OptiGun with PowerBoost®
110 kV charging. Maximum penetration.
GEMA's OptiGun GA02/GA03 series delivers the highest electrostatic charging available on any production automatic gun — engineered for consistent finish quality on complex geometries and demanding Faraday cage areas.
Why this product
Conventional guns fail on complex parts.
Recesses, channels, internal corners — wherever geometry creates a Faraday cage effect, conventional automatic guns produce thin or absent powder film. Rework rates climb. Rejects mount. The OptiGun with PowerBoost® and PCC Technology was engineered specifically to overcome these limitations.
- 110 kV PowerBoost® — the highest electrostatic charging available on any production gun
- PCC Technology: Penetration & Corona Control for consistent film build in Faraday cage areas
- SuperCorona electrode delivers extended field reach on complex 3D geometries
- DVC: Digital Volume Control ensures every gun on the line outputs precisely the same powder volume
- MagicCylinder® option for rapid colour change on automatic production lines
- GemaConnect integration for remote monitoring, diagnostics, and production data
Models & Configurations
GA02 or GA03 — choose your specification
The production standard for automatic powder coating.
The GA02 is the baseline OptiGun model — delivering consistent 110 kV PowerBoost® charging with DVC powder output control. Designed for high-volume production lines where throughput and coating consistency are the primary requirements. Compatible with all GEMA reciprocator and axis systems.

How it works
Charge, penetrate, adhere
Powder delivery
Powder is transported from the OptiCenter or hopper to the gun via a controlled Venturi system. DVC (Digital Volume Control) regulates the precise volume reaching each gun independently — ensuring every gun on a multi-gun line applies the same film build.
