High Volume Low Pressure-HVLP
High Volume Low Pressure is a term that I learned back in 1970's. This was first used on a large scale in "industrial ventilation" designs. They used this basic principle in an effect to save energy. Local Exhaust Ventilation to save energy when gasoline was $ 0.25 per gallon.
HVLP technology is now used in spray guns used for finishing wood.
