Installed 2 fans in my crawl space to reduce humidity. Still 95%! Should I close off all other vents to keep from sucking in more humid air?

This is much more of a construction question. There are a lot of reasons for excessive moisture in the crawl space. A moisture source, temperature, insulation, air flow, all have an effect on the crawl space. If increasing the airflow did not help I would suggest contacting a building contractor in your area to inspect and make suggestions how to solve your problem.

Gary, My concern would be having the fan exposed to moisture. If you live in a dry area this may not be a problem. I live in Florida so it probably is not a good idea here. Mine is installed in my living room.

I don't have my setup to empty into a drain but the unit I have does shut off completely when the desired humidity level is reached. I have been unhappy about this since the unit is not supposed to shut off completely (unless the water tank is full). I returned one unit after confirming with the manufacturer that indeed the fan should continue running even when the compressor stops (once humidity level is reached). The second unit they sent me is doing the same thing as the first - shutting off and then clicking back on....which wakes me up at night.

no, to prevent the humidity, you could open window or let the door open to make sure the room is vented properly. I sometime put a glass of water in front of the heater to have the moisture in the room

I use three of them in addition to the humidifier that came with my humidor. I try to obtain 70% humidity..... With that being said, I was given a larger humidor recently. The humidifier that came with it plus the three drymistat humidifiers would only raise the humidity to 62%. So, I ordered yesterday this in hopes it will help raise the humidity..... http://www.amazon.com/gp/product/B000PUWHJC/ref=oh_aui_detailpage_o00_s02?ie=UTF8&psc=1 Good luck!

Hi Bob. I bought two fans. This one from Home Depot and another one Air King BFQ 50 CFm from Amazon. Both are running really nice. But they dont have a delay timer or humidity sensor. They both shutdown and turn on by flipping the switch, but to compensate it I bought two Dew Stop, Humidity Sensing Fan Switches Model: FS-100-W2 from home depot. This switch has delay timer for 30 min and humidity sensor. He completely control humid in my both bathrooms. Good thing about those fans they are real quite that my kids can not notice with close door than they are running.

You should turn the humidity setting down using the arrow keys. I set my @ 30%.

That is exactly what I bought this for! Set it in the room and make sure the sensor is located away from the direction of the vapor. It may require more than one fill of water. I run the cord outside of the door to the room and carefully close the door on the cord. I have a humidity meter which I keep in the room. My company actually sells these if you are interested. (www.mbhes.com) I check the humidity from time to time to see when I need to add more. I try to keep the humidity level above 60%. My cellar is about 60 sq feet so this is not difficult and certainly way cheaper than an automatic system- That is exactly what I bought this for!

Our house is 2400sq., one floor. Unfortunately, the control for level of humidity is on the furnace in our "crawl space" and NOT in the house, Therefore, we can never adjust it! Just installed this fall, then we left for our FL house so haven't had the experience. Because of the control location, we would have never purchased it. Amazon site DID NOT explain that!

My first suggestion would be to go with one of their more powerful models, but if you don't want to spend more, I would say that this will bring it down a few notches, but the larger the space, the more dilute it's effects will be. It will still pull the moisture out, but it may not be powerful enough to bring it down more than a few %. And it's also going to depend on air circulation. If the air doesn't circulate, it will bring it down in the area where it's located, but not in the entire space.

If the setting dials are working? The air humidity should trigger your fan....if not you may seek a replacement unit....Thank you..11/23/2013

I had to go with liquid cooling. . . . . as the previous user stated, they fit snug under a traditional fan. But it was enough to make ME worry. Do yourself a favor. . . . go with liquid cooling as well.

It depends on the humidity you're at, and the humidity you're trying to get. I have a 2100 square foot house with high ceilings, and it makes a difference, but I'm also only doing like a 35% humidity in the winter... and I'm not really sure I ever get to 35% humidity, I just know it's definitely doing work.I would really recommend something bigger, as your house heater would likely allow for something bigger anyway. However, having one or two of these installed isn't a waste of time.

I have it in a 10 by 12 foot room and it seems to keep the humidity to 51%. It seems unable to get the humidity below 50%. A small compressor type dehumidifier was able to drop the humidity to below 40% easily. Also, this unit will raise the room temperature more than a compressor type unit will. It is pretty expensive for not much capacity, I will see how long the unit lasts.

If you have not adjusted the Humidity setting to a higher percentage, the fan will continue to run. I had to set my fan to around 80% before the fan would stop running continuously. The actual humidity setting you select will depend on where you live and the ambient average humidity for that area. You should plan to go beyond the average ambient humidity to prevent the fan from continuously running as the humidity levels fluctuate day-to-day.

These centrifugal fans are not designed to eliminate water vapors. For excessive water build up in crawl spaces I would install a small de-humidifier

I had an issue with this drawing in warm humid air from the outside into a 60 degree crawlspace and having that warm humid air condensate in the crawl space making everything drip. I had to shut it off.
