For those that want to
eliminate electricity
altogether there is an air
push button available.
The co2 bottle hooks in
one side of the air switch
and the output side goes
to the Airnoids. Push the
button and off you go. An
air throttle switch is in the
works which will be more
suitable for the majority
of nitrous racers.
No voltage at all
It is really a lot of fun when something works better than expected. I
can say with confidence that the Airnoids have met every test I could
think of and they performed above and beyond what was expected.

Naturally I like the lack of wires to have to check on a race to race
basis. If you are considering a new system or updating an old one I
suggest requesting the Combo-Flo Airnoids as your first choice. Where
else would you find more flow, lighter weight, no wires, low to no
maintenance and simplicity in one package?
End Game
After this was written the Mini air noids were released. These make it
even simpler and lighter to make a Fogger changeover from electric
solenoids. The operating principals are the same. The specifications are
listed on the Combo-Flo Airnoid page.

Addendum
Maintenance
I have shown that the Airnoids will require little or no maintenance
unless you run a rock through them. Replacing the plunger is a few
steps more complicated than electric solenoids. These steps must be
followed religiously to avoid damage. These can be done by most
anyone but I don't think I would let the team gorilla do it. I am running
out of room here and the repair is basically another story for another
time but I will be glad to train anyone that purchases one or I can do it
for you.
