Are there all low-pressure spray guns with HVLP technology?
No, low-pressure spray guns also include APR and LVLP. Low pressure does not refer to the air pressure at the air inlet pressure, but rather the pressure at the tip should be less than 2.5 bar.
Both water-based and oil-based paints can pollute the environment and cause harm when sprayed. This is why the use of HVLP spray guns has been mandated since the 70s in the USA. To this day, these guns are the mainstay of low-pressure spray guns. But while HVLP paint guns are eco-friendly and paint-saving, they also have some drawbacks. Until the APR (acronym for Air Pressure Reduced)type, medium-pressure guns existed and became famous. APR-type spray guns combine the low-pressure and eco-friendly features of HVLP while improving its shortcomings.
The following is a comparison list of our CFC series HVLP and APR.
| ITEM | HVLP | APR |
| Air Inlet Pressure | 0.5-2.3Bar | 0.5-2.3Bar |
| Air Cap Output Pressure | 0.7Bar | 1.5-2.0bar |
| Air Consumption | 410~430L/min | 290L/min |
| Paint Transfer Efficiency | ＞65% Save 10% paint than APR | ＞65% |
| Transfer Speed | Slow | Fast |
| Performance& Particle | Fine, coarse particle, wet in the center zone | Good, fine particle, thin in the center zone |
| Spray Distance | 100-210mm Recommended 150mm | 100-210mm Recommended 170mm |
| Application | Basecoat, waterborne paint | Basecoat, clearcoat |
| Equipment | Enough Air Source& Bigger hose | Regular Air Source & Middle hose |
| Price | A bit higher than APR | A bit lower than HVLP |
