Intake side. Front-wall intake bank with diffusion-grade media, typically polyester intake pad or paper-mesh depending on the build year and dealer install preference. The 8191's intake bank dimensions are documented in the Col-Met / GFS records; the verified-fitment record draws from authorized-dealer cross-references.

Exhaust side. Rear-wall exhaust bank with arrestor pad media. Fiberglass-arrestor pad is the most common spec across the 8191 installed base; polyester-arrestor as the upgrade for higher-solids and waterborne. The new 25-entry filter media taxonomy on this site distinguishes 12 exhaust types, fiberglass-arrestor, polyester-arrestor, accordion-paper, paper-mesh, pocketed-paper, cube-overspray-arrestor, tower-exhaust-pocket-bag, plus five more, alongside 9 intake types and 4 specialty types. The 8191 kit names its specific exhaust slug per slot.

Slot expectations queued for re-mapping. The booth-model slot expectations row for the Value Crossdraft 8191 is currently flagged in our verification queue as pending re-mapping against the new 25-entry media taxonomy (the platform expanded from 9 to 25 media types on 2026-05-09). The kit you receive is correct, we're updating the metadata record, not the physical fitment.

Cycle math. Front-wall intake media at 30-60 day cycle; AMU pre-filter (where present) at 60-90 day cycle; rear-wall exhaust pad at 7-21 day cycle for production shops, 21-45 day cycle for lower-volume operations. Subscription delivers each position on its calibrated cadence.

Col-Met Value Crossdraft 8191 installations run under regional AQMD or state-DEP authority for VOC and HAP control plus federal OSHA spray-finishing standards (29 CFR 1910.94). Most independent collision shops on an 8191 fall into NESHAP Subpart HHHHHH 6H Area Source category, requiring manufacturer-spec operation and filter-change documentation. Subscription delivery records produce the maintenance log most 6H authorities expect on audit.
