D r yer Booster Fan
Distributed by:
The Fantech DBF4XLT Dryer Booster Fan has been specially
designed to solve the problems caused by long duct runs on
clothes dryers.
According to dryer manufacturers and some local building
codes, booster fans should be added in the dryer duct run when
the length of the duct exceeds 24 feet with no bends, 20 feet
with one bend or 15 feet with two bends.
HOW DOES IT WORK:
When the dryer is on, Fantech’s patented pressure sensing
switch automatically turns the booster fan on. The warm, moist
air in the dryer duct is exhausted out of the building quickly.
The dryer booster fan monitors the status of the dryer and will
turn itself off when the dryer stops.
Wall mounted indicator panel with LED display lets homeown-
ers know that fan is fully operational.

nect the indicator panel to the booster fan.
