Applications

Advantages

1

High painting efficiency

1.0kg/cm2 middle atomizing pressure, high granular, low fluid speed, 15m/s, compare with tradition one, less turn over, good wrapped

Automotive, motorcycle, household appliances, construction material, metal or wooden furniture

2

Long life, less parts

Long usage and reliable of best tungsten steel needle and seat, self-tight sealing.

3

Special new technology - circular to gun

Improve EST gun, no paint circle to gun head and no silver powder precipitation and causes gun jammed and bad atomizing, no too much waste cleaning solvent and paint.

4

non-hose explosion design

Gun on/off and circle valve are in the front of gun, with difference design of contrary/sequence, to avoid valve jammed, bad hose explosion, increase reliable.

5

Safety

HV system, with over currency or over voltage, auto cut-off, safety protection system.

6

Easy maintenance

Wire, spray gun protection sleeve, to avoid the pollution on gun and wires, good outer view, easy for plastic paper wrapping.

7

Selection of nozzle

To choice proper nozzle for each different objects, flat nozzle, round nozzle, metal round nozzle.

8

Free change for pattern(Special option)

Base on object's shape, flat nozzle, metal nozzle could be adjusted for best pattern and atomizing fly speed by remote control.
