Product overview
The Pro Grid Vertical DE Filter Part, DE4820 48 Sq Ft is an aftermarket filter grid / DE element built to replace the original component in Hayward filtration systems. In service it provides the surface that holds the diatomaceous earth cake doing the actual filtering. It is a wear item: the fabric tears and the manifold sockets split, which sends DE powder back into the pool. Ours is built with polypropylene fabric on a rigid frame.
