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

Selecting a Pressure Filter
Available screen sizes include:
Standard Equipment:
50 mesh suction filter (blue)
Use the pressure 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 pressure 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 a coarser
screen mesh for the optional pressure-filter; refer
to
