DIGITAL PRESSURE
GAUGES FOR PAINT SPRAY GUNS
The optimal paint volume with the right pressure
A paint spray gun is a tool for applying paint and dispersion
colours. It enables even results and makes it easier to work
across larger areas and objects.
The paint is atomised to small droplets with the help of compressed
air from a compressor or a pump and applied onto the object.
The drops are deposited onto the object and form a joined surface
film, provided that enough is applied.
The atomisation of drops is created from the pressure difference
generated by the compressor. A negative pressure is produced
through the outflowing air which draws the paint out of the connected
paint container.
The pressures used can be set exactly to the operator's requirements
with the help of KELLER 4L sensor. KELLER manufactures a miniature
digital gauge which displays the precise operating pressure of
the spray gun on a digital LCD screen. These digital gauges are
custom designed to be easily integrated by the Original Equipment
Manufacturer; ultimately enabling the end user to accurately
control the paint spraying pressure.
KELLER collaborates with several paint spray guns industry leaders.
Their products are mainly used to paint vehicles, in the painting
trade or other industrial sectors.
