What Are Reduced Pressure (RP) Spray Guns?
Reduced Pressure spray guns represent the next evolution in paint application technology, designed specifically to meet the demands of modern automotive refinishing while complying with increasingly strict environmental regulations.
How RP Technology Works
RP guns operate by:
- Using moderately reduced pressure (typically 30-35 PSI)
- Incorporating advanced air cap designs for better atomization
- Featuring optimized fluid nozzles for precise material control
- Maintaining transfer efficiency rates of 65-75%
Key Advantages Over Conventional Spray Guns
- Superior Finish Quality: Achieves smoother coats with fewer imperfections
- Reduced Overspray: Up to 40% less waste compared to conventional high-pressure guns
- Faster Application: Higher material throughput without sacrificing quality
- Better Control: Improved ergonomics and trigger response

RP vs. HVLP vs. LVLP: Choosing the Right Technology
| Feature | RP Spray Guns | HVLP Spray Guns |
|
| Operating Pressure | 30-35 | 15-20 |
|
| Transfer Efficiency | 65-75% | 65-80% |
|
| Best For | Professional automotive work | Detail work, fine finishes | Small shops, occasional use |
| Air Consumption | Moderate | High | Low |
| Material Throughput | High | Moderate | Low |
Professional Recommendation: RP guns offer the perfect balance between HVLP’s efficiency and conventional guns’ speed, making them ideal for busy auto body shops.
