Electrostatic bell spray gun RA20
No.
BF RA20
Intro.
High-speed centrifugal atomization automatic electrostatic spray gun
RA20 high speed bearing electrostatic cup gun series
RA20 high speed bearing electrostatic cup gun series
Features- Large bell cup、High rotation speed：Large air turbine，high atomization capacity、fast operation speed.
- Tungsten steel paint valve design：on/off once per second, long life, easy to disassemble and maintain from the outside.
- Swirl airflow design: according to the workpiece size, structural shape, and paint characteristics, the strength of the swirling airflow can be remotely adjusted to achieve better large-area spraying, dead-angle spraying, and metallic paint spraying.
- Uniform ultrafine particle size and high transfer efficiency: High-speed centrifugal atomization, uniform spray width and electrostatic repulsion atomization form an ultrafine particle size smooth paint film, and the transfer efficiency can reach 90%.
- Built-in valves, energy saving, and emission reduction: Paint on/off valves, return valves, and waste liquid valves are built-in; the paint is less consumed, solvent is less consumed, and the operation time is shorter.
- Automatic cleaning inside and outside the bell cup: no need to enter the spray booth for manual cleaning.
- Insulation design of the gun body: wide range of paint applications and the effect of electrostatic coating is improved.
- Static insulating ring design: suitable for use metallic paint and high conductivity paint.
- Speed display, constant speed option: built-in optical fiber for speed measurement and electronic digital readout of speed. Automatically maintain constant speed closed loop electronic control.
- Easy maintenance: protective cover for pipelines and spray guns, prevents pollution of spray guns and pipelines, round appearance, easy to wrap with anti-paint plastic paper.
- Safe internal high voltage: built-in high voltage system, no high voltage cables, increasing safety.
