The AirTAC Airtac GAC F.R.L. Combination Units GAC30010AST is a genuine three-unit F.R.L. combination — a filter, a pressure regulator and a lubricator pre-assembled on one bracket with quick mounting clamps. It has 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).
Air arrives cleaned, held at a stable set pressure and carrying a controlled oil mist, because the GAC30010AST strings a filter, a regulator and a lubricator together on one L-shape bracket with quick clamps. The 3/8" NPT ports seal by thread taper, a familiar choice on North American pipework, and the fitted circular gauge reads psi/bar, the scale the T code assigns. As a standard-type unit it regulates 0.15-0.9 MPa (20-130 psi) against a 1.0 MPa (145 psi) ceiling, with a 40 um element that suits general shop air. Its automatic drain empties the 60 cc condensate bowl unattended, while the 98 cc oil bowl meters ISO VG 32 into the air after the regulator, so oil mist never fouls the regulating seat. The whole 1300 g assembly needs its own panel or frame mount, not support from the piping.

Constituent units, orderable separately as spares: GAF300-10 filter, GAR300-10 regulator, GAL300-10 lubricator — all three share this body and port.
Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Case sealers and taping heads run cylinders that need both moisture-free air and light lubrication; the automatic drain keeps condensate off the valves during long shifts.
A maintenance bench running impact guns and ratchets benefits from the 40 um element upstream and continuous oil mist at the tool.
Feeding clamps, tool changers and cool-air nozzles around a CNC cell, the 3/8" port and mid-size bowls suit a shared drop point.
The 3/8in port sits mid-range in the GA series: for heavier mains the GAC400 doubles the plotted curve, while the GAC200 halves it for small jigs. The PC bowl comes as standard here; order a C metal or N nylon bowl variant if the surroundings call for it, confirming material compatibility from the datasheet. Replacements keep the same body-port suffix - GAF300-10, GAR300-10 and GAL300-10 - so a clogged element or cracked bowl never forces a whole new assembly. Because the lubricator injects oil downstream of the regulator, specify a GAFR filter-regulator instead if the downstream line must stay oil-free. On sizing: the catalogue flow curve for this GAC300 is plotted to 3000 L/min at 0.7 MPa inlet, and stepping to the GAC400's 6000 L/min curve roughly doubles it - a 2x envelope gap to weigh against that body's 2390 g frame.
Quick checklist
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a filter-regulator instead of an F.R.L. combination on that branch.
Working range is 0.15-0.9 MPa (20-130 psi) on this standard type, with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc and the oil bowl 98 cc, the unit weighs 1300 g, and the recommended lubricant is ISO VG 32 or equivalent.
The trailing T in the order code selects NPT ports and switches the gauge scale to psi/bar to match North American practice. If your operators read MPa, the same body with the default PT thread (GAC30010AS) carries a gauge scaled MPa/psi instead - pick whichever scale your crew checks daily.
