SOLUTION
DRYER BOOSTER FANS are specially
designed to solve the problems caused by
long duct runs on clothes dryers. Long duct
runs with multiple elbows can cause
extended drying time as well as lint and
moisture build-up within the dryer duct.
WHEN IS A DRYER BOOSTER
NECESSARY?
According to some dryer installation
instructions and local building codes,
booster fans should be added in the
dryer duct run when the length of the
duct exceeds 25 feet with no bends,
20 feet with one bend or 15 feet with
two bends.
Dryers were designed to be located on
an outer wall and directly vented out of
the building. In today’s home, condo and
apartment designs the laundry has been
moved to interior locations causing the
use of extensive lengths of duct. Most
typical dryers cannot operate efficiently
against the resistance created by the
necessary duct work. In these applications
a dryer booster fan is the perfect solution.
Exclusive Wall-Mount
Panel with LED Light
assures homeowner
that booster fan is
working normally.
HOW DO THEY WORK?
When the dryer is on, Fantech’s patented
pressure sensing switch automatically
turns the booster fan on. The
FIVE
warm, moist air in the dryer YEAR
WARRANTY
duct is exhausted quickly.
CALCULATING DUCT RUN
To calculate the length of your planned
duct run, measure from the dryer to the
external venting point in roof or wall.
For each bend or elbow add 5-7 feet to
your total duct run calculations. All of
Fantech’s Dryer Boosters can be used on
runs up to 130 feet except the DBF110
which is effective up to 108 feet.
Always consult local codes before installation.
NOTE: If booster fan is located within 15 linear
feet of the dryer, a DBLT4 Lint Trap should be
added between the dryer and the fan.
