How to reduce or shut off Compressed Air for Painting Robots

Hi guys,

I am currently working on the optimization of a painting process, and I would like to reduce / stop the compressed air in the painting robots when they are not used.

But it seems that a continuous flow of air is needed to prevent problems with the robot and the painting devices.

Have you experience in reducing the flow of air ? cutting it ? using a smaller compressor so that you can shut down the main one ?

Any idea welcome.

Thanks in advance

A few thoughts, at least as a hobbyist spray painter (no experience with robots).

I would assume the issue with needing to keep air flow through the air brush is to prevent paint from drying out and clogging the nozzle / venturi. Now, for a manual airbrush, one always cleans out the airbrush by blowing water (if water based paint) or cleaning solvent (if oil based paint) when you stop painting. Would there be a way to program a cleaning cycle at the end of a paint run? Of course, the waste generated by cleaning solvents that would need to be collected from the cleaning process could exceed the cost savings from cutting back on the use of air.

You need to get with your compressor company. Using compressed air is really not efficient, but there are some things that can be done to improve efficiency and increase available air. Also remember that compressed air is a system and take a systems approach.
