Manual Powder Coating Gun is loaded with amazing technology, to provide you the best finish.

A wide variety of solutions for the electrostatic manual coating to satisfy even the most challenging application requirements.

Easy and automated color change process

All components in contact with powder are cleaned quickly and automatically while the operator is replacing the powder box.

Power: Maximum coating performance

The newly developed PowerBoost technology of the OptiFlex Pro series offers with the 110 kV the highest powder charging capacity in the powder coating industry while complying with safety regulations.

The operator benefits from an outstanding coating performance.

Quality: Best application results

With OptiFlex Pro you coat extremely efficiently and with consistently high quality. The PCC (Precise Charge Control) mode regulates the spray current even in the lowest ampere ranges (0-10 μA) with the highest accuracy. This prevents overcharging of even the most demanding powders such as metallic powder and ensures the highest quality in thick film and multi-layer applications and recess areas.

Control: Master the application!

The new features of OptiFlex Pro also give you a technological edge. The Electrostatic App (E-App) with the integrated line management functions and service features make the coating process transparent and better controllable.

More Power Performance

Thanks to Gema’s PowerBoost® technology manual gun can now deliver 110 kV high voltage!
This outstanding feature gives you extra power to increase transfer efficiency, charge more powder and finish your coating job quicker. All this without compromising the safety of your operators and of your line, thanks to Gema’s advanced protection technology.

PowerBoost: how does it work?

The high-performance technology is based on the combination of three essential components:
● OptiStar 4.0 advanced software for charging process and compliance with safety regulation
● OptiSelect Pro high performance cascade
● NF40 PowerBoost nozzle special design for more efficient charging

NF40 PowerBoost Nozzle

PowerBoost Nozzle characteristics:
● Cloud soft could
wide brush spray pattern >60°
● Material non stick high quality materials
(PTFE / ETFE / PP)
● Application ideal for large parts and fast
coating

PowerBoost: Maximum Coating Performance

PowerBoost: activating
● Direct switch on manual gun OptiSelect Pro
● On OptiStar 4.0 by selecting spray voltage above 100kV
● E-App by typing spray voltage above 100kV

Digital Valve Technology (DVC)

Thanks to the patented DVC technology, Gema’s OptiStar gun controls offer precise and reproducible powder output regulations and improve the film thickness consistency

DVC technology: how does it work?

  • Digital Valve Control (DVC) is the technology used in the OptiStar gun controls.
  •  The flow of compressed air to the OptiFlow injector is regulated by motor-driven valves.

The first choice for efficient manual coating

The OptiSelect Pro gun is characterised by a very robust and durable design. The ergonomic gun lies balanced in the hand, has a good grip and enables you to coat efficiently and faster.

PowerClean for fastest color changes

PowerClean™ efficiently cleans the entire powder path from the injector to the gun tip. This improves performance when processing difficult powders and facilitates color change.

Unsurpassed Gema reliability

The famous Gema guns’ reliability is based on more than 50 years of experience in powder coating and on the high Swiss quality standards. OptiFlex Pro is using a compact setup to deliver the powder to a standard OptiSelect gun.
