Intake side. The 2000 Maxidraft Option 1 uses Saima's pressurized ceiling-diffusion plenum with European-spec polyester or fiberglass diffusion media filling the panel grid. Standard panel dimensions follow Saima's downdraft-compatible ceiling set; the nameplate plus a single ceiling-panel photo confirms the exact set. AMU pre-filter cycle on Option 1's base air-handler package typically runs 60-90 days; the ceiling diffusion media itself cycles 30-60 days depending on production tempo.

Exhaust side. Pit-mounted exhaust pad media, Option 1 uses the smallest of the three Maxidraft exhaust-pit slot configurations. The catalog kit defaults to fiberglass arrestor pad (the most common spec across Italian downdraft installations), with polyester arrestor as the upgrade path for shops running higher-solids or waterborne finishes where fiberglass loads faster than the cycle wants. The 25-entry filter media taxonomy on this site distinguishes fiberglass-arrestor, polyester-arrestor, accordion-paper, paper-mesh, pocketed-paper, cube-overspray-arrestor, and tower-exhaust-pocket-bag among the 12 exhaust types, the Option 1 verified-fitment kit names the specific media-type slug per slot.

Slot expectations are queued for re-mapping. A note on transparency: the booth-model slot expectations row for the 2000 Maxidraft Option 1 is currently flagged in the 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. Intake-ceiling at 30-60 day cycle; AMU pre-filter at 60-90 day cycle; exhaust-pit pad at 7-14 day cycle for high-production collision, 21-30 day cycle for lower-volume. Subscription delivers each position on its calibrated cadence; the maintenance log flags the position when the calibrated cycle is approaching.

2000 Maxidraft Option 1 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 with this booth fall under 6H Area Source category under NESHAP Subpart HHHHHH, which requires the booth to be operated and maintained per the manufacturer's specifications and demands documentation of filter changes. Subscription delivery records produce the maintenance log most 6H authorities expect on audit. The original Saima capture-efficiency documentation accompanies each fitment shipment where the dealer-channel record retained it.
