Hayward Perflex W3EC50C93S D.E. Filter System: 25 Sq Ft Filter and 1.5 HP Pump for Above-Ground Pools
The W3EC50C93S is the top-of-range above-ground PerFlex system, pairing the 25 sq ft Flex-Tube D.E. filter with a factory-matched 1.5 HP PowerFlo Matrix pump. It delivers 2-micron D.E. filtration at up to 50 GPM without a backwash valve, drain line, or grid teardown. The bump handle cleans the Flex-Tubes in under a minute, redistributing the existing 5 lb D.E. charge without wasting treated pool water or adding fresh media.
The 1.5 HP pump gives this system more circulation capacity than the W3EC40C92S (1 HP), making it the right choice for larger above-ground pools or longer plumbing runs that require more pump head. If you already have a pump, the W3EC50AC filter-only is available separately.
Hayward W3EC50C93S Perflex D.E. Filter System Key Features
- Factory-matched 1.5 HP PowerFlo Matrix pump - Higher output than the 1 HP W3EC40C92S, suited to larger above-ground pools and longer plumbing runs where more pump head is needed to maintain flow. Clear strainer cover, oversized basket, thermal overload protection.
- 25 sq ft filter area - More filtration surface than the 20 sq ft models, with a 50 GPM flow ceiling and longer intervals between bump cycles at equivalent pool sizes.
- Patented Flex-Tube design - Bump-to-clean mechanism reuses the 5 lb D.E. charge rather than flushing it. No backwash valve, no drain line, no fresh D.E. after most cleaning cycles.
- 2-micron filtration - Removes particles significantly finer than sand or cartridge filters on the first pass.
- Clamp assembly - Quick tool-free access to the filter interior for D.E. recharge and Flex-Tube inspection.
- Self-venting design and integral check valve - Air is automatically expelled; backflow is prevented whenever the pump is off.
- Heavy-duty glass-filled PPL tank - Corrosion-free outdoor construction.

Hayward W3EC50C93S Perflex D.E. Filter System Frequently Asked Questions
What is the difference between the W3EC50C93S and W3EC40C92S?
The W3EC50C93S has a larger 25 sq ft filter (vs. 20 sq ft), a 5 lb D.E. charge (vs. 4 lbs), a 50 GPM flow ceiling (vs. 40 GPM), and a 1.5 HP PowerFlo Matrix pump (vs. 1 HP). Choose the W3EC50C93S for larger above-ground pools, higher pump outputs, or longer plumbing runs that need more head to maintain adequate flow.
Does D.E. powder come included?
No. 5 lbs of pool-grade D.E. must be purchased separately. Add it through the skimmer with the pump running on initial startup. Do not use food-grade or pest-control D.E.
Is this system suitable for in-ground pools?
No. The PowerFlo Matrix pump is an above-ground pump designed for the resistance characteristics of hose-based plumbing. For in-ground applications, see the W3EC65A or W3EC75A.
How often does the D.E. charge need replacing?
Much less often than a conventional D.E. filter. The bump mechanism redistributes and reuses the existing charge rather than flushing it, so most owners recharge fully only one to three times per season.
