How this calculator works: Lab testing and customer testimonials have demonstrated that DUX spray guns reliably achieve a Transfer Efficiency (TE) that is 15-40 percentage points higher than other spray equipment. The exact percentage increase is determined by many factors, including the type of equipment being replaced, coating material, and operator skill. This calculator uses a fixed 25% increase in TE (approximately the middle of the range) with a maximum DUX TE of 90% - although higher TEs may be possible depending upon conditions. Please note that your actual results may vary depending upon the factors above. To request a demonstration and a customized savings calculation based on actual demo results, please contact DUX Customer Service at 1-888-389-2732.
