Multiple Dryer Venting
A main vent can be used for venting a group of dryers. The main
vent should be sized to remove 5663 l/min. (200 CFM) of air per
dryer. Large-capacity lint screens of proper design may be used in
main vent if checked and cleaned frequently. The room where the
dryers are located should have make-up air equal to or greater than
CFM of all the dryers in the room.
Unobstructed air openings are required for make up combustion
air. A static opening of 24 square inches (1 inch
of burner) is the minimum required for each dryer in operation.
A common opening may be used if the return air is distributed
equally to all dryers in operation.
Back-draft Damper Kit is available from your distributor and should
be installed in the vent of each dryer to keep exhausted air from
returning into dryers and to keep exhaust in balance within main
vent. Unobstructed return air openings are required.
Each vent should enter the main vent at an angle pointing in the
direction of the airflow. Vents entering from the opposite side
should be staggered to reduce the exhausted air from interfering
with the other vents.
Air ow
The maximum angle of each vent entering the 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
damage dryers and items being dried.
A clean-out cover should be located on the main vent for periodic
cleaning of the vent system.
