Product details

The Unicel FG-3015 is a rectangular DE filter grid measuring 15-3/16 inch by 18 inch, with the exit port at the top center. It is catalogued with the Sta-Rite System 3 DE filters, models S7D75 and S8D110.

How it is built

Unicel rectangular grids use a reinforced center core, which is what stops the grid from folding under the pressure of a loaded filter. The core is covered in polypropylene cloth that resists mildew and rot, and the seams are stitched with chemical resistant heavy duty string and then sonic welded so they will not fray in service.

When to replace

A grid that is torn, worn thin, split at a seam or bent at the core will pass DE straight into the pool. The giveaway is a dusting of powder on the floor after every recharge. Measure the old grid and check the port position before you order, since a DE filter takes a set of grids in more than one size.
