How It Works; Power Painters; Container; Suction Set - WAGNER W 140 P Training Manual

•

Power Painters

utilise an airless piston pump in the head of the unit to spray paint. Airless
refers to a method of spraying paint utilising high pressure to atomise paint by
forcing it through a small tip (orifice) opening.
•

Container

holds the material to be sprayed. 600ml and 800ml containers are available
depending on the model.
•

Suction Set

channels the paint to the pump from the integral container. Paint can also be
drawn from a paint can when using the suction extension supplied with each
model.
• Valves
During the backward stroke of the piston a vacuum is created in the
pump by the seal from the swirl valve to the housing. On the forward stroke
the piston forces paint past the sealing block, swirled through the head and
finally atomised within the spray tip to spray paint.
