Description: AirCoat combines the advantages of airless and air atomizing spray technology. In addition to an excellent coating quality and significantly lower spray pressure than with airless, the AirCoat process also enables a higher working speed and less overspray than with airspray applications.
The GA 4000AC is part of a modular system. The wide range of nozzles, air caps, base
plates, connection options and mounting elements allows integration into any application
environment. The range distinguishes between an internally and externally controlled
variant:
- Internal control (IC): Air management of the forming and atomizing air in the gun. To ensure a perfect spray jet right from the start, the air is activated before the material valve is opened.
- External control (EC): Enables independent adjustment of the forming and atomizing air through external regulation and control valves.
Features:
- Fast and Constant Open-Close Speed
Fast trigger speed reduces overspray due to closer and more precise trigger positions to the workpiece.
- Smallest and Lightest Gun
The GA 4000AC is the smallest and lightest automatic AirCoat gun on the market. This provides mounting flexibility and fast movement.
- Wide Range of Paints
All wetted parts are in stainless steel. So the gun is suitable for virtually any kind of paint.
- Best Atomization
The new AirCoat atomization provides a softer and smoother spray pattern. Due to the new air cap design, the material pressure is reduced and the spray pattern becomes more homogenous.
- High Transfer Efficiency
The fine and soft atomization combined with a homogenous particle size guarantees a high transfer efficiency.
- Long Lifetime
The new long life packing increases the process reliability and reduces downtime. With the innovative cartridge system, the changing of the packing is simplified and takes only minutes!
- Fixed Settings
The base plate system maintains the position and all settings for reproducable spraying results.
