PBG Customs Whisper Drive Bolt Valve Chamber for Planet Eclipse EMEK 100 / EMF100 / ETHA2 – Purple

The PBG Customs Whisper Drive Bolt Valve Chamber is a performance upgrade for compatible Planet Eclipse EMEK 100, EMF100, and ETHA2 paintball markers.

The Whisper Drive replaces the factory chamber and increases airflow through the bolt system, allowing the marker to operate at a lower pressure. The design is intended to improve air efficiency, reduce sound signature, provide more consistent operation, and be gentler on paint.

Key Features

Installation Notes

• Lubricate the O-rings before installation.
• Hand-tighten only. Excessive torque can deform the thin three-prong section of the chamber.
• Re-chrono the marker after installation because the increased airflow can change velocity.
