Black Foam in SpectraMax 190

Hello, I am replacing the fan filter in my SpectraMax 190 and to do this I've realized I might need to remove some black foam inside the spectrophotometer. Does anyone know what this black foam is, what it does, and where I can buy replacements for it? This is a duplicate of this question https://www.labwrench.com/thread/267114/black-foam-in-spectramax-190 because I didn't realize how to post in a specific forum instead of "all categories"
