The Pentek BP-420-200 20" Bag Filter is made of a glazed polypropylene felt that is compatible with many corrosive fluids, including acids, alkalis, oils, organic solvents and microorganisms. This felt, which is created by needle-punching two layers of synthetic fibers together, has a higher solids loading capability than similar mesh fabrics. The outermost surface fibers of this filter media are then glazed to forge a bond that reduces migration possibilities.
The semi-rigid cylindrical design allows the filter to be crushed and incinerated for easier disposal. Also known as Pentek, Ametek and US Filter 155396-03 and BP420.
