User questions & answers

Question:	How long of a wire does the sensor come with
Answer:	The sensor comes with no wire. It works on the existing wire running to the dryer but will also need to be connected to a wired 110/120 volt outlet that the blower motor plugs into which if you dont currently have at the location you mount the blower motor, will need to be done. So you will need to know the distance from either your electrical breaker box to the blower motor (routing past the sensor mounted at the dryer) or if you have an existing 110/120v outlet near the dryer that you can tap into and run to the sensor and then down to the blower motor.
Question:	Installed 6-28-2017; Installed a lint trap right before it. By 3rd load of laundry fan is hot, stops by itself w laundry still running, Defective
Answer:	Mine is 2 yrs old & works perfectly. Also have lint trap above the dryer & clean it after every load. Amazed at how much gets by the primary filter. Maybe your filters are plugged or something is stuck in the fan itself. If not that sounds like it's defective. Wiring OK?
Question:	Will this vent clog with lint? Did you require an electrician to wire
Answer:	I have this installed for about a year now, and not had any lent problems. This came with a plug on it, so all I did was plug it into a power strip and I turn it on every time we run the dryer . Hope this helps
Question:	Does it come with a mounting bracket
Answer:	Yes, mounting bracket is included. It is the silver part next to the cord in the picture.

Tjernlund M-49504351 In-Line Fan with Current Sensor Switch Dryer Duct Booster

If your dryer is not close to an outside wall and the exhaust pipes has to snake throughout the home to vent to the outside your clothes dryer's performance will suffer. The fan within the dryer is only so powerful and adding a dryer booster fan will decrease drying times, especially with heavy loads like towels, blankets, etc.

Also, add this to have the booster fan decrease lint build up (and the risk of dryer fires) by keeping the lint moving at 1200 FPM so it doesn't stick to the vent pipe.

Product description

The Fantech dryer exhaust fans have been specially designed to solve the problems caused by long duct runs on clothes dryers. According to dryer manufacturers and some local building codes, exhaust fans should be added in the dryer duct run when the length of the duct exceeds 35 feet with no bends, 30 feet with one bend or 25 feet with two bends.

• Performance certified by HVI
• Pressure-sensing switch automatically turns on the fan
• LED indicator display panel
• Blower:160 cfm

User questions & answers

Question:	I would need to install this 3 feet away from the dryer, does anyone think this could work
Answer:	The instructions clearly state that you need to install the fan a minimum of 15 equivalent feet away from the dryer but you could place it 8 feet from the dryer but only if you install a secondary lint trap 4 feet from the dryer. The distances change based on the total length of vent pipe but all that information is in the instructions.
Question:	Does the LB2 turn off more consistently than the LB
Answer:	I don't know because I've never used the LB1. Sorry
Question:	What is the difference between lb1 and lb
Answer:	I looked on the Tjernlund website and they do not even list making/selling the LB1 model. I was able to find a spec sheet on it and from what I can tell they are the same. My guess is they changed something (maybe like the motor) and gave it a new model number LB2. I have the LB2 and it works great.
Question:	can i install this unit behind the dryer
Answer:	No. There's a chart that you have to use to calculate the distance from the dryer to the booster based on the total length of the duct work. See this link for installation instructions, the information you need is on page one. http://www.tjernlund.com/Tjernlund_LB2_Dryer_Duct_Booster_8504216.pdf

Features the Lint Blitzer material handling wheel & 5 year no-clog guarantee. 50 watt motor is not exposed to heat, lint or moisture. Includes 115 VAC cord - automatic operation.

Clothes dryers are often installed in areas of homes where they cannot work effectively leading to long drying times, high energy use, and lint buildup in duct work. If a dryer’s exhaust duct run is over 25 equivalent feet* moist air cannot effectively exit the dryer and exhaust to the outside—bogging down the entire drying process.

If a dryer’s exhaust duct run is over 25 equivalent feet and the dryer is experiencing long drying time, your dryer may need a Dryer Duct Booster fan. The Dryer Duct Booster can also reduce the potential fire hazard associated with lint buildup.

User questions & answers

Question:	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
Answer:	It probably will be in the way. My handyman chose to detach it to clean the duct and then reattach it. It wasn't a major job.
Question:	can this be used with gas dryer
Answer:	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. You could always contact Fantech Customer support: Customer Care10048 Industrial BlvdLenexa KS 66215Tel: 800.747.1762Fax: [email protected]
Question:	Do you nnee a lint catcher with this? Or will you be fine without it
Answer:	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.
Question:	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
Answer:	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.

User questions & answers

Question:	Can this be mounted vertically without harm to the motor or bearings? Answers from mfg or installation instructions only please. Thank you
Answer:	I don’t have the installation instructions anymore to reference sorry
Question:	Would this fan properly vent a 1000w hps lamp
Answer:	I am cooling two 600 W HPS lamps with a single fan and it works well
Question:	Can this fan be used to help with drafting on a wood stove? In line at top of chimney
Answer:	If you use it to move air into the stove pipe from an outside source, the fan can be outside with a duct that enters the stove pipe midway. This would act like a venturi to force air upward. Think about adding a 45 degree t to your pipe and using this fane to draw cold air from outside and forcing it upwards in the pipe. You don't waste warm air and you get a really stoked fire.
Question:	Can you hook up a speed control to this booster
Answer:	You can hook up a speed control but it does not work very good and was not designed for one. When you start cutting down the power, the fan struggles and eventually stops leaving a loud humming or buzzing sound which does not sound good for the fan and may pose a fire hazard. If you want a variable controlled fan, just buy a fan that has variable control. I made the mistake of buying variable control with this fan. I ended up buying another fan that I could use this variable control on and it is more powerful and much quieter.

User questions & answers

Question:	If powered from a switched outlet, will it remember the last speed setting or does that require constant power
Answer:	Morning RS, the S4 will not remember your fan speed. It’s a manual setting only. I also have a T4 with a smart controller and it does remember and can be set to auto for heat and humidity. The T4 is for auto exhaust and S4 is intake. If it is your only fan go with the T4. Also, if you have more than 200sf to ventilate go directly to the T6. The are very quiet which is important as my room is under a bedroom. Hope this helps.
Question:	What is the max temp of use for this fan? i see you said 240f, but all other manufacturers with plastic impellers say max temp 140f. are you certain
Answer:	Hello, The Maximum rating for that fan unit is 230 degree Fahrenheit. This is what the fans materials are rated for. Thank you for your question! Kind regards, Andrew Avila AC Infinity
Question:	What is the best way to connect this to 12 or 24 volt system
Answer:	Hi there, Thank you for reaching out to us! I'm sorry but this product would need to be plugged directly into an AC outlet to power on or you can also connect the fan to an existing digital thermal controller from the CLOUDLINE T4 model. We do not recommend hardwiring any of our products as it would deem the product out of warranty and will likely cause damage. Kind regards, Kenny Ngo AC Infinity
Question:	How well does this work with a carbon filter
Answer:	I have a 350 Cfm Coco/Carbon Fiber filter that I place on the Exit side of my application. I have tested the filter on both the intake and the exit. I found these units Push much better than they Pull. I do have to increase the power by 10% when I install the exit filter, but it's not really an issue in my application.

Product description

Decrease drying times and eliminate dangerous lint build up in your dryer system. This Dryer Booster Fan helps boost the performance of clothes dryers by allowing the dryer to more effectively exhaust the moist air created during the drying process. Long or zig-zagging duct runs can hamper the dryer's ability to get rid of the moist air in the drum. This means you are drying your clothes with damp air and if lint that gets past the lint trap isn't properly exhausted completely out of the system it can build up and become a major fire hazard. Includes instructions, hardware packet and mounting bracket.

Question:	Can it be mounted verticaly
Answer:	Yes
Question:	Dryer vent runs from back of dryer along tge floor behind washing machine about 4 ft then straight up 6ft through the ceiling into attic. Can I attan
Answer:	I had a carpenter install a T booster fan in my attic, as my dryer is located on an interior wall, with no access to exterior wall, so carpenter installed exhaust thru roof with big U shaped plastic pipe out. so far, no lint on shingles or problem with dryer overheating. carpenter installed on/off switch and timer switch above my dryer. I can set timer longer than I think it will take to dry load, and fan will cut off. I can turn booster fan off completely if I might think there was a problem with booster fan, but still be able to use the dryer until carpenter came to repair ?
Question:	Does it automatically come on with the dryer
Answer:	No it does not. It needs to be wire to 115vac thru one of three ways. 1) simplest is a on/off switch. But you need to remember to shut it off. 2) thru a timer switch which goes off automatically. 3) thru a current sensor (950-9351 ) this is the best way then DBF2 wiil go on off with dryer. But you definitly need electrician to install & hook it up. Good Luck , Frank

User questions & answers

Question:	Does this fit any dryer
Answer:	No it does not. I went to Walmart and picked up a few.
Question:	Can I Recycle This

Question:	Will this fit in a 4" port on a Milliard 36 x 36 73 grow tent
Answer:	No. I wouldn’t use this. Higher temperature applications require a different flex usually all aluminum for dryer venting because of the moisture levels being exhausted.
