Can these fans be used for radon mitigation? Are they quiet? Can I use a variable speed switch instead of the humidistat?

I'm sure it would work to remediate radon but you would have to retest just to make sure. To use a variable speed switch you would have to call an electrician and yes it's very quiet.

Ventilation in general helps radon. They are relatively quite being in the basement you cannot hear it. About as loud a desk fan. I'm not sure on the switch or why you'd want to. The humidistat urns fan off when it reaches your setting

Hi Mary: I have only used the vent fan to remove damp air from a crawl space. The fan is quiet and worked well for my purpose. You would be better off consulting the mfg or an electrician on the variable speed issue. Some motors can be damaged if run at to low a speed, due to heat build up I think. I would see no need to try and reduce the speed of such a small motor. It is not like it is a 20" exhaust fan moving many cubic or air per minute.I would ask a professional about how to handle Radon and do some online research for information. I know very little about that issue. Good luck. Hi Mary: I have only used the vent fan to remove damp air from a crawl space. The fan is quiet and worked well for my purpose.

First the are very quiet. You can barely hear them. They move so little air I see no reason to use a variable speed switch and would recommend against it. As for the radon mitigation Because this is a life safety issue and can be very complicated, leave the design to profishnels. The gas is typically vented to a safe location and simply venting it to the outside is not advised.

That's a tough call with the supplied information. If the room is going to be used for a single purpose...how much light and would you be supplying the air from outside to the room than outside? Ultimately get as much fan as you can afford (think long term) and a GOOD speed controller. You can always turn it down but you can only go so fast. My fan came as a 440cfm. Don't forget ducting and band straps. I hope this helps

Yes. I would consider a different fan for most applications. My self I would probably get a computer case fan as they are made to run for hours on end and are cheaper even if you buy a power supply to run them. The Broan fans are supposed to run for shorter periods of time and obviously are good for moist conditions.

You can most likely find the answer on their website. These squirrel cage fans work so well on many utility problems, as well as personal cooling, I never thought to look it up. I rarely run my fans above low speed. For drying floors, dispersing air spray and distributing ac air in the heat of summer, they work wonders.

You're asking two questions Dimitri. They will move more air than your stock H80 fans, but if you run them at full speed all the time, which is recommended, then quiet is not going to happen. They are not loud, but you know they are on all the time. These took 6C off the stock fans on my H60, so they definitely made a difference. I am more concerned about having my 8350 CPU being cool. I can live with the hum of the fans.

They are too loud for my taste at 12v. One by itself isn't too bad, but I have 11 fans on 3 radiators (Two 480s & one 360) and they are very loud. I had to get a fan controller to find the right balance between performance and noise. They do move a ton of air, but are very loud to me. I can't imagine how loud the non quiet edition ones are. I have tried so many fans over the years and a truly quiet fan that can still push enough air through a radiator just doesn't exist yet.

No. The current and resistance is non-linear and the fan requires full voltage. The type of control you would need is one that does not provide variable resistance but rather a temperature activated relay for full "on" and full "off" as temperature changes.

I've always used slow 120mm fans with this cooler. It is still virtually silent, but gives you a little more cooling. I use metal wire ties (the kind used to hold loaves of bread closed) to hold fans in place.

My radon reduction system, powered by this fan, is 14' by 28'. It was a decision made by the experts, but I trust that they installed a fan to fit the need.

These fans have A/C motors with multiple windings designed to operate at preset voltages. That's why there is the switch. You can damage the fan, or overheat the "dimmer", the latter which could result in a fire. Don't do it!

The fan mode is controlled by flipping the wall switch. If you want a faster speed flip the switch again. It is a very quiet fan, so wait a minute for it to get up to high speed. The humidity control is the best feature of this fan, turning it on and off automatically depending on the amount of humidity in the bathroom, the purpose of the fan. As far as I know one switch control one fan since its a multi mode switch. Hope this helps

Do bear in mind that the rated 52 CFM is at the best possible scenario, where nothing is blocking the fan in front and/or behind it. Once you have a filter, it'll reduce that 52 CFM. Also, in my opinion, I don't think these fans are overly quiet.

I have had this installed for 6 months now. It is typically used with a variable speed control in place of an on/off switch. It is an industrial strength fan. When it is running at full speed it is moving a lot of air, making it necessary to raise your voice a bit to talk over the noise. But it really airs out the room in a hurry. At low speeds, it is much quieter. The air noise is just a whisper, but there is still a noticeable hum from the motor.

It's a horrible idea to use this fan to get air into a room to be honest. This is simply a computer fan, and the dust and dirt it will pull it from outside will ruin itself. Its also just 120mm, perfect in a computer situation but not for a house... Yes, in theory your configuration would work though.

Definitely not. I wouldn't use it even in a protected area where subject to either temperature changes or humidity changes of any extent. Strictly an inside fan.

The Honeywell C060 has a high volume fan it moves over 1500cft/min. Even at low speeds, it can move more air than your average house fan. I know of no way to reduce the air movement without changing the fan. But if you do that, you've lost the efficiency, and defeated the purpose, of the C060. Good luck.

The effectiveness will be marginal. I've used one in conjunction with a pedestal fan when painting my basement, which doesn't have any opening windows. I use the radon fan with 4" rigid duct through a dryer vent opening. I think it helps for ventilation, but being able to open a window would work a lot better.
