Fan widths measuring 8" to 12" (20 to 30 cm) are preferred
because they offer more control while spraying and are less
likely to plug.
Piston Lube
Specially formulated to prevent materials
from adhering to the piston rod, which
becomes abrasive to the upper seals.
Piston Lube will break down any material
that may accumulate in the oil cup and
keep it from drying.
Accessories
Airless Tip Selection
Tips are selected by the orifice size and fan width. The proper
selection is determined by the fan width required for a specific
job and by the orifice size that will supply the desired amount
of fluid and accomplish proper atomization.
For light viscosity fluids, smaller orifice tips generally are
desired. For heavier viscosity materials, larger orifice tips are
preferred. Please refer to the chart below.
