Exhaust side. The exhaust wall grid is the workhorse slot, and the cross-reference gives you two roll options for it. The 22 gram fiberglass arrestor roll (30" x 300') is the economy default, cut to the grid on-site. The Paint Pockets roll (30" x 50') costs more per foot but holds substantially more overspray per change, which pays off in high-volume spraying. Pick one and stay with it so your pressure-drop readings stay comparable change to change.

Intake side. A classic crossdraft Performer draws air through intake media at the front of the booth, usually in the doors or the front face. The cross-reference also lists a Filtrair FF560GX diffusion panel at 51" x 121", which points at plenum-fed configurations within the family. Before ordering intake media, confirm whether your booth breathes through door filters or a plenum; the two take different products.

AMU prefilter. If your installation includes an air make-up unit, the listed six-pocket bag with header (23 1/4" x 47" x 8") protects its coil and burner. Unheated Performers drawing shop air skip this slot entirely, which is a configuration fact worth stating on your first order.

Crossdraft geometry concentrates the compliance story on the exhaust wall, because that grid is the single capture stage between overspray and the stack. EPA 6H expects filter technology achieving at least 98 percent capture efficiency, and on a Performer that is entirely a question of arrestor condition and coverage: gaps or blown-through media at the grid are the failure mode. OSHA 1910.94(c) adds a worker-exposure angle specific to horizontal airflow, since a loaded exhaust wall pushes overspray back into the painter's breathing zone before anything shows on a gauge. NFPA 33 treats the loaded grid as combustible loading, and it also expects bulk roll media stored away from the spray area.
