Another amazing teaching moment: NEVER EVER trust any answer about a question like this from ANYONE on TH-cam or a website. So who knows the correct answer? Can you think who that would be? Why of course, the company that *makes the fan and has to back up the warranty*. They've tested the fan, they know when performance drops, they're the ONLY go-to source for the correct answer. Often it's in the installation instructions.
I’ve researched a number of ventilation fans recently and have yet to find this answer on any manufacturer website, installation instructions, etc. It’s been an exhausting search.
It's BAD advice from @DR-um2bv. Read the Fantech Installation manual. Call Fantech. Hit them up on their Twitter/X account or Facebook. There is ALWAYS friction loss from air moving through ducts.
As per Tim's recommendations several years ago, I had 3 FanTechs installed. yes they do work. 360 cfm model in the Master Bath + 190 cfm model in the Powder Room + 270 cfm model in the Guest Bathroom. Yes they are quiet. & yes they exhaust a lot more than any other bathroom fans we have ever had. Highly recommended.
I just installed this fan in my home. Thanks so much Tim for this great video. These fan systems work exactly as you have described in your video. I will not own a different ventilation system from this point moving forward.
That's fantechstic. If I have insulation in my attic and it is hard to reach the fans from inside the attic, is it still possible to upgrade my fans to these?
I've been wanting to switch to one of these systems in my master bath, if Fantech products are good enough for Tim, they're good enough for me. Haven't been steered wrong by an AsktheBuilder video yet.
@@askthebuilder I'm finally gearing up to get a PB270-2, and while I have plenty of room to work in the attic, my planned install location would leave a rather short set of runs (< 4-6 feet) from intakes to the fan, and fan to roof. FanTech recommends in the manual a minimum of 8' duct lengths. Should I move the fan further out into the attic to hit that number or does it really matter?
Regarding turning on the fan: If both bathrooms are switched to it, how do you ensure that there is no conflict with one bathroom turning off while the other needs it on?
Is there a wiring diagram online? I would like to have a full picture of the wiring required before I close the walls and purchase the fan and components.Thanks in advance!@@askthebuilder
These are great fans, I've done several systems like this. The key thing is, with this system for a bathroom, I would recommend installing that inline blower unit where it would be easily accessible. You get so much dust/paper fiber that accumulates in these fans in a short period, it really should be cleaned out every year, or two. This paper fiber dust is from tearing toilet tissue from the roll, a dozen times everyday..
I have 3 bathrooms, all on different levels, leading to an attic exhaust through the roof. Question: I take it i could just install the fan just before the roof exhaust?? Also if someone on level one A turns on the fan, does it also suck from the other two bathrooms as well ?? Which would also mean auto timers, humidifiers would also suck to, from the other two. Is the activation system to multiple bathrooms all copper line or can some or all of it be wireless??
I have a house without central air and the upstairs always gets blazing hot in the summer but the basement is always cool. I want to use two of these setups, one to pull air from the basement into the bedrooms, and another to pull air from the ceilings of the bedrooms back into the basement. Basically circulate the air from the basement into the bedrooms to try to equalize the temperature. Someone suggested these fans. Is there a better option?
Rob, Yes, there's a FAR BETTER option. Your plan *WILL NOT WORK*. This requires one of my phone calls. FAR too much to type: shop.askthebuilder.com/15-minute-phone-or-video-conversation-with-tim/
I have contacted FanTech and have not yet received a reply (I just sent so not expecting one yet but hoping to install tonight). Instructions state a minimum of 8' of flexible duct between grill and fan; but then below that, instructions state to uses the shortest straightest route. My shortest straightest route is about 4-5' and doesn't meet the 8' minimum. Any thoughts?
How do you wire the fan from 2 separate locations? I can’t figure that out for the life of me. 3way switch would work if only 1 bathroom was being used. I hit a wall with the scenario of when both bathrooms are in use.
Simple. Far too much to type for you to be safe. You need to get me on the phone for 15 minutes: shop.askthebuilder.com/15-minute-phone-or-video-conversation-with-tim/ Far cheaper than you calling an electrician.
If you use a time in both bathrooms on the same circuit wired to the fan, either bathroom would turn the fan on until the timers done. The only reason you would need a three way switch is if you want to be able to turn something off from two locations. If it’s on the same circuit you enter bathroom #1, the timer turns on the fan in the attic. Just after someone enters bathroom #2. The fan is already on but that timer sends power to the same fan. But it’s the same circuit so nothing changes. The person leaves bathroom number one and the timer opens and stops sending power but the timer is still closed in bathroom #2 until that timer finishes and opens up.
That's correct. It pulls from all connected inlets. The typical installation is two inlets in one bathroom - an inlet over the shower area and one over the toilet.
@@gillbogillamonster5756 I'm wondering if you read my reply to bluebird5100? Think of how the return-air inlets in a house that has AC work. One fan in the air-handler machine sucks air from all the rooms. Realize you do NOT have to hook up this FanTech fan this way. You can have two separate FanTech fans per bathroom. But if you have two SMALL bathrooms, one larger-capacity FanTech fan will take care of both rooms. You save sweet moola.
If this fan is rated for 110 CFM, and both of the two bathrooms needs 55 CFM or less, sharing this fan between the two seems like a good idea. But if one bathroom needs 70 CFM while the second bathroom needs 40 CFM, it seems that you would need to do something to ensure that the exhaust CFM is split accordingly.
Although I appreciate the information, it would've been even more informative to mention that these setups run b/w $2,000-$3000+ for those on a budget doing some quick research
How in the world did you arrive at those figures? I can purchase the fan, the ducting, and controls for only hundreds of dollars. Look: www.supplyhouse.com/Fantech-FG4-FG-Series-Round-Inline-Exhaust-Fan-4-Duct-100-CFM
How long can you run the duct?

Thanks Tim! Working on installing one of these...do I need to insulate the motor itself? Concerned about condensation.
Contact FanTech - see what they say!
What did you find out ?
That's fantechstic. If I have insulation in my attic and it is hard to reach the fans from inside the attic, is it still possible to upgrade my fans to these?
It is possible. You just have to wade through the insulation enough to run the flexible duct and to make the connections.
I've been wanting to switch to one of these systems in my master bath, if Fantech products are good enough for Tim, they're good enough for me. Haven't been steered wrong by an AsktheBuilder video yet.

Yes, there is a wiring diagram online. Where do you think the best place is to look for it??????????
Does it pull the air from both registers then at the same time? Or is one closed while the other one open?
Same time.

Sounds like you need to do a phone consult with me: shop.askthebuilder.com/15-minute-phone-or-video-conversation-with-tim/
If I have concrete outer walls can this remote fan be installed through concrete? Also can I have rigid ducts instead of flexible ducts?
Yes. You can have whatever ducts you want. Better read the installation manual.
Thank you!! Also can I connect two kitchen exhaust vents to one remote exhaust fan?
HOW MUCH CFM IS THE FAN

Can you put the dryer ducting into one of those?
When you asked the *manufacturer* this question, what was their response??????
How do you wire that?
I used the romex cable called for in the written instructions. You'd do well to read them.
what about a switch to control the led light?
Easy. Nothing to it. Electric 101
@@askthebuilder None of the accessory switches demonstrated control the light?
So if you turn it on, will it pull from everywhere it is connected?
That's correct. It pulls from all connected inlets. The typical installation is two inlets in one bathroom - an inlet over the shower area and one over the toilet.
So in your example with your daughters house, when you turn on the fan for one bathroom you are turning it on for the other bathroom as well?
