How muc CFM does it take to activate? I need someting to put on a case that will have about 100 CFM of air moving with fan running.

Honestly do not lknow, however most bathroom exhaust fans are not even rated for 100 cfm...so I would think it would work.

i'm not sure of the minimum air volume to activate but i am sure that 100 cfm would be able to work the flappers.

My answer is NOT scientific, however the doors open just by blowing on them, so I imagine, especially for your use, there is no better damper.

you will need atleast 240cfm to pull it out of a 8x4 area at 1 interval per minute. I would go with a 400 cfm duct fan.

Forgot to mention, the case fan is quite loud so I would either replace it with a quiet one or get a simple fan speed controller. This is what i got.

Sorry about that I miss under stood the question. But as for the CFM of our machine I don't have the answer for you. I have been selling this machine for 6 months with some of the best results in sale in many years but the company has never had the unit tested for CFM. But the company told me they will try and find out from the actual motor manufacturer who make the motor for the air purifier. But as you know it is not that important for CFM's as it is for regular air flow in your home or office. There is no way a little fan in a air purifier could ever cover a whole house with air circulation . Ionization and air flow is how this unit works. Like when you burn toast in your home you can smell the burnt toast through your whole house.

It works for me with a Can Max Fan Mixed Flow Inline Fan, 6-Inch 334 Cubic Feet Per Minute fan #340410. The speed is adjustable and the noise isn't to bad compared to the flow it gives. I have left it on all the time to circulate air and equalize the temperature in the that room compared to the remainder of the house.

No. To small and low cfm.You will need a 16 to 18 inch fan that flows at least 4000cfm,or a dual fan setup.

Of course it depends on the fan setting, but I have noticed walking toward the fan from 15-20 feet away there is air movement on the medium speed setting

I don't know as I do not have a way to measure. It isn't very strong. I have a dish receiver with a slingox and it gets really hot. This little fan moves air (not a lot) but the bit that it moves seems to help a lot. The nice thing about this fan is that it is quiet. I don't hear it over the equipment. So, it my mind it works great for what I am doing. It states it is 45 CFM. 45 CFM seems like a lot to me and I don't know if that is true. But it is working for my application.

Neither, no air is drawn from or pushed outside of the case, this guy just pulls air thought the fans forcing air on a GPU or similar or card. It does work but it is not the most quiet.

I have two of the double fans (total of four fans) mounted at the top of a closed closet (3ft wide, 7 ft tall) which houses our computer servers and security system hardware. I reversed the mounting on the fans so they are exhaust, blowing the air out of the closet. There is about a 1 to 1 1/2 inch gap at the bottom of the doors where air can be drawn in. The idea is hot air rises and is exhausted while cooler air is pulled in at the bottom. This seems to be working quite well over the past month or so since the install.

Inside the fan it has two switches one you turn for cfm in low speed if you want to use it all the time and when it detects motion go to high cfm for given time then go back to low cfm the wall switch is just a override for the fan to turn it off completely you can go to Panasonic s web sit and put in the model number and get the pdf of the installation manual it has another way to wire it in to and the materials you will need to install it. If you are replacing a old fan you might need to get bigger exhaust piping to move the max cfm I think when I put in i had 4in and I had to put in 5 in. If you don't .size piping correctly you will have ..higher back pressure and can damage the motor over time.

You should beable too, a fan is a fan. And you would want it to blow outwards so he back with sticker facing out.. depending on your mb it should automatically know

I have the dual fans (4000 cfm) ... using to cool a 355 SBC they are quality units, work fine, however, they draw a lot of juice and are noise. I had to go to a 140 amp. alternator to carry the load. I'm going to put seperate switches so I can run 1 fan on cool days and 2 only when needed to drop the load and noise. engine mounted in a '74 260Z roadster conversion with tight engine bay so cooling, even with an alum. rad. and ceramic coated headers a task. Fans did the trick.

The fan will pull out very little running for an hour. If used to push in non-humid fresh air it would in a short time.

the fan operates at 200cfm at high speed with a mouth of 4"diameter. You may use any filter but suction may reduce on type. This is a trial and error depending on your need.
