Which bag material?

Stainless steel mesh #1, #2 60–400 mesh Reusable
Oil absorbing #1, #2 5–100 µm For removing oil from water

Nominal means the bag captures most, not all, particles of that size. Start coarse for heavy dirt and step down for finer clarity.

Will the bag fit my housing?

Bag sizes are an industry standard, so a #2 bag from us fits a #2 housing from most makers, if the ring style matches. Check the ring of your current bag or send us a photo. Housings are in bag filter housings.
