There are two types of filters used in hot melt systems. The first, and most popular are the inline filters that go between the hose and the gun. These filters help reduce the transfer of char from the hose into the gun applicator. However, there is another type of filter that is just as important, and commonly overlooked. Your system’s tank filter.
Unlike an inline gun filter, that will come with either a straight, 45 degree or 90 degree filter body that houses a small inline mesh filter and mounts to your applicator gun, the tank filter is simply a long round cylinder that fits inside your tank itself. The tank filter’s job is to filter the glue out of the tank into the hose, reducing any burnt or charred old adhesive in the tank from clogging up your hoses.
Universal Systems SE recommends that you check and replace your tank filter every 500 hours. In order to check the filter, you can locate it in the lower right-hand side of your system tank. You may not need to replace the entire filter, so first check the screen. Below is an example of what the entire tank filter assembly will look like, compared to only the screen.
