Intake side. The Ultra XL runs an expanded GFS pressurized ceiling-plenum intake with diffusion-grade media filling a larger panel grid than the Ultra XD. Polyester ceiling diffusion is the catalog default; fiberglass diffusion is the alternative for cleaner ambient profiles or aerospace-tier installations where particulate control is contractually specified. The expanded ceiling area means more total panels per kit; the cycle cadence per panel runs similar to the Ultra XD because airflow scales with the booth dimensions.

Exhaust side. Exhaust media on the Ultra XL is the GFS downdraft-pit arrestor pad family scaled to the wider XL pit. Fiberglass-arrestor is the catalog default; polyester-arrestor is the upgrade for waterborne and high-solids workloads. Aerospace-tier Ultra XL installations frequently spec HEPA-class final-stage filtration as a downstream addition for NESHAP Subpart GG compliance, that's a separate aerospace-class kit, kept distinct in the catalog from the standard collision-class fitment. Our 25-entry filter media taxonomy 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 Ultra XL verified-fitment kit names the specific media-type slug per slot.

Slot expectations are queued for re-mapping. Honesty note: the booth-model slot expectations row for the GFS Ultra XL in our database is currently flagged in the verification queue as pending re-mapping against the new 25-entry filter media taxonomy (we 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. Intake-ceiling at 30-60 day cycle; AMU pre-filter at 60-90 day cycle; exhaust-pit pad at 7-21 days depending on workload class. Aerospace-tier installations with HEPA final-stage cycle the HEPA at 12-24 months with documented capture-test data per shipment. Subscription delivery calibrates per position.

Ultra XL installations split across two compliance regimes depending on the operator. Standard collision and light-commercial Ultra XL installations sit under NESHAP Subpart HHHHHH 6H Area Source. Aerospace tier-supplier installations layer NESHAP Subpart GG (aerospace manufacturing and rework) on top, which requires HEPA-class final-stage filtration plus documented capture-test data formatted for federal aerospace recordkeeping. Subscription delivery records produce the maintenance log audit-ready under either regime, with capture-efficiency documentation accompanying every shipment. OSHA 29 CFR 1910.94 spray-finishing standards apply across the board.
