Typical HVLP Design

Turbulence inside gun creates static charge

• Coating particles repel one another forcing some out of the column
• Contaminations with opposite charge are drawn into coating

Higher air pressures required

• 25-40 psi at the gun inlet to produce 10 psi at the air cap
• Loss inside the gun is 15-30 psi

High internal pressures cause "explosion" at air cap

• Air blown out of spray column
• Coatings particles carried away with air, creating booth "fog"

DUX Design

Straight passages and sweeping curves

• Reduce friction and turbulence

Fewer Obstructions

• Fluid needles, springs, and other parts separated from airflow passages

Minimized air travel distance

• Less wall friction = lower pressure

Less air expansion at air cap

• Lower operating pressures result in less explosive effect
