Filbur APCFGR52 FC-9890 DE Filter Grid, 18 x 17-3/4 inch, Sta-Rite Swimquip DES60 Offset Port
18 in x 17-3/4 in rectangular DE grid with offset exit port for the Sta-Rite Swimquip DES60 filter.
The Filbur APCFGR52 (FC-9890) is the 18 in x 17-3/4 in rectangular replacement DE filter grid for the Sta-Rite Swimquip DES60 diatomaceous earth filter. It seats on your existing manifold through the offset exit port and rebuilds the filtration surface with mildew-resistant polypropylene cloth, so your pump runs at design flow and your water comes back clear. This is the direct one-to-one replacement for Unicel FG-3917 and Sta-Rite OEM part 239000142.

Will the FC-9890 replace my Unicel FG-3917 or Sta-Rite 239000142 grid?
Yes. The Filbur FC-9890 (APCFGR52) is a direct one-to-one replacement for Unicel FG-3917 and Sta-Rite OEM part 239000142. Same 18 x 17-3/4 in rectangular footprint and the same offset exit port, so it seats on your existing Swimquip manifold without modification.
Which filter does this 18 x 17-3/4 inch grid fit?
It is the offset exit port element for the Sta-Rite Swimquip DES60 vertical DE filter. A DES60 grid set mixes several element sizes, so this one fills the 18 x 17-3/4 in offset position. Pull the matching grid and measure it against these dimensions before you order, and if more than one grid is torn or flattened, replace the full set so new and old cloth load DE evenly.
Can I replace one of these myself?
Yes. Shut the pump off, bleed pressure at the air relief, open the filter, lift the grid assembly, and seat this replacement on the same manifold posts through the offset exit port. Reassemble and recharge with fresh diatomaceous earth to your filter's square-footage rating. No tools beyond what the filter teardown already requires.

Let customers speak for us
Loved how fast it got here. It has small wiring and I was glad it was in a protective envelope and it arrived without breaking.
just as listed. well packeged, fast ahip, works fine. purchased to remedy issue with heater and ozone injectorboth operating together. might have been able to just bend old switch a bit but did not try that.
Great customer service and knowledge of product. Asked of compatibility and they had the answer. My intouch2 was not working so I researched new intouch3 from Spa Dealer and they wanted $75 just to come out, then $125 for up to an hr...just to confirm what I already knew. Contacted PST and they had the product and confirmed compatibility. Saved me some $$.Thanks PST.
