Why does this say 4000 CFM in one place and 3000 CFM in another?

Might be a typo,seller didn't answer my question about that.but they work great!

Don't no the answer to the cfm question, but I run my air compressor at 100psi.

Not sure about CFM but it's slow I've had several types and they we're all about the same.

It lists as 12.5 but I have since put an additional 45 CFM computer fan next to it and the Valterra fan blows almost 3 times as hard as the comp fan. I think they got the measurement wrong.

from box of 1f56n-444. a=electric heat terminal b=energized in heating o=energized in cooling g=blower/fan y=compressor w=furnace rh=power(heating) rc=power(cooling) jumper between rh and rc is removed for some applications

Three settings, "High" moves a lot of air. I'm not sure how many cubic feet per second, though. May be in technical specs.

The manual does not mention it either. I would Google around for general information on the subject. That said, I have a 1700 sq. ft. home with the EDV-4000 located in the central hallway. It keeps the whole house at a comfortable RH level, which then allows us to feel more comfortable using less air conditioning/cooling.

Not sure about code but go with the 80 cfm model .Have the 50 cfm in our 6 x 8' bath and it is slow to exhaust the room

I compared specs of this against the newer FFRS1222Q1 and the only difference seems to be the CFM (cubic feet per minute) airflow rate at highest speed, being 500 on this one and 339 on the new one. Additionally this one claims to cool 640 sq ft, while newer one is just 550 sq ft, probably a result of a lower fan speed. Not sure why they would make a new model just to lower fan speed. Maybe it's quieter, but there's nothing in the specs for that.

the CFM rating on these is generally part of the model number, in this case it is 240 cfm.

Wondering those specs myself and I found this on another website:CFM/AMP Information:Inline Fan 4" - 171 CFM / 1 AMPInline Fan 6" - 435 CFM / 1 AMPInline Fan 8" - 745 CFM / 1.7 AMPSInline Fan 10" - 780 CFM / 2.1 AMPSInline Fan 12" - 1060 CFM / 2.5 AMPS

Hello, I hope this will help answer your question: My research prior to purchasing the Ventech 4"x12" 210 CFM Carbon filter I was able to contact a Ven Tech distributor who explained that the '210' is the CFM Maximum rating of the filter and any flow greater than 210 would be reduced according to a graduated scale up to the point of an absolute CFM (that rep never said what that was) and at that point would make sense to purchase a larger filter or one with a higher rated CFM. The good news is, that any thing below 210 CFM would not be impeded. In my case I had purchased the VenTech IF4 4" Inline Duct Fan 190 CFM, and at 190 CFM according to the representative I would experience no reduction. Now if your research uncovers contrasting information, let me know. Cheers!

According to the manufacturer, (L) 384 CFM (M) 434 CFM (H) 460 CFM (cubic feet per minute).

Its meant for contoling a living space. Not sure its intended for non livinbg space (eg 140F). The documentration claims a 1 degree differential. Wrong! My observation is more like 3-4'C ( about 10'F)

Hard to get that information i guess the cfm should be a big number because i have never used it above speed 1. Huge amount of air... Very impressive.

No that is not normal. Jumps to 1500ppm would only be possible with co2 being released near it. It should be around 400ppm outside and 550 ppm inside. Those numbers should be steady. Drastic fluctuating changes would have to be a malfunctioning device.

Sorry, probably should of stated that the amps of the fan should match the amps of the switch. Oh the fan you r looking at has a temp control unit that has to be removed in case you did not know and if you want good suction u might want to go with the next size up the more cfm even the 2500 one kinda wish I got the better one
