2001 new invention ! |
Trend of gun development! |
Compare with prsent conventional & HVLP gun : Low air consumption, high transfer efficiency, better atomizing |
"LVMP" = Low Volume Medium Pressure
Higher transfer efficiency than HVLP gun
Higher fine atomizing than HVLP gun
Less air
consumption than HVLP & conventional gun
"LVMP" guns were working around Japanese car plant, and quickly spread out in industry !

Theory: The difference of the transfer efficiency between LVMP and HVLP or conventional gun depends on air velocity. With any guns, the air velocities are in the sound-speed area when an instant of coming out from the air cap. However, it generates large difference when it becomes the distance of approximately 200mm. Therefore the transfer efficiency of LVMP gun is better than HVLP even atomized with higher air pressure.
