For mass production factory of small and medium workpiece which consume a huge liquid material capacity with special feature of material saving in significant amount

The combination of electrostatic technology and air spray method

Electrostatic Automatic Air Spray Gun GA5000EAW reproduce the atomizing system from GM5020EAW which is the manual type for nozzle, air cap and needle that it is used same set with automatic type. The different is GA5000EAW structure will include the control section replace handle and trigger in order to use air pressure to switch on/off gun control so the air hose will be different type from manual type but the basis of using pneumatic system are the same which following as below explanation; 

If we said "the best method of paint spraying is AIR SPRARY method because it cover completely surface with the best performance", this message is not exaggerated at all. As the air spray method, the air pressure is the key power to make paint atomization that this atomizing provide the widest spray pattern so the complex surface such as small auto-part for car, aeroplane, door and etc. The air spray method will be the first priority to consider and solve the normal issue of air spray such as waste a lot of paint from atomizing and overspray. Applying the electrostatic technology to use with air spray is the best decision for solving this issue.

As mentioned, electrostatic support paint to bring the paint atomizing into workpiece automatically, combining with air spray and wrap around feature will make a great performance of coating and save a lot of material consuming.

Structure of GA5000EAWIC (Adjust Spray Pattern (Shaping Air) at Spray Gun)

Every automatic spray gun divide sub spray gun type for spray pattern adjustment, first, the GA5000EAWIC which is setting spray pattern at spray gun. IC is came from internal control. The structure are following as below;

Structure of GA5000EAWEC (Spray Pattern adjustment at control unit)

The other sub type of GA5000EAW is GA5000EAWEC that the spray pattern must be adjusted at external air regulator. EC is mean external control or adjustment will be performed at external spray gun which support an operating progress more easy and suitable for spray booth which has limited area for reaching to spray. For spray pattern adjustment, it is required to install additional air regulator for air pattern.

Paint Resistant and Suitable application

Recommended Paint Resistant

Before explain about the suitable paint resistant, it is require to explain about 3 types of water-based chemical (or water-dilutable lacquers) which are following as below;

  • Non-ignitable lacquers

  • Hard to ignite lacquers

  • Ignitable lacquers

As above 3 groups of water-based chemical, it must be applied with non-ignitable lacquers water-based type only for electrostatic water-based spray gun. (Include apply under Aqua Coat system) and the specific resistance of the water-based paint must be between 0.5 kΩ cm and 1 MΩ cm.

Application for GM5020EAW

  • Every application must be comply with non-ignitable lacquers water-based chemical.

  • Automotive part, small and middle vehicle. Currently, the proportion of water-based paint is increased for production line.

  • Aircraft part that it require for water-based paint application.

  • Wood furniture (mangrove or wood which has moisture inside) with complex surface.

  • Metal work but the material should be stainless or another type of metal which rust resisted.

  • Plastic and glass (Require the state solution coating before using electrostatic gun)

  • All above must be using within spray area which install ground system and has safety compliance.

Some automotive part which require water-based paint

Suitable Viscosity Level of GA5000EAW

The viscosity rate is referred to lacquer as the main material and the recommend rate scale is DIN Cup 4 which is the viscosity cup with diameter size at 4 mm.

The recommend viscosity rate is 15 and 30 DIN sec according to below tale (Remark: DIN4 is the standard viscosity unit of industry at Germany, the measurement unit is second by counting from timing liquid fall down flow from cup. The below table is the compatative table with other standard rate)

The guidance of viscosity table for GA5000EAW

The recommend rate is 15 and 30 DIN Cup 4 sec so if we use the other standard rate, please refer to number on row 5 to row 12 in left table Therefore, the viscosity rate in the same row can use. For example, if you use ANEST IWATA NK-2, the recommend rate is 11 ad 31 NK-2 sec.

Due the automatic spray gun will not include the hose package so it should be purchased separately item. The hose item for water-based is WAGNER GA EAW hose and suitable air hose for this spray gun.


Paint Resistivity Meter


If you don't sure about material that there have suitable resistant rate or not, WAGNER has paint resistant meter which are RS500 that it show the figure rate from Ohm kOhm and mOhm.

Feeding unit for Electrostatic water-based spray Gun GA5000EAW

(Please click "Details" for further information)

Suggestion for choosing feeding unit

The feeding unit section will present both normal version (solvent-based paint version) and stainless version (water-based paint version) within the same content. In order to select correctly feeding unit. Please choose the stainless version as priority to make consideration. In case of pressure tank, please select the stainless pressure tank version because the feeding and tank must be kept in plastic cabinet throughout the operating time.
