Sand Pool Filters

This collection holds 27 sand filters from Pentair (14) and Hayward (13), spanning models built for inground pools (14) and commercial installations (13). You'll find side-mount tanks like Hayward's Pro Series and Pentair's Triton C line, bobbin-wound fiberglass commercial tanks in Hayward's HCF Series, and a large horizontal unit in Pentair's THS Series — tank diameters run from 24 in up to 42 in, with the THS horizontal model measuring 42 in x 96 in.

Start with your pad's plumbing and flow needs: filtration area ranges from 3.14 sq ft on the 24 in Hayward Pro Series units up to 26.7 sq ft on the Pentair THS 42 in x 96 in horizontal filter, and max flow rate is listed at 433 GPM on the Hayward HCF 42 in and 535 GPM on the Pentair THS unit. Match tank diameter and filtration area to your pump's flow rate, check the side and vertical clearance a tank needs during service, and confirm how much sand (and pea gravel, where listed) the tank requires before you budget for install — some Pentair Triton C and Hayward HCF tanks call for hundreds to well over a thousand pounds of media, none of which is included.

Within the lineup, Hayward's Pro Series (S244S, S244SV, S311SXV) are lighter side-mount units built for residential and light-commercial use with 1-Year warranties, while Pentair's Triton C and C-3 tanks add ANSI Standard 50 certification and 2-Year warranties on a fiberglass-reinforced tank. The Hayward HCF Series and Pentair THS Series step up to commercial-duty fiberglass or composite-laminate construction, with the HCF tanks carrying a 5-Year parts warranty plus 1-Year labor, and the THS horizontal unit adding NSF approval alongside its ANSI Standard 50 certification.
