Most glovebox teks all have the same thing, they all filter the air before it goes thru the fan. This slows the fan down considerably, thus reducing positive pressure, or whatever you are using your fan for. This filter can be assembeled
in two different ways. The first, you can rig it so that the air goes thru a coffe filter then polyfil or reverse it for better fan efficency. I prefer it reversed.
Blowing thu fan/polyfil/coffee filter/clean enviroment. The strainer that comes inside the damp rid container proves very useful in the whole process. I lined mine w/ the coffee filter and then added some polyfil for extra protection.

this is the end that goes into the clean area.

The intake is the top of the container. If you want to build one, the pics are pretty self explainatory.

ok, i see now. this is for a positive pressure glovebox, a pre-filter to enclose the fan, correct ?

yea, you mount it on your glovebox, terrarium, or whatever. I remember somone worried about the fan they had mounted to their terrarium shorting out or a possible fire hazard, due to the humidity, this would help in such a situation. But do you know what I mean about the reduced fan pressure?
How Nan, modified the 9ner glovebox, and added a second fan for more positive pressure. Well I think you may be able to get by w/one and have still have enough +pressure. I will post some pics of my glovebox, so people can get a better idea of how this works, its hard to explain...

sure, been there.
i added a second fan, too, on my earlier glovebox as you did.
some pics would be great, that really helps everyone, esp. new ones, in building their own.

You can check out my glovebox at Nan's Nook, until I can post it here. I cant post the link cause its in general and you have to be a member to see general posts.

I opted to use the fans the other way.
glovebox

glovebox
gloves are made from trashbags sealed, and heavy chemical gloves. The trashbags were wrapped around the arms leaving room to feel comfortable, then taped.
glovebox
The container hole above the fan is for transfering small items without opening the door. When not in use it is filled with polyfil and coffee filters.
glovebox
The fans were not sealed with anything but good ole duct tape. Cut your hole big enough to just barely squeeze in the fan/filter, then tape it up to make a seal.
Several people have said that this glovebox probably has enough + pressure to do without the gloves. Cut your armholes just a little larger than the forearm and hang a lysol covered rag over the holes while your hands are not inside the box.

Here is an outside view of the air filter and transfer hole. The Trans hole is great cause you always forget something that was supposed to be in the box right in the middle of your work. Very handy.

you know, i was looking at your transfer hole thing there and i got to thinking what you really need is a tube about the size of a pringles/tennis balls can, maybe smaller.
you fill the end inside the box with polyfil.
then you put your needed item in the tube, but before you pass it thru, you plug the tube behind it with more polyfil, after spraying in lysol.
thus you have a little 'airlock' of sterile space in between 2 wads of polyfil filtering the air.
then you just push thru the outer wad of polyfil until the item drops into the chamber, and your 'airlock' is ready to be re-loaded if needed.
follow my drift ?

Thats a good idea
I figured that the positive pressure was great enough to ensure that no air would enter the glovebox. But w/the pringles can it would be sure that nothing would enter. Im working on some plans now to build a Deluxe Glovebox, that would ensure no contamination and have the room and extras to be comfortable and convenient. I will most likely use your idea and just elaborate on it.
I will be sure and take pics, and type up step by step instructions to share w/the board. Ill keep you posted

sounds good to me, we need all the good glovebox stuff we can get as that's an area many newbies shy away from but good ilustrated threads like this really help build confidence.
appreciate you making the effort to share with us.

yup, I like to share w/discouraged people, cause I used to be there. Had to read alot and experiment, but it all pays off.
