These recommendations are service level guidelines

- actual service levels required in your factory
will vary based on environmental and operating
conditions. High or low volume adhesive usage, as
well as adhesives that contain a powered release
agent or are otherwise dusty, will have an impact
on the frequency of 󰘰lter maintenance. To establish
a preventative maintenance cycle tailored to your
environment, Graco recommends inspecting 󰘰lters
every 4 weeks after installation and replacing when
necessary. Document replacement intervals and
use this as your preventative maintenance schedule
moving forward.
