UNSPSC 26131609: Exhaust inlet stacks

UNSPSC 26131609 Exhaust inlet stacks, Commodity, encompasses equipment and systems for managing airflow discharge from industrial, commercial, and institutional processes — though recent state and local opportunities show little activity directly matching the code's nominal scope. Instead, the opportunities tagged under this code reflect renewable energy infrastructure, solar photovoltaic systems, power distribution maintenance, and HVAC exhaust system design and installation, which diverge materially from the traditional exhaust-stack product category. State and local buyers posting under this code include municipal utilities (City of Pasadena Department of Water and Power), county water districts (Eastern Municipal Water District), city facilities and procurement departments (City of Dallas Department of Facilities Management, City of South Fulton Procurement Department), county governments (Milwaukee County, DeKalb County), and state procurement offices (South Dakota via Sourcewell). Among these, Pasadena PWP and South Fulton have recently solicited work involving distributed energy resources, rooftop turbines, and solar PV maintenance. The Milwaukee County Community Reintegration Center laundry exhaust system project represents the closest match to traditional exhaust equipment, calling for design, furnishing, and installation of a new lint collection and exhaust system for two commercial dryers with approximately 20,000 CFM capacity.

Recent opportunities span California (Eastern Municipal Water District in Riverside County, City of Dallas), Georgia (DeKalb County, City of South Fulton), Wisconsin (Milwaukee County, City of Madison), and South Dakota. The most recent relevant opportunity is Milwaukee County's sealed-bid procurement (ITB2026LAUNDRYEXHAUSTSYSTEMINCLUDESREMOVALOFEXISTINGLAUNDRYLINTCOLLECTIONSYSTEMFORMILWAUKEECOUNTYCOMMUNITYREINTEGRATIONCENTER) for laundry exhaust system replacement at 8885 S. 68th St., Franklin, Wisconsin, with bids due June 3, 2026, requiring design, permitting, installation of a new code-compliant lint collection system, shop drawings, structural calculations, control system integration with Johnson Controls Metasys Building Automation System, and a minimum one-year labor warranty. The code shows considerable activity tagged to renewable energy and power systems procurement rather than traditional exhaust inlet stacks; vendors evaluating this code should verify the specific scope of work in each RFP or ITB, as the recent opportunities do not consistently align with the commodity's abstract name.
