OptiFlex Pro Series — Gravity / Box / Hopper Fed
Manual powder
coating gun.
Swiss standard.
GEMA's OptiFlex Pro is the world reference for manual electrostatic powder coating guns — covering quick colour change, high-output production, and standard all-round use. Supplied and supported in India by OptiFinish.
Why it matters
Manual application
should never be the weak link.
In a well-run powder coating line, the gun is where quality is made or lost. Inconsistent kV, poor colour-change discipline, and slow cleaning routines cost finish quality and production time every shift. The OptiFlex Pro eliminates all three.
Fastest colour change in class
Pro Q changes colour in 35 seconds with MagicPlug® tool-free disassembly — keeping multi-colour batch lines moving.
Programmable kV and µA control
MagicControl 4.0 lets the operator set and recall the exact electrostatic parameters for each powder type — no guesswork, consistent results across shifts.
Handles every powder type
Standard epoxy, metallic, thermoplastic, and hot melt formulations — the OptiFlex range covers all powder classes used in Indian production.
Three models — one system

Colour change in 35 seconds.
The Pro Q is built for operations running multiple powder colours daily. MagicPlug® tool-free disassembly lets the operator strip the gun for cleaning in seconds — the fastest colour changeover in its class. Box-fed or hopper-fed configurations available.
The process
How electrostatic powder
application works

01 — Powder fed via Venturi
Powder coating material is drawn from the hopper or box feed through a Venturi system — pressurised air creates suction that pulls the powder into the gun barrel at a consistent, controlled rate.

The OptiFlex Pro is the primary application tool in the powder spray booth — positioned between the dry-off oven and the curing oven. In manual lines, the operator controls gun angle, distance, and traverse speed. In batch automatic setups, the manual gun can be paired with a ZA01 or GEMA ZA reciprocator for consistent vertical traversal.
