Fantech Dryer Booster Fans
Dryer boosting kits and lint traps. Typical residential dryers are rated at 160 cfm. 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. Fantech models DBF 110, DBF 4XL, DBF 4XLT and RVF 4XL-DB10 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.
The booster 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.

|#3||Q: How do I know if I need the lint trap with the DBF110?
A: Fantech recommends the use of a lint trap if the fan will be closer than 15 feet from the dryer. At that point the lint should be dry enough to pass through the fan.

|#4||Q: Whats better, the metal or plastic casing boosters?
A: The metal case has a better seal, but the integrated nature of the plastic one makes installation a snap. An argument could be made for either.
