Fantech Dryer Booster Fans solve the problems caused by long duct runs on clothes dryers. How do they work? When the dryer turns on, the fan is activated by the automatic presure sensitive switch so warm, moist air is exhausted out of the house quickly. Suitable for dryer runs with up to a maximum 60 linear feet of 4" rigid duct with six elbows. Includes 167CFM fan, pressure switch, and mounting bracket with hardware.
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. Some common examples are:
Basements that do not allow direct venting.
Central interior located residential laundry rooms.
Apartment complexes with centrally located laundering areas.
Apartment complexes with individual hook-ups for dryers in each apartment.
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 following:
Maximum duct length with: No bends - 25' 1 bend - 20' 2 bends - 15' 3 bends - 10'
A Word on Installation... Easy! The secret is in the fully automatic pressure switch. Designed to attach inline near the booster fan the 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. All Fantech dryer booster fans are suitable for rigid duct runs of up to 60 linear feet with a maximum of six elbows. In all installations there needs to be at least 15 linear feet of duct between the booster fan and the dryer.
The Fantech DBF110 is an efficient booster fan for dryers with long duct runs. The instructions and diagrams make for a troublefree installation. I have this installed in the living area of a loft and the motor is so quiet you don't even notice when it is in use.
My wife works for a PT company that was having problems with their residential electric dryer. They wash and dry towels pretty much all day long. They were having condensation problems, water was filling up the flex hose behind the dryer and they also were having ceiling leaks in a couple of their rooms. They had duct cleaners come out several times, usually helping for only a few days. They had their building maintenance look into the problems also, with no results.
My wife asks me if I would take a look at it. I found several minor issues, but the main problem was that the duct run (adding bends) was 47 feet to the exterior! I did some research online for booster fans, the first site that popped up was Fantech. After reading some of the reviews, I decided to try the DBF110 model and cord. I installed the fan about 15 feet away from the dryer and changed some the 90 degree bends to 45's.
Two weeks had past since I had installed the fan and hadn't heard of any problems. Just out of curiosity, I decided to check the fan and flex hose myself. Keep in mind, that before I had done anything to the system, they were removing the flex hose about every couple of days and dumping out about a quart of water!
The fan and ductwork was about 99% dry. When I removed the flex hose It was BONE dry!! I have to admit, I didn't think it would work this good. I think one of the key factors to its success is the fact that even after the dryer shuts off, the booster fan still runs for an additional 10 minutes, which helps dry the duct. I would recommend this fan to anyone having condensation problems!!!!
I relocated the clothes dryer but it exceeded the electric code for venting a dryer. I installed the Fantech dryer to boost the dryer output. Installation requires a skilled DIY and takes about two hours. The booster senses when the dryer comes on and then the booster turns on automatically. I was delighted when the booster worked perfectly right after installation.
Had almost no flow for dryer vent because my home builder had horrible contractors work on our home. I had to pull out the old duct work because it destroyed a $1600 HE dryer by blowing out the heater core. This was due to several years of poor ventilation through the dryer vent duct work. After paying to have dryer repaired and then installed the new Fantech booster....WOW. Solved problem and now three hours per load has been reduced to like an hour and a half to two hours for all laundry to be done!!!! Recommend this company and product to anyone!

Comments aboutFantech DBF110 Dryer Boosting Kit:
Nice system, self regulating and easy to install, The directions are clear and written by someone with a handle on the English language and owns a spell checker. The pressure differential switch is elegant.
I installed a dryer vent run that previously ran into the garage up through the garage roof. Then our clothes took forever to dry. Installed the fan and problem solved.
I built our house around 3 years ago and the only place to vent our dryer was about 30 feet away on the back of the house. I have lived with the dryer taking around 3 hours to dry a load of clothes (a contractor's house always gets fixed last). I installed this unit and now in about 45 minutes all dry. Great product almost silent and very powerful.
