Spray Filter
Recommendations
Selecting a Suction Filter
Standard Equipment: 50 mesh suction filter (blue)
Use the suction filter table to identify the screen
mesh for the spray nozzles you are using based
on chemicals products or solutions with a viscosity
equivalent to water.

*The mesh size of the suction filters in this table
are based on spray chemicals or solutions with the
viscosity equivalent to water.
Important:
When you spray with higher viscosity
(thicker) chemical products or solutions with
wettable powders, you may need to use an coarser
screen mesh for the optional suction filter; refer
to
Figure
53.

When you spray at a higher application rate, consider
using an courser optional suction-filter mesh; refer
