MUNI-3-3FL Municipal Water Filter Housing
The Harmsco MUNI-3-3FL is a stainless steel municipal water filter housing in the Municipal Hurricane Swing Bolt line, engineered for community drinking-water systems that need serious flow capacity. Hurricane cyclonic up-flow separation spins solids away before the cartridge stage, extending cartridge life and cutting operating cost, while the tool-light Swing Bolt closure keeps cartridge changes fast for plant operators.
The MUNI-3-3FL handles flows up to 300 GPM at 150 PSI through 3″ flange connections, holding 3 cartridges in a 9.6 Sq. Ft footprint. It is built from 304L or 316L stainless steel with an electro-polished finish and is available in a high-temperature configuration. The six-size Municipal Swing Bolt line scales from 100 to 1,600 GPM so systems can grow without changing platforms.
The MUNI-3-3FL municipal water filter housing accepts Harmsco’s NSF-certified cartridge range — including LT2-focused media for cyst reduction plus Polyester-Plus, Poly-Pleat, All-Poly, Carbon Block, and High-Temperature options — letting operators match micron rating and media to source water and compliance targets.
The MUNI-3-3FL serves municipal drinking-water treatment, EPA LT2 surface-water compliance strategies, well fields, reservoir and spring sources, and district water systems. Harmsco has manufactured filtration products in the USA, in Riviera Beach, Florida, since 1958.
