A Comparison: Conventional versus HVLP Spray Guns
Because conventional spray guns require a much higher air cap pressure to atomize
the paint than HVLP Spray Guns, conventional guns have lower transfer efficiencies
and more overspray.
This translates to a significant paint/material savings for HVLP guns, in addition to
making them more environmentally friendly.
To qualify as HVLP, the dynamic air pressure going in the Air Cap must be a maximum
of 10 PSI. The lower the air pressure, the less bounce back and overspray.
