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 a significant mismatch between its nominal scope and recent state and local procurement activity. The three most recent opportunities tagged under this code involve roundabout and expressway construction, law enforcement equipment procurement, and pavement rehabilitation — none of which involve cyclone separators or their components. The City of Marietta, Georgia's RFB 26-53444 (due June 26, 2026) solicits roundabout construction including utility relocation, grading, and storm sewer installation. Santa Clara County's ITBRDAFY260694 (due May 21, 2026) seeks pavement rehabilitation services along Central Expressway with partial depth recycling, asphalt overlay, and ADA improvements. Sourcewell's RFP #061626 (due June 16, 2026) establishes a cooperative purchasing contract for law enforcement equipment on behalf of participating entities across multiple states. None of these solicitations reference or require cyclone separators, filtration systems, or dust-collection equipment.

The code shows no relevant recent activity in state and local procurement. The opportunities posted under this UNSPSC number since late April 2026 are civil infrastructure and equipment supply work with no connection to the industrial separation, cyclone, or component procurement that the code nominally describes. Bidders evaluating this code should treat recent posting activity as a tagging error rather than a signal of actual market demand, and should verify whether their cyclone separator or component offerings are being sought under alternative UNSPSC codes or through direct vendor relationships with state departments of transportation, water and wastewater authorities, or environmental compliance agencies.
