The Dryer Facts:
When it comes to dryers, where is the perfect installation
with little to no duct length? The reality which contractors and homeowners have
to work with is far from perfect. A short dryer duct length is not always
possible. This is where Fantech Dryer Boosters can help.
Under prime conditions,
residential and commercial clothes dryers should dry clothing in a timely
fashion. Problems occur when dryers are connected to long runs of duct work.
This is the reason why most residential dryers are located against outside
walls. The exhausted air is vented directly to the outside without complicated
ducting to hinder the performance of the dryer.
Many dryer installations
do not allow direct venting and the typical residential dryer cannot operate
efficiently against the resistance created by the necessary duct work. The
results are longer drying times, higher energy usage and costs, and excessive
wear and tear on the dryer.

TYPICAL FAN PROBLEMS:
- Conventional types of booster fans present
- Their blades clog with lint
- The blower cannot handle the long runs of
duct any better than the blower in the dryer
- The motor cannot handle the heated air from
the dryer and tends to overload
- How to turn the booster fan on with the dryer
When to boost a dryer.
Typical residential dryers
are rated at 160cfm. However, boosting is generally needed in order to maintain
a minimum airflow of 100cfm as duct length increases and bends are introduced in
the duct line.
Based on surveying the
recommendations from dryer manufacturers, and local building codes in selected
areas, dryer boosting is typically required when the duct length exceeds the
Fantech models DBF 110, DBF 4XL
and RVF 4XL are all suitable for most dryer boosting applications. Generally the
models listed can be used for maximum duct length of 60 linear feet with a
maximum of six elbows using four inch rigid duct. For longer duct runs please
contact our technical department for specific recommendations.
110 (FR110 Fan) Dryer Booster Fan
The DBF 110 Dryer
Booster inline fan addresses every obstacle. A silent partner for your
dryer. The fan compensates for system duct losses and allows the dryer to
exhaust warm moist air as the manufacturer intended. The fans can handle up
to 60 feet of duct and six elbows. The backward blades allow lint to pass
through the fan. The patented control automatically operates the booster fan
whenever the dryer is running.
