EcoGun AS MAN EC – Manual Electrostatic Spray Gun with External Charging

The EcoGun AS MAN EC by Dürr is a professional electrostatic manual spray gun developed for precision coating processes using non-flammable paints. The gun uses a dedicated high-voltage controller (EcoHT 80) to externally charge the paint particles, significantly improving wrap-around and transfer efficiency compared to standard air-spray technologies. Because of its robust construction, ergonomic design, and CSA Class I Div 1 certification, the EcoGun AS MAN EC is ideal for industrial production environments with strict safety and quality demands.

Design & Operating Principle

The gun is intended exclusively for hand-guided electrostatic coating within a properly ventilated spray booth.
Electrostatic charging takes place externally through a cable connection from the EcoHT 80 controller. Compressed air supports atomization, while the gun’s air cap, nozzle, and flow-control system ensure precise spray characteristics.

Key factors affecting the spray pattern include:

• Air cap alignment

• Material quantity

• Spray width adjustment

These are all fine-tuned directly on the gun for optimal results.
