than 30°.
Keep air openings free of dry
cleaning
fluid fumes. Fumes create
acids which, when drawn through the
dryer heating units, can damoge
dryers and loads being tided.
A clean-out
cover should be located
on the main exhaust vent for
perlodicalty cleaning of the exhaust
system.
An exhaust hood should cap the
outside end of the main vent to
prevent
exhausted
air from returning
to the dryers. If an exhaust hood
cannot
be used, the outside end of
the main duct should have a sweep
elbow directed
downward.
If the
main vent travels vertically
through
the roof, rather than through
the wall,
install 180° sweep elbow
on the end
of vent at least 2 feet (61 cm) above
the highest part of the building.
The
opening
wall or roof shall have a
diameter
1/2 inch (1.3 cm) larger than
the exhaust vent diameter.
The
exhaust vent should be centered
