The little blower has a filter on the end of it. May work it may not. Probably the same on the breath deflector.

Glenn – here’s another product to think on. Maybe call your Optometrist and check if they can order a “prescription stick on lens” that attaches to the inside of your clear helmet visor, similar to this product that sticks on the inside of eye wear glasses.

I know they make them for underwater divers, since wearing prescription glasses with their masks is difficult. Alan

Get a length of clear hose and stuff one end down the arm and out the sleeve cuff and the other in your mouth, you now have a breathing hose out side the helmet--- cost $1.29
Used to do this (before fresh air helmets) in off-road racing with a filter attached to get thru the silt beds

Not sure if that would work with the HANS and the close confinement of the chute pack body I have.
I was thinking of a small 1/2 inch tube running up inside the helmet skirt and releasing just a small amount of air just below my mouth.
Thinking of just using another co2 bottle with air instead of co2, a regulator set at 5 pounds (just a small movement of air clears the fog on the glasses), and a tube that I snake up through fire suit and helmet shirt to blow on the glasses. I would need some kind of quick release so that if I had to get out it would pull free without having to touch it (like the jack for the radio ear plugs).
One more race this season and then I have the whole winter to work on it.
However if it is cool in Bowling Green I will have a problem.

I'll give them a call, the problem I see is the face mask has a flat surface and the helemt is curved.
Anyone have any other ideas?

I'll try breathing through a 1/2 inch three foot long hose and see if it works.
If I used a bottle with compressed air in it and let it release just below my mouth I think that would work.
Need the bottle, a regulator.
A few more dollars but the same general idea.
With your idea I would not have to worry about getting hung up getting out of the dragster.
