Harmsco INV Hurricane Involute Housings
The INV series is the highest flowing housing produced by Harmsco that accepts 40" L x 2.5" or 2.75" OD cartridges. This line features patent-pending Involute technology, the most recent innovation from Harmsco, which promotes even distribution of contaminants across all filters in the housing. With this even distribution comes increased life expectancy for filters, larger filter capacity, and, overall, reduced operation costs. An INV housing can filter up to a maximum of 1900 GPM, and can be made to accept either DOE or 222/Fin cartridges. With a massive selection of cartridges at their disposal, these units give a number of filtration solutions for industrial and municipal applications that require high flow rates. Harmsco's Involute technology, akin to their Hurricane technology, creates a rotational flow and combines cartridge filtration with cyclone separation. The NSF-61 certified INV series allow one to choose between 304, 316, or Duplex stainless steel, Buna-N, EPDM, or Viton o-rings, and sanitary, BSPT, or victaulic connections for all models.
A chosen housing for utility water, cooling tower filtration, and municipal waste water treatment (among many other applications), this electropolished line also features legs which easily drill into place and two separate drains (one for inlet fluids, one for outlet fluids).
