many dryer installations are located in interior, convenient
to the kitchen locations and actually too far from the exterior
for traditional exhaust duct work. Too long of a run results
in longer drying times, higher energy usage and reduced air
flow velocity in the exhaust, accelerating lint buildup in the
The Fantech DBF110 Dryer Booster Fan is specially designed
in two important ways. One, the fan blades are a true
airfoil backward curved impeller eliminating the risk of lint
buildup on the blades, and two, the fully automatic pressure
switch. The switch monitors dryer operation and will
activate the fan when the dryer comes on. Preset to
cycle in ten minute intervals the fan will stay on until the
dryer stops. The DBF-110 dryer booster fan is suitable
for rigid duct runs of up to 60 linear feet with a maximum
of six elbows.
In some instances, you may use long-turn elbows as an alternative to booster fans. For more information,

A very innovative fully automatic dryer booster fan with a
onboard pressure switch sensing when the dryer is running.
A Fantech Lint Trap is suggested when the booster fan must
be located closer than 15' from the dryer.
