Tumblers – T30 and T45

The vent collector system must be designed so the
static back pressure measured 12 inches (305 mm)
from the exhaust outlet does not exceed the maximum
allowable pressure specified on the installation sticker
on the rear of tumbler. Static back pressure must be
measured with all tumblers vented into the collector
operating.
NOTE: Never connect a tumbler duct at a 90°
angle to the collector duct. Refer to Figure 3. Doing
so will cause excessive back pressure, resulting in
poor performance. Never connect two tumbler
exhaust ducts directly across from each other at the
point of entry to the collector duct.
With the tumbler in operation, and both pockets
running, airflow at any point in the duct should be at
least 1200 feet per minute (366 meters per meter) to
ensure that lint remains airborne. If 1200 feet per
minute cannot be maintained, schedule monthly
inspections and cleaning of the ductwork.
