Product Details
IMPCO Model E & PE , Engine Heated Two-Stage Regulator, Two
Negative/ One Positive Outlet Pressure Option
Model E & PE
DESCRIPTION
The model E & PE are engine heated two-stage regulator/vaporizers.
The model E provides a choice of two negative outlet pressures. A
“B” blue secondary spring provides a -1.5” w.c. (-0.37 kPa) output
and an optional “O” orange secondary spring provides -0.5” w.c.
(-0.12 kPa) output. A manual primer is standard on the Model E.
The model PE provides a positive outlet pressure for applications
that require a positive feed system and/or the ability to vaporize
liquid fuel. A heated regulator/vaporizer is not required of CNG
(it is recommended that the Model PEV be used for these systems).
Additional mixture stability is possible with the PE as a result of
a more consistent fuel temperature gained through the use of the
heated labyrinth. The PE is supplied as a fixed outlet pressure
regulator but can be converted to an adjustable unit with the
AC1-74 retrofit kit.
