In the dry paint booth the excess paint is trapped by Paint Arresting media and in the water wash paint booth water is used as a media for trapping the excess paint. The paint arresting media used in the dry paint booths are imported and have a higher paint holding capacity . These filters have no risk of electric fire according to European Directive ATEX-91/9/CE. Most importantly it is Non-Carcinogenic. Hence safety and environment is duly taken care of. The clogged filters are easy to replace and easy to dispose off. Prism also offers water wash paint booths with on line paint coagulation system.

This leads to the venturi never being clogged resulting in consistent exhaust air parameters, less maintenance and avoid booth cleaning to remove the sludge formed. The frequency of water change can even be once in a year. On account of this there is a uniform suction available throughout the paint booth resulting in good finish and offer operator comfort. Pressurized paint booths are also available with temperature and humidity controls. The paint booth venturi section and dewatering section is fully assembled, welded and shipped from PRISM factory to ensure consistent performance. The oven is equipped with modern technology energy efficient heaters to dry off the finish paint.
