Review: Worth every penny! Dry times are now down to 40-60 minutes vs. nearly 2-3hrs on large loads! - UPDATED 8/6/15: Still LOVE this unit, and it has continued to work flawlessly! I had marked my phone's calendar for the one year mark since installation as a reminder to crawl under the house (where I installed it) take it apart and clean it, clean the exhaust vent as well (as best as I could) and put it back together as general maintenance. I'm glad I did, as the unit had some build up lint for sure inside of it. Not that you would know it, as it continued to run perfectly, but could've perhaps reduced the life of the unit had it gone too long, I don't know. Anyways, quick and easy to uninstall, clean, and reinstall, and I reset my calendar for another year and I should be good to go. Definitely recommend this to anyone with poor drying due to long vent runs. ----------------------------------------------------------------------------------------------------------- I typically don't write reviews, but I wanted to share how incredibly well this unit works for us and for the price is worth every penny! A quick back story. We bought our house a little over a year and a half ago, and it has upstairs laundry. Our dryer, which was bought used off some friends awhile back was really struggling to dry our clothes, especially large loads. We're talking taking two to three 70 minute cycles to dry clothes. So when black Friday came around we went and bought a brand new set. Unfortunately, it didn't seem to give us the drastic drying time increase we were expecting, so then we hired a company to come out and clean the exhaust line and that is when we discovered two things. First, the line was clogged with all sorts of lint from years of use without being cleaned, and second, the dryer line was pushing 40 FEET LONG!! For whatever reason, the idiot builders of the house decided (my guess is they forgot until it was too late) that rather than putting the dryer next to the exterior wall upstairs and having it exhaust a total of 18" out the wall, instead they put it as far away from the wall as you could in the room, and have the exhaust go 90* down, 90* to the right, then 6 feet towards the middle of the house, then 90* again down, drop an entire story to go under the house into the crawl space, 90* bend again and then a 30ft run to the side of the house. Mind you now, that each 90* bend adds about 5-7ft equivalent length to the dyer run. So after the cleaning we still weren't seeing very good drying times, and our brand new dryer was getting very hot to the touch as it tried to dry clothes, and push the hot moist air out the exhaust line. We had tons of wet lint build up inside the dryer to the point that after every load (which typically took two cycles) we would have to wipe down the door from all the small wet lint, and we even had some instances where the moisture would build up so much inside that we would get beads of water rolling down the front of the dryer from the dryer door. This is when I started researching products, and ultimately came to buy the Fantech DBF 110 Dryer booster fan, and absolutely couldn't be happier with that decision!! Install was pretty easy, the hardest part for me, was wiring in a new outlet under my house so that I had the option to unplug this unit when it was time to do preventative maintenance on it vs. having it hard wired 24/7. One negative for my application, was that the really cool feature of the auto on/off sensor (another reason I bought this unit over others) doesn't work for me. The reason being, is that I installed it on the straight run under my house, and there is just too many 90* bends ahead of the unit that cuts down the force from the dryer upstairs and it doesn't have enough pressure to activate the sensor. So I had to simply follow the wiring diagram in the manual and rewire the unit so it just ran 24/7 once plugged in. I then bought a RF switch that I plugged it into so that I now have what looks like a car key remote hanging next to my dryer upstairs, and when we run a load, we push the button on the key fob, and it turns on the fan, and when we're done it we hit the button to turn it off. It works out really well, and we will save the life of the fan a little by not running it all the time. Bottom line this unit is worth every penny, we can now dry large loads of laundry in 40 minutes, and on smaller loads, even less. I would happily recommend this product to others who have similar needs. Total now, I've had this unit in place and running for about a month with no issues.
Review: This fan blew me away - My electric clothes dryer seemed to be taking longer and longer to do the job. I have a duct run of about 18 feet, and despite running a cleaning brush through it a couple of times a year, not much of a gust was coming out the exhaust vent. I thought this fan would help. The fan took about two weeks to arrive. I'd already replaced the entire run of ducting with smooth, metal duct. When I unpacked the fan, I found the housing was severely cracked in two places, even though the shipping box was perfectly intact. I contacted desertcart, who in turn, contacted the seller, Professional Grade Products. They were very courteous and responsive, contacting me within an hour. They sent me a pre-paid shipping label by e-mail for the return, and I dropped off the box at a UPS Store. Within two days, I had a new fan. I was very impressed with how responsive Professional Grade Products was in replacing the item. I've noticed one review commenting about the bracket being flimsy. Though it seemed pretty solid, when I mounted the fan on it, it did sag a little bit. However, sincethe fan unit also sits upon the duct, there was no stability problem at all once installed. The one issue with installation I had was that I'd installed the ductwork more or less flush with the wall, but the mounted fan was about 4 inches further out. I used twistable elbow ducting from HomeDepot to make the connections. Not a big problem. I find the fan very quiet. The dryer itself makes more noise, so the fan seems almost silent. It provides a wonderful flow of air from the dryer to the outside vent, whisking moist, hot air from the dryer, and considerably speeding the drying process. The pressure-activated switch is terrific. A small plastic "sensing" tube from this switch is inserted into the duct just before the fan. Once the dryer is turned on, the air pressure within the duct activates the fan, and it turns on within seconds. After the dryer stops, the fan runs for maybe a minute or less, then turns off. Very nice that there's no separate switch to remember to turn on or off. In my set up the bracket is attached to a cement block wall, and there are rubber grommets between the fan housing and bracket. No vibration whatsoever is evident. It runs quietly and efficiently. I'm making a leap of faith, too, that the increased air flow will pull lint through the duct more effectively, so there will be less buildup - but that remains to be seen. If you're running a long duct, and seeing inefficiencies in the operation of your clothes dryer, this fan just might be the ticket to faster and more efficient operation. I'd recommend it based on my experience. And recommend Professional Grade Products as well, based on their responsive and high quality customer service.

## Questions & Answers

**Q: I'm thinking of buying one but will I still be able to have my duct cleaned after it is installed? I'm the thinking it will be in the way.**
A: Good product -- Recommended.  We purchased this unit to replace the exact same original unit installed by the builder.  We didn't know the blower was in our attic, so the original failed due to neglect after 11 years of service (a long time in my opinion).  We did not install a separate inline filter (such as the Fantech DBLT 4W Lint trap, 4" Duct) because there is no place for us to install one unless we open up the walls and completely redo the duct system.  Instead, I simply remove the unit each winter and use a duct cleaning brush attached to my drill (https://www.amazon.com/Bluesea-Cleaning-Removes-Synthetic-Attachment/dp/B08MC554YH?ref_=ast_sto_dp) to remove lint build up in the lines (you will have some) both up and down from the blower.  I also remove and clean the blower unit which traps lint on both sides of the blower.  After cutting electrical power to the blower at the breaker box (VERY IMPORTANT STEP), I simply remove the unit for maintenance.  The goal is to remove any lint layers that have built up on the blades or walls of the unit.  A set of wooden chopsticks and a shop vac make the job pretty easy.  The overall job is not that difficult, but you will spend time in your attic to get this done, so proper respiration, eye safety, and electrical shock prevention are required.

**Q: I purchased 32 of these for a new apartment building. 10 of them run continuously. Does anyone know how to fix this or are they defective?**
A: From memory, and I'm guessing here ... the switch diaphragm must be mounted vertically.The switch is activated by airflow throw the plastic tube (it's a clear tube on mine) that runs from the bottom of the fan housing up to the electrical components. Take that tube out of the housing and plug it (tape the end). Let it sit that way for 10-15 minutes and see if it still runs.If it still runs and never shuts off, you may have a defective switch.If it stops, your switch is probably good. I believe I remember that moving that tube further in/out of the housing can adjust the sensitivity. Meaning I think if you slide the tube into the housing further, the switch will activate more quickly/easily. If you pull the tube as far as it can go without taking it out completely makes it less sensitive.If you have some continuous source of airflow, obviously, the fan will blow all the time. But I thought the switch was set to stop at 10 minute intervals and never continuously run - not sure - I thought I remember this feature.

**Q: Do you nnee a lint catcher with this? Or will you be fine without it?**
A: The rationale behind 15 ft...
If your vent fan is 15 ft or more from your dryer then the lint coming from the dryer will be dry enough such that it will not stick to the vent fan blades and later create imbalance, increased load, and inefficiency. The lint needs to be fairly dry when it reaches the fan blades. If the fan is within 15 ft of the dryer the lint will still be damp and a lint trap will be needed. Get the fan at least 15 ft away from the dryer and no lint trap is needed.
Note... If you do get a lint trap make sure you measure the dimensions. It may be deeper than your wall you plan to mount it in. If I remember right the lint trap is around 7 inches deep and many walls are not that deep.

**Q: can this be used with gas dryer?**
A: It is activated by the pressure in the exhaust tube and runs on it's own hard wired power supply. I did not see anything on the product description that specifies that it cannot be used with a gas dryer.
