Time to Replace Your DE Grids?
Our DE Grids are used on the most common pool filters including American Products, Pentair, Hayward & Pac-Fab. Most DE Filters will require 7 Full Grids and 1 Partial Grid. Typically DE grids last about 5 years so if it has been longer than 5 years than now is the time to replace your DE grids.
Things to Consider When Replacing Your DE Grids
Note: Collar has open slot (2 notches). Length is measured from one end of the grid to the other (collar not included).

I have a 15 yr old Nautilus INS Pac Fab 48 DE filter. Works great. Also own new set of fins for it. After last cleaning now dripping from lower piping assembly underneath/within the skirt/housing below the tank. I think it is probably just o rings etc on that lower piping assembly. 1. What would I need to purchase? Try this first? OR 2. If I buy a new Pentair FNS Plus D.E. Filter, will I be able to use the whole new set of fins I already have for the Nautilus INS Pac Fab 48 DE filter
Hi Rick, I would first start off by replacing key # 26, 31 and 32 located on the Pac Fab Nautilus INS Parts Break Down Page. If you do end up going with a complete FNS Plus 48 Filter then the individual grids will work from the INS to the FNS Plus but the top and bottom manifold are different. So if you have a pre-assembled grid pack you will need to remove the grids.

When I removed the old grid assembly it was totally caked with old DE dirt. Even after back washing. This is the first time disassembling. Brought home about a year ago. Ordered new grid due to DE dirt being pumped back into pool. Wish you offered a complete kit with all 8 grids. Did not understand what a partial grid was until I disassembled the filter unit. Partial means one of the grids a smaller. So I did not order the partial grid. Will have to order this part and disassembly filter again to install this part. Could not find clear instruction on reassembly of grids. Figured it out after about 1/2 an hour. Need to assemble it upside down. And the grids need to start outside of the bottom filter locator circle. There is this molded in circle in the filter locator. The tips of the filter need to be outside of this circle. For the grid to fit properly.
(5 out of 5 stars) D.E. Filter Grids: OEM, great price, on time
Reviewed By: Ron in Calif. from Sacramento, California ()
Pros: On time, OEM, super price
To be honest I had some trepidation because of some less than stellar reviews. But the price was irresistible. The fileters were shipped same day as promised, arrived within 5 business to Calif. as promised (with the FREE shipping), and were OEM filters in perfect condition. And I saved a boatload of money over other online sellers and my local pool supply. I will definitely use them again.
(5 out of 5 stars) Great Grid

All of our grids were old and tore and it was difficult to keep the pool clean. It was great to receive these grids and we are having an easier time in keeping the pool clean. The on-line ordering was easy and product was received within the time specified.
