Reduces Drying Time!!

I have a double whammy with my dryer venting. Apparently in 1998 when my house was built someone considered it acceptable and passed inspection to use 3” PVC for my dryer vent which was about 35 equivalent feet from the floor out. I had to use a reducer to get the 4” down to the 3”. Our dryer is gas, and it had always wanted us to check the filter because it was reducing air flow. It was always questionable on how long things would take to dry. I knew two things, first I was going to replace the PVC with 4” duct and second because of the equivalent length I should get a booster fan. After researching, I knew I wanted either the Tjernlund DBF2 or the LB2. For those that have looked the LB2 has the pressure sensor to activate. The DBF2 needs something to switch it on. Both need power available. The LB2 requires running a small cable to provide information on the status of the unit. Looking at the reviews it seemed like quite a few were having issues with the pressure switch. This unit seems like the same thing without the pressure setup for about $150 (current prices) less. Since I was going to have to run wire to the laundry room anyway, I chose to use a switch timer I got her on Amazon and just hit the timer when we start the dryer. It has lights at least showing the timer is active. https://www.amazon.com/gp/product/B0184PH9TM/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 When I went into the crawlspace, I realized that not only did they use PVC but that it wasn’t sloped properly so when cut it open water poured out. No wonder drying time was poor at best. I looked at the instructions for the LB2 and they seemed better for the distance the unit should be from your dryer, so I used them to know my minimum equivalent distance I needed to be. It is installed over halfway of the length. I got it installed and was ready to test. I have only had it for two days so there may be a follow up later. As others have said there is a noise to it, but it isn’t bad. Switched on with the dryer not on and going out to the dryer vent it is blowing well. Going in and running large loads of towels a load that normally would take at least two heavy cycles took less than 39 minutes. How much shorter I don’t know because that is when I checked it. Now the holdup will be washer time not dryer time. Now we get a “Good airflow” light instead of the “Check Filter” Unlike another user that mentioned his dryness sensor reducing the time, since installing this my sensor isn’t accurate. Maybe it is thinking clothes are still damp from the air being pulled out. Any suggestions? Apart from that we are very happy and that isn’t a deal breaker we may just have to go old school and use the timer till we can figure something out.

SIGNIFICANTLY improved electric dryer cycle time

I have the equivalent of 80' dryer duct length because whomever built my house decided to cross the entire house to exit the dryer duct. As you can see my ducts were severely occluded from 20 years of lint buildup to the point of severe fire danger. I installed the Tjernlund DBF2 because I could boost the air flow across this length of duct without risking lint buildup in the booster fan. I also chose this model because I could direct wire it to a smart outlet. I also wired my dryer to a power meter so when I turn on the dryer, the DBF2 automatically turns on via a rule in Hubitat Home Automation system. My wife doesn't have to remember to turn a timer dial or turn it on or off, it automatically runs when the dryer is drawing power. Genius. I did this method over the other Tjernlud product because the negative reviews had issues with the air pressure on/off sensor. I didn't want to mess with a product that didn't work. How well does it work? With my dryer set to auto-sense dryness, the booster fan pulls enough airflow that the dryer stops running around 27 minutes on a 40 minute cycle time. I'm saving 13 minutes on my dryer time! Compare this with before I installed the DBF2 when I was running the dryer 2 or 3 times before my clothes were getting dry! How loud is it? The booster fan is audible, but it's not really loud. It has a hum but it's not distracting. I stuffed the thing up between my floor joists so I can hear it in the upstairs room. BUT I can barely hear it over the sound of the dryer and I my wife has a habit of running the dryer when we go to bed, and I have no problems going to sleep with the dryer on and duct fan running. If you have a long duct run I would recommend this product. I have not yet pulled the duct down to evaluate after 1 month if I'm getting any buildup in the duct work, but so far, so great.

Decent Product Just installed

I purchased this model over the others simply because of its design with offset inlet and outlet so the lint does not block the passages. Overall the design and build quality is very good. It is made well. The bracket is strong and holds the booster fan in place. I added rubber gasket to the bracket mount to isolate any vibration. I also bought the current sensor (that was advertised with this fan. But it failed on the first try and kept the booster fan running. So I added a 15amp 120 VAC on/off switch to it for now. The supplied installation instructions were very clear and with wiring diagrams for various application. I have only tested it for a short time so I plan on providing a full review in a month or so. It is quite fan and does not vibrate at all. Works fine for now. Down the road i plan on installing a lint trap since this company's lint trap is expensive. 4 stars only because I have not run it for a longer period of time. Hope this helps you all.

Good booster for gas dryer...

Gas dryer is the middle of the house in the garage. Estimated the vent pipe over 35' including (20'=5' x 4 elbows 90 degrees) so I need a good booster. After extensive search, I got this product that has no power cord. I use my old computer power code and cut the one end to strip the three wires to connect fan motor. Next I figure out how to mount and wire connection. I bought the remote wireless power control and testing it is working fine now. The mount kits is not strong enough to hold the a little heavy unit. I add some support with metal strip abound the frame. I feel it is more strong to support it. Later I will connect all pipes that is easy to do that.

About as sexy as a dryer vent can be

Installed in hours, coupled with the current sensing switch means it’s incredibly easy to use. Squeaks a little as the lint blitzer comes to a stop, but a little celebratory cry is justified after every performance. Quicker dryer times and quiet operation make this a no brainer when installing a dryer run that looks like a rat maze. In short this thing really sucks… or blows depending on this you look at it. If you’re looking for dryer vent booster fans this one is sure to impress all the your diy dad friends.
