Fantech DBF4XL Dryer Boosting Kit with Galvanized Steel Fan
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.
The DBF 4XL features our FX4XL fan with a housing made from galvanized steel, suitable for most commercial applications. The fans can handle lengths of duct up to 60 feet and six elbows. The backward inclined blades allow lint to pass through the fan. The patented control automatically operates the booster fan whenever the dryer is running. Includes 5 foot installed power cord with plug.
Includes 148CFM 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.

Installed easily. Instruction vague on mounting bracket to fan. My wife used the dryer and told me reduced dry time by about 1/3rd

Comments about Fantech DBF4XL Dryer Boosting Kit with Galvanized Steel Fan:
[...]. It was fairly easy to install and works as expected. I think this product is a good value.A warning though, you might want to clean out the dryer duct work before installing. I only did a superficial job of cleaning the ducts before installing the booster. The dryer booster apparently did the rest of the cleaning for me and in the process was clogged with lint. The booster immediately became very noisy and vibratory. After removing the intake duct and cleaning out the product, it was nice and quiet again and has been since -- about three months.

This product worked exactly as advertised. Excellent solution for long dryer duct runs. I also installed the Fantech DBLT 4 Dryer Lint Trap and was glad I did. It catches a lot of lint missed by the dryer lint trap. Really helps keep the duct run clean.

This unit is easy to install and helped my clothes dry in a single cycle now. I always had to go an extra 20 minutes prior to installing this fan. I have about a 30 ft of dryer vent pipe with several elbows in it. This fan helped immensely.

Comments about Fantech DBF4XL Dryer Boosting Kit with Galvanized Steel Fan:
I just finished the laundry room. The booster fan was installed in 60 feet of duct with 4 elbows. Right at it's maximum capacity. When the dryer was turned on, the booster turned on like it was suppose to and a large air flow was coming out of the exhaust vent. The motor is quit even though it is mounted directly to the floor joists. I did use the mounting clamps which I believe helped reduce any vibration. The clamps were not the easiest to use, but are ok. I did not have any problem with using the mounting screws. I just made sure the were at the edge of the housing.Also, IAQSource was excellent to deal with. [...]

Comments about Fantech DBF4XL Dryer Boosting Kit with Galvanized Steel Fan:
Immediate impact. I had a terrible dryer vent layout, roughly 25 feet with 8 - 90 degree bends. I cut out 3 of the bends, and installed the fan, and my drying times have reduced from nearly 3 hours, to around 30 minutes. Having two roommates, I can't explain how much this helps with fights over the laundry. The ease of having a standard electrical plug is great for installation. I love the second lint trap as well.

Relatively easy installation. This is a well made metal unit. Between cleaning my ducts and installing this unit drying times dropped from 3 cycles of dryer/load to sometimes as low as one. I'm impressed.

Comments about Fantech DBF4XL Dryer Boosting Kit with Galvanized Steel Fan:
We had a long dryer vent run (about 40 feet) and noticed that our dryer took a very long time to dry. The vent fan has significantly reduced drying times. We feel it is well worth the time and trouble to install it.
