Intake ceiling. The documented ceiling program is 30 panels at 20 x 48 inches. The catalog match is the 561-032 PA 560 G-10 solid intake panel in ceiling-diffusion polyester, which is the position that decides finish quality in any downdraft. Thirty panels is a real ceiling; replace it as a set so the plenum loads evenly, and expect the set to outlast several exhaust changes.

Exhaust grid. Exhaust media for the 2000 runs in 32 x 21 grid stock. Paper-backed arrestor rolls in that cut include SKUs 3325, 3606, and 20336630, with heavier fiberglass options in roll form such as 14AG30300 (30 inch x 300 foot) and 200-070 (30 inch x 100 foot) for higher-capacity loading. Paper-style media suits the grid format the 2000 was documented with; fiberglass trades a different loading curve for higher holding capacity. Pick one and change on pressure, not appearance.

AMU pre-filter. The make-up air stage takes a 25 x 72 inch link pre-filter: 0162525726 in the non-tacky 3-ply construction or 010-061 in the tacky panel-linked version. Tacky media holds fine dust better ahead of a burner; non-tacky is the cleaner-handling default. This stage cycles independently of the booth positions and protects the most expensive components in the system.

A 2000 still spraying today answers to current rules regardless of its build date. NESHAP 6H requires exhaust filtration maintained per manufacturer recommendation with documented changes; the catalog-documented media program plus dated delivery records is the maintenance trail that works in practice. OSHA 1910.94(c) requires design airflow while spraying, which on an older downdraft is lost first to overloaded 32 x 21 exhaust media. NFPA 33 treats saturated arrestor as combustible accumulation, so loaded rolls and pads leave the building on the same day they leave the grid. Nothing about the booth's age changes the obligations; it only changes how good your records need to be.
