GA5000EACW
For large workpiece from machine make or large complex workpiece and require high pressure spray for fast operating
High Pressure Spraying with supporting from electrostatic technology
Electrostatic Automatic Air Spray Gun GA5000EACW reproduce the atomizing system from GM5020EACW which is the manual type for nozzle, air cap and needle that it is used same set with automatic type. The different is GA5000EACW 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;
The example of large workpiece, machine making by order, water tank, large metal furniture that it take operating time more than other type of workpiece even there have an electrostatic technology to support. In order to achieve the objective of production that there have the time limit but it need to increase a production volume and reduce the material consumption. We can separate the condition and solution for following below requirement.
1. Quick Painting Cover a huge surface area and spend a few timing. Spraying with airless high pressure can respond this requirement.
2. Cover totally a workpiece surface for whole body Spraying with air spray can reach the paint into the workpiece surface.
From above 2 requirements, there have only 1 spraying method that can achieve a both 2 requirements in the same spray gun which is AirCoat method (Air assist airless). This method combine the advantages of air spray and airless spray which are the performance of spray pattern control (air spray) and high speed spraying without air (airless) then it make 2 main component of aircoat spray that it include high pressure spray pattern with start from 100 - 150 bar and low air pressure to control the high pressure spray pattern that it support to make atomizing flow cover the workpiece surface better than using airless spray only. The result that it spend a few operating time as it is sprayed with high speed pattern but it still cover completely a workpiece surface. So the GA5000EAC can achieve the 3rd requirement on below;
3. Reducing the material consumption rate The electrostatic technology support the wrap around effect that it help to save the material consumption rate and also increase pace of operating time.
Therefore. the combination of 3 advantages make the GA5000EACW to be high speed spray gun, high performance of wrap around effect and material saving so many of user use this spray gun for large work piece.
Component of GA5000EACWIC (Pattern Adjustment at Spray Gun)
Every automatic spray gun divide sub spray gun type for spray pattern adjustment, first, the GA5000EACWIC which is setting spray pattern at spray gun. IC is came from internal control. The structure are following as below;

2. Paint Connection NPSM 1/4''
3. Control air connection D6
4. Gun cable connection
5. Shaping air or atomizing air connection D10

Spray Pattern Adjustment for EACIC
Position A is screw regulator for air pattern adjustment
Structure of GA5000EAEC (Spray Pattern adjustment at control unit)
The other sub type of GA5000EACW is GA5000EACWEC 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. It is required to install the additional air regulator for spray pattern.

3. Control air connection D6
4. Gun cable connection
5. Spray Pattern Air (Shaping Air) connection D8
Remark:
The significant different between EACWIC and EACWEC is connection position no.1 due EACEC require that air hose D10 to connect this position for atomizing air. In other hand, the air hose for spray pattern must be linked between spray gun and external air regulator.
For other connecting position in each air hose diameter of EACEC will be located in different position of EACIC.

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 GA5000EACW
-
Every application must be comply with non-ignitable lacquers water-based chemical.
-
Automotive part, middle and large 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 simply surface.
-
Metal work but the material should be stainless or another type of metal which rust resisted.
-
All above must be using within spray area which install ground system and has safety compliance.

Suitable viscosity rate for GA5000EACW
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 25 and 40 DIN sec or even the viscosity at 60 DIN sec, it is still usable as 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 falldown flow from cup. The below table is the comparative table with other standard rate)

The guidance of viscosity table for GA5000EACW
The recommend rate is 25 and 34 DIN Cup 4 sec so if we use the other standard rate, please refer to number on row 10 to row 15 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 25 and 49 NK-2 sec.
