Pentair 320 SqFt Clean & Clear Plus Air Bleed Tube Assembly

The Pentair 320 SqFt Clean & Clear Plus Air Bleed Tube Assembly (part number 190050 or 190050Z) is a specialized internal aeration and venting component designed exclusively for the vertical core structure of the mid-to-high capacity Pentair Clean & Clear Plus 320-square-foot cartridge pool and spa filtration systems (model CCP320). Fabricated from a combination of a semi-rigid, high-density polymer tube and a porous mesh filter fabric tip, this elongated assembly hooks directly onto the top internal manifold or collector grid and extends downward into the bottom tank core. Its primary operational role is to facilitate continuous, automated internal venting by drawing pocketed air out from the absolute peak of the filter tank dome and safely funneling it down through the return piping matrix before it can compress. By constantly clearing trapped air, this tube maintains a completely flooded hydraulic state inside the vessel, ensures uniform water distribution across the delicate cartridge fabric pleats, and prevents air-bound pressure spikes or dangerous structural vibration surges under continuous operational pressures up to 50 PSI. Engineered to remain permanently submerged in a highly dynamic, chemical-laden environment, it completely resists degradation from concentrated chlorine, bromine, salt-chlorine generator outputs, and seasonal acid washes without swelling, clogging, or turning brittle. Due to its long, narrow, and lightweight plastic-and-mesh composition tailored to fit the interior height of the 320-square-foot tank shell, this individual air bleed tube assembly carries a net product and shipping weight of approximately 0.15 to 0.30 pounds (about 2.4 to 4.8 ounces).
