UNSPSC 31421511: Aluminum high temperature sintered filter

Aluminum filter sintered at temperatures above 1150 degrees F or 620 degrees centigrade

UNSPSC 31421511 Aluminum high temperature sintered filter is a Commodity code that does not see relevant recent activity in state and local procurement. The recent opportunities tagged under this code span refrigeration equipment replacement, trail and bridge construction, vehicle lifts and concrete restoration, erosion control, utility relocation, generator installation, boardwalk construction, and equipment purchases for industrial and educational use—none of which involve aluminum sintered filtration media or components. The code's nominal scope—high-temperature sintered aluminum filters typically used in air separation, gas purification, or specialized fluid filtration—does not align with the construction, infrastructure, and equipment procurement actually appearing in the tagged opportunities.

State and local buying under this code, when it does occur, would typically involve county departments, municipal utilities, regional authorities, and special-purpose districts procuring replacement or maintenance parts for industrial filtration systems, water treatment plants, or HVAC/compressed-air infrastructure. No recent solicitations in the source document directly name aluminum sintered filters or equivalent filtration equipment as a primary deliverable, suggesting the code sees limited or sporadic activity in state and local markets. Without evidence of current demand, this category warrants a watch status pending future opportunities that directly specify sintered aluminum filter media or assemblies.
