Pentair 10 5/15" Triton C and C-3 Air Vent Strainer Spacer for Triton C Sand Filter

The Pentair 10 5/16" Triton C and C-3 Air Vent Strainer Spacer (part number 154562) is a specialized internal fluid-management plumbing component designed exclusively for the air bleed and ventilation arrays of commercial-grade Pentair Triton C and Triton C-3 side-mount high-rate sand filtration systems. Injection-molded from a heavy-walled, high-impact PVC and engineering polymer composite, this rigid, elongated 10 5/16-inch structural spacer acts as an elevated conduit sleeve within the peak of the fiberglass tank core. Its primary operational role is to bridge the gap between the upper bulkhead and the air vent strainer assembly, maintaining the precise vertical positioning of the internal automatic air relief network at the absolute highest point of the pressure vessel.

By keeping the air bleed ports securely anchored above the shifting silica sand media bed, it allows trapped air pockets to be cleanly vented out of the tank dome through the external manual air relief valve. This critical positioning prevents the internal air lines from clogging with sand particles, eliminates systemic pressure-lock, and ensures the commercial vessel can safely manage high fluid velocities and sustain continuous internal hydraulic operating parameters up to 50 PSI without weeping or experiencing fluid bypass under heavy pump vibration surges. Engineered to remain permanently submerged in a highly dynamic, chemical-laden environment, its robust plastic framework completely resists structural warping, cracking, and corrosive degradation from concentrated pool sanitizers like chlorine, bromine, and routine acid washes. Due to its slender, thick-walled cylindrical geometry tailored for large-tank sand filter configurations, this individual internal strainer spacer carries a net product and shipping weight of approximately 0.30 to 0.45 pounds (about 4.8 to 7.2 ounces).
