Advisor to solve problems with compressed air

Compressed air - the driving force for paint atomization
 
... but also the cause of bad paint jobs.
 
100% technically clean air is the basis to ensure flawless tool function.
 
To ensure perfect finishes, compressed air for spray guns must meet the following criteria
  • Sufficient, even pressure
  • Adequate air volume
  • The highest amount of purity
must be available at the air connection of the delivery hose to the compressed air tool. In case one of the above criteria is not fulfilled finish problems may occur that a dissatisfied customer will not be willing to pay for.
 
Compressed air is also required for material delivery in pressure tanks or pumps, gun washers and other air tools. In this case, the same criteria apply the same as with paint atomization.
 
Problems affect the paint job with dust, water and silicone (fish eyes) and shorten the function and lifetime of pumps and pneumatic tools. Have your compressed air quality checked. Find more detailed information in the Product Service section. With the 0/400 modular filter series, we offer a solution according to your requirements and support you by providing the best solution.
 
Air leaks are very expensive
 
Even small, permanent leaks cause considerable cost because compressed air is continuously leaking while the unit is under pressure. With a 1 mm hole diameter at 190 psi, that leads to an annual cost of about $1000.00 when operating the system for 24 hours.
 
Slightly increased air consumption of about 3.5 cfm from an HVLP spray gun for example only leads to an extra cost of about .02 - .05 cents for a partial coating.
 
The enclosed Troubleshooting Chart is a simple aid to detect problems and their causes and provide corresponding remedies to provide finishes the customer will be happy to pay for.

    

100 % technically clean air is the basis guaranteeing flawlessly functioning tools
 
Coarse surface finishes
 
Orange peel, color matching problems and mottling.

    
 
Condensation / oil separation
 
… despite the use of modern compressors, cratering is caused by water or oil at the nozzle.

    
 
Insufficient air volume
 
… in spite of sufficient specifications and system performance filters become quickly saturated. High level of condensation and dust particles in compressed air.

    
 
Particles in paint finish
 

    
 
Pressure drop
 
… in the air supply despite correct installation of compressed air lines, compressor and refrigeration unit.

    
 
Silicone and oil
 
or condensation on the coating causing adhesion problems etc.

    
 
Coarse surface structure during coating
 
... changes in color shades and / or mottling.
