The Ectoplasmic Entity Projection Unit is a specialized projector made from two enhanced Traps and other parts that utilizes the Ectoplasmic Frequency Monitor to project an imprisoned ghost from out of the Containment Unit in a containment field.  
Kylie Griffin and Roland Jackson secretly used the Projection Unit to bring out the Grundel and question it for intelligence on the second Grundel. They were forced to shut down the projector when Egon Spengler checked on noise in the basement. Roland ruled use of the projection unit was too risky and stored it in a closet. Kylie later tried to use it once more. Roland arrived and helped her. However, as they questioned the Grundel, it enthralled Casey Jackson and helped him escape from the projection unit.
A valve from the projection unit is attached to the Ghost Trap Slot of the Containment Unit. Second, the unit is also attached to the Ectoplasmic Frequency Monitor in order to lock onto ghosts to project. Third, the unit is operated by a remote control.
