Airless Spray
Process
Paint is drawn into the gun by
vacuum and is pressurised. It is
forced trough a small orifice causing
it to atomise. The paint is delivered
to the job by pressure only, therefore
there is little overspray although you
do get fallout. Due to fixed tips a
percentage of the paint can be
sprayed past the job. The transfer
efficiency of an airless gun is 65-
80%
Advantages
• Fast coating time
• Good transfer efficiency
• Low overspray
Disadvantages
• Fixed tips
• Not adjustable
