A dryer vent duct that s too long reduces the airflow and wastes energy.
Dryer exhaust booster fan problems.
Hot air from the dryer is then pushed out the exit.
If it s too long you ll have to install a booster fan that has a pressure sensor on it.
The reason is simple.
Fantech s dedpv 705 feature a wall mount indicator panel that mounts in the wall near the dryer.
Dryer vent booster fan cut the duct at a convenient location 10 ft.
If the dryer ducting is going to be more than that add a booster fan and the fan can help move the air that much further.
These problems are typically caused by long or convoluted duct runs.
Having a proper dryer booster fan is integral to maintaining the well being of your hvac system and your dryer.
The fan on the dryer will stop but you should still hear air being pulled through the dryer from the booster fan.
It gets stuck in the fan blades.
Fan and switch mounting the recommended location of the booster fan is a minimum of 15 linear not equivalent feet of duct from the dryer outlet.
This is because moist air cannot effectively exit the dryer and exhaust to the outside bogging down the entire drying process.
If a dryer s vent run is over 25 equivalent feet or the dryer is experiencing long drying time your dryer may need a dryer booster fan.
With excessive duct lengths or runs with many turns the back pressure also called pressure drop of the duct is too high.
This cuts down on the amount of air that is extracted from the dryer.
The dryer fan is capable of moving air efficiently x number of feet.
If the fan is mounted closer than the recommended 15 feet it may develop enough pressure to lift wet lint into the fan impeller resulting in excessive lint loading in the fan.
A pressure sensitive switch automatically starts the dryer vent booster fan only when the dryer is running.
Long runs need a dryer vent booster fan.
This lint can later accumulate moisture and in turn cause a whole lot of problems.
The logic behind these booster fans makes simple sense.
Booster fans should be added to any dryer duct exceeding 25 feet in length.
If it takes forever for your clothes to dry the problem could be the dryer duct.
Or more from the dryer hang the booster from a joist or stud then tape the duct to the inlet and outlet with metal tape.
An led light on the indicator panel lets the user know that the fan is operating correctly.
The fantech dryer exhaust fans have been specially designed to solve the problems caused by long duct runs on clothes dryers.
Booster fans are specially designed to solve the problems caused by long dryer vent runs.
When you activate the dryer the fan s sensor will be activated and will help push the lint and moisture.
With the dryer operating open the dryer door.
