manifold and the odorant discharge
manifold. IP54 rated.
E. NJEX LVO Gas Filter. Installed between the
actuation gas regulator and the actuation
gas manifold, this filter provides a 25 micron
coalescent filtration to insure a clean
pneumatic supply.
F. Flow Switch (610F models only). Installed in
the discharge line of the pump to confirm
odorant flow.
