ELECTROSTATIC SPRAY GUN
GM5000EAC (AIR COAT)
The combination of Aircoat and Electrostatic Technology
In case of large size object such as gas container, large scale furniture, air plane chassis and etc. These are required spray gun which can delivery material paint with high pressure (not more than 250 bar) but it must provide the good quality spray pattern similar to air-spray gun and reduce material cost and working time. GM5000EAC can comply all those requirements with air-coat method which is a combination between air-spray and airless. It use low-pressure atomizing air to assist airless pattern to be good shape and effect to quality of spray work. When electrostatic gun technology support air-coat method, paint will be attached automatically to object surface with wraparound effect. Support to reduce material cost and working time. It is appropriated to use in mass-production plant. You may see the details of AirCoat spray method in below link;
Overview of GM5000EAC operating structure
High pressure feeding unit
Electric Control Device
Electrostatic Spray Gun
Workpiece with ground cable
1. Air compressor feed air to electrostatic spray gun and feeding unit.
2. Feeding unit obtain paint from material container.
3. Power supply feed electric power to control device.
4. Feeding unit feed paint to electrostatic spray gun.
5. Control device input control command to electrostatic spray gun.
6. Spray to workpiece.
The painting booth must be installed with ground system.
*Temperature is determined by celsius
GM5000EAC for solvent-based material
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.
GM5000EAW for water-based material
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.
In case spray water-based paint, please see the detail of specific equipment for this material type.
Application and acessories
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.
Air Cap with Guard
Flat jet Air Cap
Round jet Air Cap
Unique air cap
Air Caps for EAC are classified into 3 types by color
Flat Spray LV best for low to medium viscosity material. Label is red marking.
Flat Spray HV best for medium to high viscosity material. Label is blue marking.
Round Spray for wide spray pattern
The air caps are color coded to avoid mistakes when replacing them.
Flat Nozzle ACF5000
For narrow vertical or horizontal spray pattern, the size are identified as below table;
Flat jet Nozzle for EAC
Round Jet for EAC
Round Jet R Series
For wide spray pattern diameter, start from smallest R11 (0.11 mm) to R22 (0.22 mm)
