500 Series
Single purpose nitrous and fuel Airnoids are
used when a combined unit is not practical
or individual activation is desired. If
independent activation of the nitrous and
fuel Airnoid are needed an actuator will be
required for each.

The nitrous Airnoid has " npt inlet and
1/8" npt bottom outlet while the fuel version
has an 1/8"npt inlet and outlet. The fuel
Airnoid is available in a bottom outlet or
conventional horizontal outlet. The
respective weights are 10 oz for the nitrous

with .125 plunger lift while the fuel checks
in with a .156 orifice and .100 of plunger
