UNSPSC 25202610: Microfilters

Microfilters are used as pre-filters for the efficient and continuous removal of solids such as rust, sand and other particulates from aviation fuels. Aviation microfilters are used in refineries, terminals and airport depots, primarily as pre-filters to lengthen the service life of downstream coalescer elements in filter/water separators.

UNSPSC 25202610 Microfilters is a Commodity code that covers the procurement of small filtration components for aircraft, ground equipment, and specialized systems in state and local public safety and transportation applications. The recent state and local solicitations under this code reflect acquisition of microfilters as components within larger mission-critical systems—notably installed within aircraft environmental control systems, hydraulic circuits, and auxiliary power units—rather than as standalone filter products. State and local issuing bodies pursuing work under this code include state transportation and public safety agencies (highway patrol, aviation authorities) and county airport operators managing commercial and public-use facilities. The work being solicited spans filtration components for new aircraft platforms, mission equipment integration on specialized aircraft, and equipment upgrades at public airports.

Recent activity concentrates in the Mountain West and Southeast. The South Dakota Highway Patrol issued RFP 26RFP19842 on July 9, 2026, for a public safety special mission aircraft solution including a Kodiak 100 Series III platform with integrated mission equipment for law enforcement and public safety operations, with proposals due July 20, 2026; microfilters feature in this procurement as components of the aircraft's environmental and fuel systems, but are specified and priced as part of the larger integrated aircraft and mission-equipment package rather than as line items. Okaloosa County, Florida issued ITB ITBAP3026 on March 18, 2026, for two mobile adjustable aircraft boarding ramps for Destin-Fort Walton Beach Airport with a due date of February 25, 2026; microfilters do not appear relevant to the boarding-ramp solicitation, indicating the code may be associated with aircraft-related specifications in the county's procurement taxonomy that do not directly apply to ground-support equipment. The code shows limited discrete demand for microfilters as standalone procurements in the recent state and local market; most microfilter acquisition appears bundled within larger aircraft platform or mission-equipment contracts where component specifications are nested within vendor proposals for integrated systems.
