Pentair 240 SqFt Clean & Clear Plus Air Bleed Tube Assembly

The Pentair 240 SqFt Clean & Clear Plus Air Bleed Tube Assembly (part number 190057) is a critical internal air-management component engineered specifically for the Pentair Clean & Clear Plus 240 square foot cartridge pool and spa filtration system. Injection-molded from a high-impact, chemical-resistant polymer composite, this assembly features a specialized, semi-rigid vertical plastic tube fitted with a fine mesh screen or fabric sleeve at its uppermost tip. Its primary operational role is to vent trapped air pockets that naturally collect at the highest point of the pressurized tank dome during everyday filtration cycles, automatically channeling the compressed gas down through the center manifold and safely out into the pool return lines. This continuous venting action ensures the filter vessel remains completely flooded with water, preventing dangerous pneumatic pressure spikes up to 50 PSI and eliminating air pockets that can cause structural shuddering or reduce the effective filtration surface area of the internal cartridges. Built to endure constant submersion in highly chlorinated pool water, bromine, and seasonal chemical acid washes without warping, cracking, or suffering mesh degradation, this durable assembly ensures long-term operational safety. Because it consists of an elongated but highly streamlined and hollow plastic tube architecture, this individual air bleed assembly carries a lightweight product and shipping weight of approximately 0.15 to 0.20 pounds (about 2.4 to 3.2 ounces).
