User questions & answers

Question:	How loud is the fan
Answer:	Equal to a bath fan
Question:	Has anybody used this dryer booster with a gas dryer? I just bought this dryer and it has a CRITICAL WARNING in bold to use only with electric dryer
Answer:	All I can say is there is a reason they say ELECTRIC only.... that being said if you can install it as far as possible from the dryer... ie: where the vent goes out the roof... it would most likely not be a problem... but the device is NOT Intrinsically Safe so using it on a gas Dryer could be an issue. I have one on my Electric Dryer and it solved the issue with a long vent pipe run causing the dryer heat coil to shut down due to overheating...
Question:	My whole vent is done in 3" pvc. Could I put a 3" to 4" reducer on either side of this unit
Answer:	You can do that but it will reduce the air movement. They do make a 3 inch model, I would locate that model.
Question:	what is the air flow rate of this dryer booster
Answer:	The product description is 200 cfm fan....that is the air flow. I would suggest the buyer search the manufacturer's site for product installation instructions to get verify if the unit work in the particular situation. Ex: min or max distance from the dryer for the booster location, and airflow compared to the output of the dryer.

User questions & answers

Question:	Can this be turned on manually
Answer:	No. It has a pressure switch that turns it on and off.
Question:	I installed the fan, and now it runs non stop. I tried a couple of things with sensor hose placement and it still just runs. Any ideas
Answer:	The fan does run much longer than you might anticipate, but it should shut off eventually. I have no installation tips or other ideas. It did work well for us, despite the long-running fan.
Question:	Can this be installed horizontally? We just put our washer/dryer in the garage and need to run the hose from the dryer 15 feet to the wall
Answer:	I installed mine about 10 feet from dryer. Horizontally. The vent continued on another 12 feet. Works great as long as you keep your lint filter very clean.
Question:	Can I use this right next to my dryer or does it have to be 15ft away
Answer:	Uuuuugly! This question appears to have come from one that doesn't want to get into a wall or attic. Will it work, I guess, will it do what it was intended right out of the dryer no, or not as well if manufacturers instructions were obeyed.

User questions & answers

Question:	Can I adjust the fan with a dimming switch
Answer:	No. This fan spins at a fixed RPM based on the AC cycle frequency. There is no adjustment.
Question:	Can i use 2 of this fan on the same line with distance from each other? will it double the suction to 200cfm
Answer:	I couldn't tell the difference with two. And that was their 8" duct fans used to help pull air from an 8" Hyper Fan that was connected to an 8" carbon filter. When I put one duct fan at the end of the ducting(about 15-20 ft length from Hyper Fan), airflow increased significantly. Best duct fans for the price range! Quiet compared to others I've used.
Question:	Am i able to to use this as a carbon filter fan(as in only use this fan for smell) in a 2x2x4(feet) grow tent
Answer:	this fan would work better for the inlet air for your tent. Look up the ipower 190 or 200 cfm fan that could have a carbon filter in either end and that allows you also to put the filter in the tent or outside. If you need to you can use two 4 inch for inlets. these are quiet and dependable and will help control humidity levels and leave clean air going out
Question:	Is this available with a solar powered option
Answer:	No

User questions & answers

Question:	Does this work good to keep the stink away? I got a 2x4 tent
Answer:	5000K is a pretty pure white. They call it a daylight.
Question:	My carbon scrubber stops working every three weeks or so. I have to take the carbon filter off the fan and spray it with a hose really well. Why
Answer:	Thank you for inquiring. Model # OM200/850/LED is an E26 or Standard Base which is the common base type.
Question:	How many cfm is the carbon filter
Answer:	Item# OM300/830/LED can be used outdoors as long as the bulb is protected from the elements and does not get rained/snowed on directly. A fixture with a protected cover that has an open bottom should be okay. Make sure to check your fixtures maximum wattage and do not exceed.
Question:	Do I also need an inline fan for a small tent
Answer:	I haven't used these bulbs in a enclosed fixture and the product description doesn't address this. It's true that the base of the bulb does get pretty warm. it doesn't get very hot. In any case, you can be sure it operates at lower temperature than an equally bright non-LED bulb. Besides, an incandescent bulb would never emit the bright white light of this bulb.

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.

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.

About Us

Fantech does much more than make fans. We are committed to making products that support healthy and comfortable indoor environments.

Our high-efficiency products ensure your loved ones breathe fresh, clean air from this moment to the next.

Because at Fantech, we're not just building fans, we're building solutions and opportunities for a healthier, safer tomorrow.

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.

User questions & answers

Question:	Is this product UL 705 listed or have other certification
Answer:	Yes , This product meets UL705 DEDPV requirements. and complies with International Residential Code requirements and is made in USA.
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

The inception of Tjernlund Products dates back to 1938 and since then, the company has evolved into one of the biggest providers of gas fired furnaces and custom packaged roof top heating & cooling equipment. The portfolio is rich with many landmark products. During the mid-50s, Auto Draft Inducers were developed to eliminate draft problems associated with short stacks on roof top units.

Other people within the heating industry soon saw the advantages of Tjernlund draft inducers and wholesale distribution of the Auto Draft Inducers began in 1957. Tjernlund Products was established as a separate company in 1973. The original manufacturing facility had 12 employees but today, the facility has expanded to 75,000 ft2 and Tjernlund has grown to over 50 employees.

The engineering and manufacturing departments feature the latest technology in 3D CAD design and CNC turret presses and brakes. Tjernlund Products is still largely, family owned and managed.

Product description

Inline Duct Fan

A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms exhaust projects, and cool AV closets. Features an inline speed controller utilizing PWM-technology. Contains a mixed-flow design and an EC-motor for a quiet and high static-pressure performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one duct fan unit, one corded speed controller, installation manual, and all necessary mounting hardware.

Precise Speed Controller

The inline speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. Unlike common AC-powered duct fans that suppresses voltage to control fan speeds, this duct fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation). This technology enables the fan's motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers. Eight-speed options are available with power on/off switch. Due to its backup memory capability, the fan can be triggered to run at customizable speeds when given power. This S8 model can be connected to the smart controller of the CLOUDLINE T8 to share the same programming.

Quiet and Energy Efficient Design

The inline fan features a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids, and performs well even in harsh environments.

• Designed to ventilate hydroponic grow rooms, transfer heating/cooling, circulate air, cool AV closets, exhaust odors.
• Features an 8-speed manual controller utilizing PWM. See T-Series for temperature and humidity controls.

User questions & answers

Question:	Can this fan be used as an inline blower for ventilating a blowerless kitchen range hood? i.e. is it rated for exhausting steam and grease
Answer:	http://www.nutone.com/products/product/e3544720-ea29-4072-bc08-35a03d8636e5 Is the Manufacturers Web Page for this model. Dimensions :Housing:14-5/8" x 7-7/8" x 5-5/8".Grille:9-7/8" x 16-1/4" x 1-3/4".I hope this helpsDave
Question:	Would this be used in a cigar room in conjunction with a air purifier? Looking to build a cigar lounge in my house
Answer:	We have a large master bath, about 10 x 12, and it does well in here as a supplement to our heat pump (we keep the rest of the house around 62 degrees in the winter). It takes it about 10 minutes to get it up to about 68. Ventilation is no problem, it works very rapidly in a bath this size.
Question:	What happens if power goes out? Does it kick back on to same speed settings? How long would it hold thise settings with power out
Answer:	It has to be a typo as the cover assembly on my unit measures approximately 10" X 15"
Question:	We purchased the fan it is only 2 months old. Why does it turn off constantly even as the light remains on
Answer:	Yes.It has 3 completely separate circuits: One for the light, one for the exhaust fan, and one for the heater and heater fan

A Quieter and Smarter Inline Fan

The new CLOUDLINE series contains a cutting-edge Electronically Commutated (EC) motor, controlled using precise electronic pulses and smart programming. This enables the inline fan to operate considerably quieter, and reach low speeds without generating noise or heat. The EC motor is also twice as energy efficient and can save up to 40% in energy costs, paying for itself in the long run.

Smart Programming

T-series models include a programmable controller with precise temperature and humidity sensors located on the 12-foot corded probe.

Quiet PWM Motor

Each fan uses a quiet, energy-efficient EC motor controlled using Pulse Width Modulation (PWM). Dual ball bearings allow for omnidirectional mounting.

Mixed-Flow Design

Featuring a mixed flow design, the fans maintain peak performance in high static pressure environments. Ingress-protected against dust and liquids.

Plug and Play

The complete kit includes the inline fan unit, controller, user manual, and everything needed to mount the fan and power it through an outlet.

CLOUDLINE 4-Series

A CLOUDLINE T4 plus CLOUDLINE S4 system can be linked to the same smart controller, and used in conjunction for a total of 410 CFM airflow. This set-up is ideal for ventilating smaller grow tents and cooling AV rack cabinets.

CLOUDLINE 6-Series

A CLOUDLINE T6 plus CLOUDLINE S6 system can be linked to the same smart controller, and used in conjunction for a total of 804 CFM airflow. This set-up is ideal for large grow tents, AV closet cooling, and boosting airflow for HVAC projects.

MIX and MATCH

The same controller can connect CLOUDLINE fans of different sizes, to share the same programming. For example, an exhausting CLOUDLINE T6 with a filter can share the same controller as an intaking CLOUDLINE S4, to balance static pressure.
