Do you have a stronger fan, similar to this one but able to move more air in or out?...this would go into an underground bunker...

Not at this time. This fan currently is the only one we offer in this vent unit.

Yes, it works quite well for that. It uses a motor that's not open, and won't cause any problems with the fumes. That's one of the reasons I like it. There isn't a fan on the market for that price that moves more air. To move that much air sometimes you'll probably want to make sure you've got the shop vented to provide intake air so it can move enough of it. Hope that helps you out! Fletch

Cody.. Which fan did you end up purchasing. Doing the same thing. Current fan I am using is not powerful enough.

We are using ours to exhaust air from inside the crawl space to the outside. I don't believe it is intended to work the other way around.

Yes i have one going into my tent with 8 in duct for frsh air. And one attached to my two 600watt hps hoods pulling hot air out. Great fans my have been running for over a year straight with no noises. Every 3 months pull apart and dust it. I recommend using a reducer on the end of ur hood thats sucking air. It creates higher flow rates cetered over your bulbs. Make sure to use ladies leggings over the reducer abd over your intake fan to keep dust out of the tent and off ur bulbs. Gl brotha hope i helped.. toke on

I wouldn't. The fan is very weak and probably wouldn't put out enough air for what you're trying to do.

It would work great if mounted in the attic and ducted, might be a little noisy otherwise as it moves a lot of air.

It would move air, but what is your intent? If you use it as an exhaust fan you would have to move air from someplace else in the room (open window). If used as an intact fan, then it would make a positive pressure environment if no outside vent/window/door is open.

I would say it's possible but that's not really what it's designed for. It's used to blow dust out of jewellery and smaller spaces. The stream of air is decent but not enough for a fan. You should just get a can of compressed air like the kind you use to blow dust out of a computer. That would work much better

For the size of the fan it move a lot of air. Installed 2 on my patio instead of 1 large fan giving better area air movement control. I would install these fans again.

It is an exhaust fan connected to a series of below-surface PVC pipes with holes. The suction and ducting provides a way for radon gas to excape into the atmosphere, as I understand it. I see no reason why it could not be used as a simple exhaust fan, but I am not expert. I can say that there is a considerable constant negative pressure due to the tightness of the ducting system, a negative pressure that would be absent if simply used to ventilate a room.

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.

The fan is quite strong. There is also an accordion hose for both the exhaust and the cool air. Depending upon how far apart your two employees are, you could put a splitter on the cool air and give each some air. It should be adequate especially if you had the outlet overhead so the cold air "falls" on them. You also might do better by replacing the accordion tube with a smooth sided duct to reduce drag on the air.

Yes you can. Best and most powerful fan I have ever owned or even seen or heard of. When and if this thing dies I will order another one, no question.

You could do it, its about the size of a map, but its wedged shaped, so that your hands are on a slight incline. You may have to change your position, but I recommend this fan. :)

Yes, this fan will be letting in air all of the time. If you have access inside, and you can reach it, you can shut it off for the winter, and stuff some insulation up into it. But, unfinished attics are meant to have airflow all year long, for proper ventilation, even in cold weather. If your insulation is weak, why not increase that amount in your attic. If you get this fan, it will even work on cloudy days, maybe, not as fast as sunny ones, but it keeps the attic air moving, during the daylight hours. At night, air still flows through the fan , just like a vent openig. I hope this will help ypu. Yes, this fan will be letting in air all of the time.

It certainly moves a volume of air, but you'd have to fabricate a fitting over the output opening and route it up to your opening that you plan on exhausting the air. I think you'd be better off with buying an actual attic exhaust fan.
