Electrostatic Technology for Air Spray Gun


Air Spray method is paint spray by air-compressed driving and utilize the atomization to get the most efficient. Small workpiece or large object but there is a nook around piece are required to use with air-spray gun in order to attract high volume material paint to surface object and get the best quality of spraying. However, this method consume a huge material paint quantity if it’s used in mass-production.


WAGNER develop electrostatic gun for Air-Spray method to solve the problem of large material consumption rate. GM5000EA support to decease material paint cost for spray in mass-production. Electrostatic bring material paint to wrap around workpiece automatically. Paint will be atomized in proper direction. More time-saving and provide better quality of work. You may see the details of air spray method on below link;

Material Container

Air Compressor

1. Air compressor feed air pressure to spray gun and feeding pneumatic type unit

2. Feeding unit drain material paint (except pressure tank that feeding and paint container are the same unit)

3. Power supply feed electric power to control device

4. Feeding unit feed paint to spray gun

5. Operating control device input control command to spray gun

6. Spray paint to workpiece

Painting booth must be installed with ground system.

Technical Data

GM 5000EA


This is a most popular electrostatic gun. It’s designed for use with solvent-based material and compatible with paint resistant more than 150 kOhm. It’s friendly designed for user, light weight and compact.

GM 5000EAW


W code behind “EA” mean this electrostatic gun are designed for water-based material. Compatible with paint resistant between 1kΩ.cm to 1MΩ.cm. No HV cascade in the gun and special isolated paint hose. It is recommend to use with WAGNER Aqua Code system.


For spray with water-based paint, it is necessary to use with specific equipment as details on below link;

*Temperature is measured by celsius

Application and Accessories


Setting at the fingers tip

Small button panel are located at rear yellow panel that user can change spray recipe on this panel. No need to change at controller. Warning Light also locate at this yellow panel. Green light show the normal situation. Orange light warn immediately user about gun problem.. For example, ground problem occur etc. It also have on/off switch for voltage on panel.

Spiral Hose for Metallic Paints


Special Accessories for Metallic Paints. Not include in gun set.

Flat Air Cap (Left) Round Air Cap (Right)

Unique air cap/nozzle design


4 Aircaps type are following as below;

  • Flat Spray AF5000 small - smaller spray pattern and slow air speed

  • Flat Spray AF5000 wide - wider spray pattern and slow air speed

  • Round Spray AR 5000 D8 - Full cone with swirl and small spray pattern diameter

  • Round Spray AR 5000 D12 - Full cone with swirl and wide spray pattern diameter

Different nozzle diameters from 0.06 and 2 mm are available for flat spray to adapt the spray gun to low and high material flow and viscosities.

Flat Nozzle


8 Nozzle size for each flat nozzle are separated by color in order to select for suitable work.

Flat Nozzle

Round Nozzle has 2 size for diameter. D8 is 0.06 mm diameter and D12 is 2 mm diameter.

Example of Workpiece


From left picture, most of workpiece is small size, corner nook around piece and groove panel. For example, eye-glasses, bicycle body frame, spring and wheel. These workpiece are required to use Air Spray system to atomize paint flow to attach workpiece. When combine with electrostatic technology, wraparound effect will bring all paint to attach quickly surface and support for cost and time saving.
