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.
