Intake ceiling. This is the documented heart of the 700 Series program: seven panels at 38.5" x 108", served by polyester diffusion media in the PA560G-10 and FF560GX families. That is a long panel, and long panels punish careless installation. Support each panel so it cannot sag mid-span, seat the edges fully in the frame, and change all seven together so plenum pressure stays uniform over the vehicle.

Make-up air and exhaust. The 700 Series, as a downdraft, runs a prefilter stage at the make-up air unit and arrestor media at the exhaust, and Garmat installations in the field vary in rack style and grid dimensions. Because this record is catalog-discovered and those slots do not yet carry published SKU assignments here, we do not guess sizes on this page. A fitment check with photos of your AMU rack and exhaust grid, or a quote request with the nameplate, gets every slot matched from the distributor cross-reference before you commit.

Buying rhythm. Once the fitment check locks your sizes, the sensible pattern is ceiling panels on a fixed cadence with prefilters changed more frequently in between, since the prefilter stage exists to keep those seven long panels clean for their full service life.

For a 700 Series doing motor vehicle refinishing, EPA 6H applies in almost every case: the booth must operate with all filters in place, maintained to specification, with change records available. OSHA 1910.94(c) makes maintained ventilation a worker-protection requirement, not just a finish issue, and NFPA 33 treats overspray accumulation anywhere in the exhaust path as a combustible deposit. A seven-panel ceiling changed as a set, on a logged date, with prefilter and arrestor changes recorded alongside it, satisfies the documentation habit all three standards reward.
