| MCB Member | VForce mask fans... I just finished this today. Like a lot of us I wear eyeglasses, and unfortunately they fog up. I've made some custom mask fans for my JT mask before and it was a success ( Link to thread ) so I figured why not try to put a couple of fans into a new VForce mask as well. This time I went for simple and compact. No speed control, just 2 small fans working with 4 AAA batteries. These are the smallest fans I could find. They're 20mm and as you can see, they fit the VForce mask just right. ![]() You could even mount them inside the mask if you wanted... ![]() However, one of the big problems with mounting a fan right on top of the mask like that is that the turbulence from the air creates a lot more noise. It's also not that efficient, since only a small portion of the actual fan area is being utilized. So, in order to eliminate the noise from air turbulence and to maximize the efficiency of the fans, I needed to raise the fans above the mask surface. I broke out the Dremel, looked around for some scrap plastic and made up a couple of "spacers"... ![]() Then, I stuck them to the fans using double sided tape by 3M. The same kind of double sided tape that's used to stick trim on a car. I highly recommend having a roll around, you'll find a lot of uses for it. ![]() As you can see, there is a good amount of space now under the fans... ![]() Everything's starting to come together... ![]() ![]() I used the same method of securing the fans to the mask that VForce uses to secure the visor to the mask. Quite a clever method I must say... ![]() Now, just secure the battery holder with a couple of zip ties... ![]() (It doesn't really stick out much at all) ![]() Solder in a switch, zip ties, heat shrink yadda yadda... ![]() Oh yeah...I also closed up the hole at the back of the fans with some more scrap plastic to make a duct, so the only air going through the fans were being drawn through the mask. If you don't do this, then a lot of the air that goes through the fan will be drawn from *around* the fan. This time I used a microwave macaroni and cheese tray for the thin scrap plastic lol... ![]() And there ya' have it... ![]() ![]()

| Administrator Join Date: May 2006 Location: Trenchtown | Let us know what sort of run time you get with the four AA's on those fans. Also, there is a really tidy 4AA battery pack with included on/off switch with a plastic body that would also be a neat way to secure power for your rig. The fans I used were bigger than the ones you found, but I was disappointed by how quickly I drained those 4 AA's with them. Good luck, D>

For the record, here is the exact ones I used (low speed): Link to product detail page These have an operating range from 4.5-6volts. 4x disposable batteries will give it 6 volts when they're fresh so it should take a while until they drain to the cut off voltage. I'm using AAA cells right now but if those drain too quickly, I'll move up to AA cells.

| Rec Poster | This works VERY well. I was playing with Jaan at Airsports in Ludlow, MA. I was talking to him about how my mask was always fogging and he let me use this same exact mask. I wear glasses and after putting some Extreme Rage lens cleaner/anti-fog, I didn't have any fogging at all. Now I've gotta do something like this to my Brass Eagle Sentry mask. |
