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 filter maintenance. To establish a preventative maintenance cycle tailored to your environment, Graco recommends inspecting filters every 4 weeks after installation and replacing when necessary. Document replacement intervals and use this as your preventative maintenance schedule moving forward.
