UNSPSC 40161708: Cyclone separator and components

A cyclone separator is an economical device for removing particulate solids from a fluid system. The induced centrifugal force is tangentially imparted on the wall of the cyclone cylinder. This force, with the density difference between the fluid and solid, increases the relative settling velocity.

UNSPSC 40161708 Cyclone separator and components is a Commodity code that shows no relevant recent state and local procurement activity. The six opportunities posted between February and June 2026 in the source span highway and bridge construction, roundabout and expressway rehabilitation, law enforcement equipment procurement, and road resurfacing — none of which involve cyclone separators or related industrial separation equipment. The mismatch between the code's nominal scope and the actual solicitations suggests the code is either misapplied in state and local procurement systems or sees minimal activity in this market segment.

The recent opportunities themselves reflect active highway and transportation infrastructure spending across California, Georgia, and Washington state jurisdictions. Santa Clara County posted four infrastructure bids (bridge replacement, guardrail improvements, and pavement rehabilitation), Barrow County Georgia issued a road resurfacing RFB, the City of Marietta Georgia solicited roundabout construction under RFB 26-53444 with bids due June 26, 2026, and Sourcewell (Minnesota cooperative purchasing) issued RFP #061626 for law enforcement equipment on behalf of participating Washington and other state jurisdictions with proposals due June 16, 2026. No solicitations within this source set target cyclone separator procurement, industrial dust collection systems, or air separation equipment. Monitor this code for future activity, but current signal is minimal.
