ELECTROSTATIC GUN GM5020W

Electrostatic Spray Gun for Water-Based Liquid Only

Huge Effect from Volatile Organic Compounds (VOC)

Currently, the ideal of reducing pollution from VOC in order to protect and secure environment is the priority matter for industry. The reducing of VOC pollution can be done by using water-based liquid to replace solvent-based liquid from some production line. Many of factory has a requirement of water-based application so the painting equipment manufacturer such as WAGNER must complies this regulation and develop equipment for water-based paint.

Even the WAGNER electrostatic liquid spray gun must be complied with this regulation without exception, WAGNER develop new electrostatic liquid water-based spray gun under the name of GM5020W.

To make it be understand clearly the reason why the water-based paint is the significant matter for electrostatic spray gun (and all kind of paint equipment), we will explain about the summary of VOC chemical because this is the main reason to consider the replacement by water-based paint.

VOC: Volatile Organic Compounds

 

When we talk about solvent-based paint, the main component of this chemical is VOC liquid. You may meet a lot of. VOC application in various industry. As the component of VOC is organic carbon which is volatiled in normal ambient temperature and left behind in eco-system. If there is no suitable control procedure for this chemical, it will make damage to environment. That's why the new generation of spray gun or painting equipment is designed to reduce atomizing rate and reduce risk of overspray. Even the electrostatic spray gun also complies this spray method and develop by adding electric charge into water-based paint in order to make wrap around effect. 

Water-Based Paint for Electrostatic Spray Gun GM5020W

As the water-based paint nature has large partical, low resistant and high conductive. Therefore, the solvent-based version (GM5000) can not apply with this paint because the different in internal structure of gun.

Generally, many of water-based material is not 100% pure water but it is mixed with solvent material but we can identify that this chemical reduce the VOC pollution already. However, this material is required for electrostatic water-based spray gun only because they have water-based chemical component.

In other hand, the lay out of equipment is different from solvent-based paint because the feeding section such as paint container, feeding unit or any accessories which related to feeding procedure must be isolated within plastic cabinet which is the electric insulation. There have more details in next topic.

Special Feature of WAGNER Electrostatic Water-Based Spray Gun

New generation of manual electrostatic spray guns born to

significantly ease the work of the painter.

1. Flexible Electrode

The ultra flexible electrode provides a reproducible performance of the gun. This guarantees excellent wrap around and high transfer efficiency.

Remark:

Even the electrode needle is flexible, we suggest that it should not be bended or touch with workpiece every case in order to maintain long useful life.

Flexible Electrode

2. Human Engineered Design

Designed for reducing operators fatigue. The right combination of ultra light weight, ergonomic design, low trigger force and excellent balance lead to a gun with optimum working comfort for small and large hands.

3. Robust Design

Rough environment, intensive usage, different spraying materials and more is what the GM 5000 range is designed for. Replaceable hook for low service costs.

4. High Safety Standard

The GM 5000 gun range is compliant with CE and Atex Zone 1 standard. The grounding of the gun is monitored by the control unit for maximum safety of the painter. If grounding is interrupted high voltage is cut off.

5. Excellent Finishing quality

Innovative nozzles and air caps specifically developed to create a pattern with ideal particle size for perfect combination with electrostatic charges to achieve superior performances and quality.

Integrated control panel

Recipe

The recipe will e changed on spray gun by pushing the button on the spray gun by following 3 recipe in order to support the changing procedure without push button on control unit for obtain the optimal value of each workpiece and suitable for user in each operating round.

However, the details of setting the recipe is required to performed on control unit. Especially, the high voltage rate, current rate which is set based on condition of workpiece for getting the best performance of wrap around. (Please see more details in technical data of VM5020W).

LED signal from spray gun

The green light on led is signal for current recipe used. Each color has a meaning are following as below;

 

  • Green Light is mean the spray gun is normal condition

  • If orange signal have been shown, it mean the grounding is issued. The problem may occur from distance of workpiece ad spray gun, the paint resistant is not suitable for using so it should be check this problem immediately and also check the other related problem based on reference of user mannual

In control panel, the main button which is used for change recipe. The signal will be sequenced by number of recipe by R1 R2 and R3 and green led light is signal for current recipe.

Voltage switch on/off

Switch on/off for high voltage for safety of flushing process or using under special condition.

Plastic Insulator Cabinet (For Electrostatic Water-Based Spray Gun)

Electric Insulator Plastic Cabinet

The plastic cabinet will be the electric insulator by nature. WAGNER design this cabinet to keep all kind of feeding unit and has a special channel to connect hose from feeding which inside cabinet into spray gun from outside cabinet. In addition, this cabinet can comply both low pressure feeding unit and high pressure feeding unit. For further information, please see in technical data of aqua coat.

Isolation of feeding unit for safety purpose

As the water-based paint has high conductive ability, the feeding unit area will convert to be high conductive area. In the past, the feeding unit area must be isolated and place within iron cage for safety purchase and protect people who walk near isolation area but WAGNER has better solution about efficiency of space using so they create the Aqua Coat plastic cabinet that it is the electric insulator by nature and contain all feeding device such as feeding pump and container. Please see the below picture as the example of area for each related equipment of water-based paint.

Paint hose that connect between pump and spray gun. There have channel in cabinet surface for hose linking from inside to outside.
