“Overspray” is the portion of sprayed paint that does not deposit on the surface to be coated. By its very nature, overspray does not bring any benefit to the coating process. On the contrary, it is a cost factor: it increases the amount of material that must be disposed of, adds load to the filters, […]
Historically, attempts to control airflow in spray booths have followed two different paths: fans assisted by Pitot tubes and dampers actuated by differential pressure switches. Both approaches have significant limitations that have reduced their effectiveness and widespread use in this field. Let us summarise them briefly. Pitot tube sensor The orifice of the Pitot tube […]
Work and organisational psychology has long shown that individual performance does not depend only on personal skills or motivation. It is also strongly influenced by a set of contextual factors, including the overall climate and the way the working environment functions as a system. A specific branch of work psychology, environmental psychology, focuses on how […]
Booth ventilation: a controllable variable (Part 1) A great deal has been written about the economic and operational benefits that can be achieved by applying process control principles to finishing operations. The advent of reliable PLCs and suitable instrumentation – such as pressure transducers and flow meters – has enabled finishing operators to monitor and […]
The choice of the correct paint booth filters has beneficial effects on product quality, worker safety and operating costs. Outside air filters Outside air filters are the first barrier against possible impurities entering the paint booth and are used to filter the larger particles present in the airflow coming from outside. They are generally pre-filters […]
